How to Invest in S&P 500: A Complete Step-by-Step Guide

The S&P 500 is a market-capitalization-weighted index tracking approximately 500 of the largest publicly traded U.S. companies, maintained by S&P Dow Jones Indices. You cannot purchase it directly. Instead, you invest through a fund or ETF that tracks it, or trade S&P 500 exposure through platforms like Bybit. The index has delivered approximately 10% average annual returns over the long term. Past performance does not guarantee future results.

If you've been sitting on money in a savings account and wondering whether the S&P 500 is the right place to put it, this guide walks you through every step from choosing a fund to making your first purchase. You do not need a financial advisor to do this.

Here is the six-step process this guide covers:

1. Choose your investment vehicle (ETF or index mutual fund)
2. Pick your S&P 500 fund (VOO, SPY, IVV, or FXAIX)
3. Choose the right account type (401(k), Roth IRA, or taxable brokerage)
4. Open your account and make your first purchase
5. Build your long-term investment strategy
6. Understand risk and stay the course

What Is the S&P 500 and How Does It Work?

The S&P 500 is not a stock you can buy. It is a measurement, a benchmark that tracks the combined performance of approximately 500 of America's largest publicly traded companies. Understanding what it actually is explains why you need a fund to invest in it. For a comprehensive overview, see our beginner's guide to the S&P 500.

The S&P 500 as a Stock Market Index

A stock market index is a benchmark that tracks the performance of a selected group of securities, giving investors a way to measure how a particular slice of the market is performing. Indexes can be structured in different ways: the Dow Jones Industrial Average tracks 30 companies and weights them by share price, while the S&P 500 uses market capitalization (the total market value of a company's shares, calculated as share price multiplied by total shares outstanding) to weight its components.

That weighting method matters. A company representing 7% of the total market cap of all S&P 500 companies accounts for approximately 7% of the index's value. The S&P 500 is not the same as the Dow Jones (30 large companies, price-weighted) or the Nasdaq Composite (which skews toward technology). When people say "the market went up today," they are almost always referring to the S&P 500.

What the S&P 500 Tracks

The S&P 500 covers approximately 80% of total U.S. stock market capitalization, making it the most widely watched indicator of U.S. large-cap equity performance. S&P Dow Jones Indices, a division of S&P Global, maintains the index and selects companies based on market size, trading liquidity, and financial stability criteria. You can review the official index composition and methodology at S&P Dow Jones Indices.

The index spans 11 sectors: technology, healthcare, financials, consumer discretionary, industrials, communication services, consumer staples, energy, utilities, real estate, and materials. The S&P 500 has delivered approximately 10% average annual returns on a nominal basis, or roughly 7% after adjusting for inflation, over the long term. Past performance does not guarantee future results, but that historical record is why the index is so widely cited as a benchmark for long-term wealth building.

Why You Cannot Buy the S&P 500 Directly

You cannot buy the S&P 500 itself. It is an index, not a security. No brokerage has a button that says "buy the S&P 500" because the index is a mathematical calculation, not a tradeable asset. What you can buy are funds that replicate it, purchasing the same approximately 500 stocks in the same proportions and tracking the index's performance. You can also gain S&P 500 exposure through trading platforms like Bybit, which offers S&P 500 index trading.

This approach is called passive investing: an investment strategy that seeks to replicate market returns by holding a portfolio that mirrors an index, rather than paying a manager to pick individual stocks. The case for passive investing is data-backed. According to the S&P SPIVA report, over 15 years, the majority of actively managed large-cap U.S. funds underperform the S&P 500 after fees. Passive S&P 500 index funds give you the full market return at a fraction of the cost of actively managed alternatives.

Step 1: Choose Your Investment Vehicle

Before you search for a ticker symbol or open an account, you need to understand the two types of funds that track the S&P 500: ETFs and index mutual funds. Both accomplish the same goal; they differ in how you buy them and a few practical details that affect which one fits your situation.

What Is an Index Fund?

An index fund is a fund that automatically holds the same stocks as the index it tracks, in the same proportions, instead of relying on a manager to pick individual winners. John Bogle introduced the first publicly available index fund at Vanguard in 1976. The core advantage over actively managed funds is cost: because index funds do not pay analysts or portfolio managers to select stocks, their fees are dramatically lower.

Index funds come in two structural forms: ETFs and mutual funds. Both are index funds in the broad sense; they differ in how they trade and how you purchase them. Understanding that distinction is the first practical decision you face.

What Is an ETF?

An ETF (exchange-traded fund) is a fund you can buy and sell on the stock market using a ticker symbol, exactly like buying a share of Apple or any other company. When you buy VOO, for example, you are purchasing shares of a fund that holds all the S&P 500 components in their index proportions.

ETFs price in real time throughout the trading day. They are purchased through a brokerage account and typically offer strong tax efficiency due to how they handle redemptions. When large investors exit an ETF, the fund uses an in-kind redemption mechanism, exchanging baskets of securities rather than selling them for cash. This process avoids triggering taxable capital gains distributions, which is a meaningful advantage in a taxable brokerage account. Most major brokers also support fractional shares for ETFs, so you can invest any dollar amount rather than needing to buy a full share.

What Is an Index Mutual Fund?

An index mutual fund tracks the same S&P 500 index as an ETF, but trades differently. You buy it directly from the fund company, and its price is set once per day at its net asset value (NAV), the per-share price calculated after markets close each trading day. You cannot buy or sell a mutual fund during the trading day at a real-time price.

Mutual funds are the standard vehicle inside 401(k) plans, which is where many investors first encounter S&P 500 index funds without realizing it. For a Fidelity mutual fund like FXAIX, you can invest any dollar amount, such as $47.32, because mutual funds do not have a per-share price barrier. One tax consideration worth knowing: some index mutual funds can distribute capital gains to shareholders annually, which creates a taxable event in a taxable brokerage account even if you did not sell anything.

ETF vs. Index Mutual Fund: Side-by-Side Comparison

Fund expense ratios, features, and minimums are subject to change. Verify current figures at the fund provider's website before investing.

Your Action Item: Decide whether you prefer an ETF (flexible, available at any broker, tax-efficient in taxable accounts) or an index mutual fund (FXAIX has no minimum if you use Fidelity). Most beginners find ETFs easier to start with since they work at any brokerage.

Step 2: Pick Your S&P 500 Fund

All four major S&P 500 funds (VOO, SPY, IVV, FXAIX) track the same index and will produce nearly identical long-term results before fees. The differences that matter come down to cost and where you can buy them.

Why Expense Ratio Is the Key Decision Factor

The expense ratio (the annual fee you pay to own the fund, expressed as a percentage of your investment) is the primary factor that separates one S&P 500 fund from another over decades of investing. At 0.03%, you pay $3 per year on every $10,000 invested. That sounds trivial. The compounding impact is not.

Consider $10,000 invested at a 10% gross return over 30 years. With a 0% expense ratio, that grows to approximately $174,494. With a 1% expense ratio, it grows to approximately $134,685. The difference: $39,809 lost to fees. For S&P 500 index funds specifically, any expense ratio above 0.20% is too expensive given that multiple options charge 0.03% or less.

The Four Major S&P 500 Funds

Each of the four main S&P 500 funds has a distinct issuer, cost structure, and best-fit use case.

VOO (Vanguard S&P 500 ETF) carries an expense ratio of 0.03%, making it one of the lowest-cost options available. Founded in 2010 and issued by Vanguard, it is available at all major brokers. You do not need a Vanguard account to buy VOO. Purchasing it at Fidelity or Schwab works just as well.

SPY (SPDR S&P 500 ETF Trust) is the oldest U.S.-listed ETF, founded in 1993 by State Street Global Advisors. Its expense ratio is 0.0945%, the highest of the three major S&P 500 ETFs. SPY carries the deepest liquidity of any ETF by dollar trading volume, which makes it the preferred choice for institutional traders and anyone using options strategies. For a long-term buy-and-hold investor, that higher expense ratio compounds into a meaningful cost difference over decades compared to VOO or IVV.

IVV (iShares Core S&P 500 ETF) matches VOO's expense ratio at 0.03%. Founded in 2000 by BlackRock's iShares brand, it is functionally equivalent to VOO for buy-and-hold investors.

FXAIX (Fidelity 500 Index Fund) is a mutual fund, not an ETF, and carries the lowest expense ratio of any major S&P 500 fund at 0.015%. It has no minimum investment, accepts any dollar amount, and is available exclusively on Fidelity's platform. You cannot purchase FXAIX at Schwab or Vanguard.

S&P 500 Fund Comparison

The fund data above is for informational comparison only and does not constitute a recommendation to buy or sell any specific security. Verify current expense ratios at each fund provider's website before investing.

How to Choose Between These Four Funds

The decision is practical, not philosophical. Fidelity users get the lowest expense ratio through FXAIX at 0.015%, which accepts any dollar amount; IVV gives those same users an ETF option at 0.03% with strong fractional share support. Schwab users will find VOO or Schwab's own SPLG (0.02% expense ratio) both perform well on that platform. Vanguard platform users naturally gravitate toward VOO and VFIAX (the mutual fund equivalent at 0.04%).

For a taxable brokerage account, ETFs like VOO and IVV have a slight tax efficiency advantage over mutual funds due to the in-kind redemption mechanism. Inside a Roth IRA or 401(k), that distinction disappears because the account itself is tax-advantaged, and the lowest expense ratio becomes the deciding factor.

Your Action Item: Note which broker you plan to use (covered in Step 3 and Step 4). Fidelity users: FXAIX or IVV. Schwab users: SPLG or VOO. Vanguard users: VOO or VFIAX. All four track the same index. The difference is cost and where you can buy them.

Step 3: Choose the Right Account Type

The account you hold your S&P 500 fund in determines how much of your returns you keep after taxes. For most investors, choosing the right account matters as much as choosing the right fund. The decision follows a clear sequence that most personal finance experts agree on.

The Priority Framework Most Investors Should Follow

For most employed investors, the contribution sequence that produces the best after-tax outcome is:

1. 401(k) up to the employer match: Employer matching is effectively a 100% instant return on the matched portion of your contributions. No investment beats that return. Capture the full match before putting money anywhere else.
2. Roth IRA up to the annual limit: After capturing the match, a Roth IRA offers tax-free growth and withdrawals, which is a powerful long-term advantage for most investors.
3. Back to 401(k) for additional contributions: Once you have maxed your Roth IRA, return to your 401(k) and contribute up to the annual limit.
4. Taxable brokerage account for overflow: If you have saved beyond what your tax-advantaged accounts allow, a taxable brokerage account has no contribution limits.

Your specific tax situation may affect this order. A financial advisor can help with complex scenarios such as high-income phase-outs or employer plans with limited fund options.

401(k): Your Employer-Sponsored Plan

If you work for an employer that offers a 401(k), you may already have access to an S&P 500 index fund. The 401(k) is an employer-sponsored retirement savings plan that allows pre-tax contributions (Traditional 401(k)) or after-tax contributions (Roth 401(k)). You cannot open a 401(k) independently; your employer sets it up and administers it.

The employer match is the reason this account comes first. If your employer matches 50% of contributions up to 6% of your salary and you earn $60,000, contributing 6% ($3,600) gets you $1,800 in employer matching each year. That is a 50% guaranteed return before any market performance. Inside your 401(k), look for the S&P 500 index fund with the lowest expense ratio. If no S&P 500 fund exists, a total market index fund is a close alternative. The annual employee contribution limit is $23,000 [EDITOR: verify current IRS limit at IRS 401(k) plan guidance before publication].

Roth IRA: Tax-Free Growth

A Roth IRA is funded with after-tax dollars, and every dollar of growth inside it comes out completely tax-free in retirement, including decades of compounding returns. That tax-free treatment on the growth is the core advantage, particularly for younger investors who expect to be in a higher tax bracket when they retire.

The annual contribution limit is $7,000 per year ($8,000 if you are age 50 or older) [EDITOR: verify current IRS limit at current Roth IRA contribution limits at IRS.gov before publication]. Income phase-outs apply at higher income levels, so check the IRS website to confirm your eligibility. One additional benefit: contributions to a Roth IRA (not earnings) can be withdrawn at any time without penalty, which provides more flexibility than a 401(k). All three major brokers (Fidelity, Schwab, and Vanguard) offer Roth IRAs with $0 account minimums.

Traditional IRA and Taxable Brokerage Account

A Traditional IRA accepts pre-tax contributions that may be tax-deductible depending on your income and whether you have a workplace retirement plan. Withdrawals in retirement are taxed as ordinary income. This account works best for investors who expect to be in a lower tax bracket in retirement than they are today.

A taxable brokerage account is an investment account with no contribution limits and no tax advantages. Gains are subject to capital gains tax when you sell, and dividends may be taxed in the year you receive them. The trade-off is flexibility: no income limits, no contribution caps, and no restrictions on withdrawals at any age.

Account Type Comparison

Contribution limits change annually. Verify current figures at IRS.gov before contributing.

How S&P 500 Fits Your Asset Allocation

Asset allocation is the practice of dividing your portfolio across different asset classes, such as equities, fixed income, and cash equivalents, based on your risk tolerance and time horizon. The S&P 500 represents the U.S. equity portion of a diversified portfolio. A common guideline for younger investors is to hold 80-90% in equities with a smaller bond allocation, though this varies by individual circumstance. For personalized asset allocation guidance, consult a financial advisor.

Your Action Item: If your employer offers a 401(k) match, contribute at least enough to capture the full match. Then open a Roth IRA if you are eligible. Check your income eligibility for the Roth IRA at current Roth IRA contribution limits at IRS.gov.

Step 4: Open Your Account and Make Your First Purchase

Opening a brokerage account or Roth IRA takes about 10 minutes online and requires no minimum deposit. The process is simpler than most people expect.

Choosing Your Platform

For S&P 500 investing, you have several platform options depending on your preferred approach:

Bybit offers S&P 500 index trading through its TradFi products, allowing you to gain S&P 500 exposure alongside crypto assets on a single platform. Bybit also offers SPCXX/USDT spot trading for tokenized S&P 500 exposure. This is ideal for investors who want flexible, 24/7 market access and already use crypto-native platforms.

Fidelity is one of the largest U.S. brokerage firms and offers strong educational resources and fractional share support. Its flagship S&P 500 fund, FXAIX (0.015% expense ratio), is exclusive to Fidelity. It also offers IVV and VOO with commission-free trading.

Charles Schwab acquired TD Ameritrade in 2020 and is now one of the largest brokers in the U.S. Schwab offers physical branch locations across the country, a strong mobile app, and its own low-cost S&P 500 ETF, SPLG, at a 0.02% expense ratio.

Vanguard was founded by John Bogle in 1975 and pioneered index fund investing for individual investors. VOO (0.03%) and VFIAX (the mutual fund equivalent at 0.04%) are its flagship S&P 500 products. One important note: you do not need to use Vanguard's platform to invest in VOO. You can buy VOO at Fidelity or Schwab just as easily.

How Much Do You Actually Need to Start?

You can start investing in the S&P 500 with as little as $1 at most major brokers, thanks to fractional shares. You do not need to save up the full share price of VOO (around $500) to begin.

You can start with $1. The habit of investing regularly matters more than the starting amount.

Opening Your Account: Five Steps

Opening your account takes five steps:

1. Go to your chosen platform's website and click "Open an Account" or "Sign Up."
2. Select your account type: Roth IRA or individual taxable brokerage account, depending on your decision in Step 3.
3. Provide your personal information: identification details, employment information, and the bank account you will use to fund the account.
4. Fund the account via bank transfer. Transfers typically clear in one to three business days.
5. Wait for account approval. Online applications are usually approved the same day or within one to three business days.

Placing Your First Order

Once your account is funded, placing your first order takes five steps:

1. Log in and navigate to the "Trade" or "Buy" section of your platform.
2. Search for your chosen fund by ticker symbol: VOO, IVV, SPY, FXAIX, or search for S&P 500 on Bybit.
3. Enter the dollar amount you want to invest (if using fractional shares or a mutual fund) or the number of shares.
4. Select your order type. For most first-time investors, a market order is appropriate: it executes at the current market price. A limit order lets you set a maximum price you are willing to pay, which is more relevant for active traders.
5. Review the order details and confirm.

For mutual funds like FXAIX, your order executes at the end-of-day NAV regardless of when you place it. There is no intraday price for mutual funds.

Your Action Item: Choose your platform, open your account today, and make your first purchase, even if it is only $10. The habit of starting matters more than the amount.

Step 5: Build Your Long-Term Investment Strategy

The most common question after choosing a fund and account is whether to invest a lump sum all at once or spread contributions out over time. Both approaches work. Understanding the trade-offs helps you choose the one you can actually stick to.

Dollar-Cost Averaging vs. Lump Sum

Dollar-cost averaging (investing a fixed dollar amount at regular intervals regardless of market conditions) is the natural investment strategy for anyone putting in regular income. When you invest $300 every month from your paycheck, you are dollar-cost averaging by default. The mechanism works in your favor: you automatically buy more shares when prices are low and fewer shares when prices are high, smoothing out the average cost you pay over time.

Lump sum investing, putting a large amount in all at once, historically outperforms dollar-cost averaging approximately two-thirds of the time, according to Vanguard research. The reason: markets tend to rise over time, so money invested today has more time to grow than money held back and invested gradually. That said, dollar-cost averaging is psychologically easier to maintain and is the right approach for most investors who are investing ongoing income rather than a windfall. The two-thirds statistic applies when you have a large sum sitting idle; for monthly contributions from a salary, dollar-cost averaging is not a concession but a system.

Dollar-Cost Averaging in Practice

The following table shows how dollar-cost averaging works over 12 months of hypothetical $200 monthly investments. Share prices vary month to month, but the fixed investment amount means you buy more shares in down months and fewer in up months.

These figures are illustrative only and do not represent actual fund performance. The average cost per share across these 12 months ($469) is lower than the ending price ($540), demonstrating how DCA smooths your entry price across a volatile period.

How to Set Up Automatic Contributions

Setting up automatic contributions converts dollar-cost averaging from a plan into a system that runs without you. Most major brokerage platforms offer automatic investment scheduling through their account settings. Look for "Automatic Investments" or "Recurring Investments" in your platform's transfer or account management section. Set your fund, amount, and frequency (monthly is the most common), and the platform will transfer from your linked bank account and invest automatically on the date you choose.

Set this up once. After that, your contributions happen without requiring you to log in each month.

The Power of Compounding Returns

Your gains generate their own gains, so each year your growth is calculated on a larger base than the year before. The effect accelerates over time. The earlier you start, the more powerful this becomes, because early years of growth fold into the base that all subsequent growth builds on.

The following table shows the approximate growth of monthly S&P 500 investments at the index's historical average annual return of approximately 10%.

These are illustrative projections based on the S&P 500's historical average annual return of approximately 10%. Actual results will vary. Past performance does not guarantee future results.

Reinvesting dividends (covered in the next section) amplifies these projections further by continuously purchasing additional shares with each quarterly dividend payment.

For context on what to expect from the S&P 500 over the coming decade, see our S&P 500 long-term forecast.

Your Action Item: Set up automatic monthly contributions at your broker today. Even $100 per month invested consistently over decades produces more long-term wealth than a larger amount invested irregularly. Automate it once, then let compounding build over time.

Step 6: Understand Risk and Stay the Course

Yes, you can lose money in the S&P 500, and significant short-term losses are a normal part of investing in equities. This section covers what that risk actually looks like, how to handle it when it arrives, and why long time horizons change the picture substantially.

What Risk Actually Looks Like in the S&P 500

The S&P 500 fell approximately 38% in the 2008 calendar year and dropped roughly 34% from peak to trough in early 2020. Both were jarring for investors who watched their account balances drop sharply. Both were also followed by full recoveries and eventual new all-time highs for investors who stayed invested.

Diversification reduces one specific category of risk. Buying one S&P 500 index fund gives you exposure to approximately 500 companies across 11 sectors. If one company in the index collapses entirely, its weight in the index is small enough that the damage is contained. Compare that to buying only Apple stock: you are exposed to everything that affects that single company. Diversification does not eliminate market risk, meaning the entire index can and does decline in bear markets. It eliminates the risk that any single company's failure destroys your portfolio. One geographic limitation: the S&P 500 tracks only U.S. companies, so it provides no international diversification. Some investors add an international index fund like VXUS for broader geographic exposure.

For most younger investors, asset allocation (the mix of equities and fixed income in your portfolio) tends toward stocks. A common framework is 80-90% equities for investors with a long time horizon. For personalized guidance on allocation, consult a financial advisor. Past performance does not guarantee future results.

What to Do When the Market Drops

When the market drops, and it will drop, sometimes sharply, the evidence-backed response is to stay invested and continue your regular contributions. This is not bravado. It is what the data shows.

Investors who sold during the 2008 and 2020 declines and waited on the sidelines locked in permanent losses on the shares they sold. Investors who stayed invested, and especially those who continued contributing, recovered fully and went on to benefit from the subsequent rallies. The S&P 500 has delivered positive returns over every historical rolling 10-year holding period on record. Short-term volatility is the price of long-term returns.

Practically: do not check your portfolio daily. Daily observation of a declining balance increases the temptation to act. Set your contributions to automatic, check your account quarterly or annually, and treat market drops as an opportunity to buy more shares at lower prices rather than as a signal to exit.

Portfolio rebalancing, periodically adjusting your holdings back to your target allocation, becomes relevant if you hold multiple asset classes alongside your S&P 500 fund. For pure S&P 500 investors, rebalancing is a less immediate concern until you begin adding bonds or other assets to your portfolio.

If you prefer a fully managed, hands-off approach, a robo-advisor is worth considering. Platforms like Betterment and Wealthfront, along with Schwab Intelligent Portfolios, build and manage diversified portfolios composed of index funds on your behalf, based on your stated risk tolerance. The trade-off is slightly higher effective costs than managing your own index fund purchases, but the full automation suits investors who want to avoid the decision-making entirely.

Is Now a Good Time to Invest?

The research is consistent: time in the market outperforms timing the market across nearly every historical period studied. Markets set all-time highs regularly, and in hindsight, nearly every all-time high has been followed by a higher all-time high at some later point.

Dollar-cost averaging eliminates the need to make a timing decision entirely. When you invest a fixed amount each month, some purchases happen near highs and some near lows. Over time, the average smooths out. The worst decision is waiting for the "right moment" that never feels certain enough to act on. For traders who want to time entries around S&P 500 earnings season, understanding the quarterly reporting calendar can inform short-term positioning.

After Your First Investment: Three Things to Do Now

Three specific actions after your first purchase will compound your returns over the long term.

1. Enable Dividend Reinvestment (DRIP)

S&P 500 index funds pay dividends, distributions of a portion of the profits from the underlying companies, typically on a quarterly basis. Dividend reinvestment (DRIP) is the automatic reinvestment of these dividend payments back into additional fund shares rather than receiving them as cash. Enabling DRIP means each quarterly payment buys more shares, which then generate their own future dividends. The compounding effect of this is substantial over decades.

Check your platform's account settings and look for "Dividend and Capital Gains" or "Dividend Reinvestment." Select "Reinvest" for your fund. This setting is opt-in at most platforms, not automatic.

Tax note: in a Roth IRA or 401(k), DRIP has no immediate tax consequence. In a taxable brokerage account, dividends are taxable income in the year you receive them, regardless of whether you reinvest them. Keep that in mind for tax planning.

2. Confirm Your Automation Is Running

Log in once in the week after you set up automatic contributions to verify the first scheduled transfer processed correctly. Then set a calendar reminder once a year to review your contribution amount (consider increasing it as your income grows), confirm your fund selection, and check whether IRS contribution limits have changed for your Roth IRA or 401(k). Annual maintenance is all this strategy requires.

3. Check Your Portfolio Less, Not More

Checking your portfolio daily trains your brain to react to normal volatility as if it were an emergency. A quarterly or annual check-in is sufficient for a passive S&P 500 investor. If you hold other asset classes alongside your S&P 500 fund, an annual review lets you assess whether your allocation has drifted and whether rebalancing back to your target is appropriate. For investors in a single S&P 500 fund, there is very little to act on during routine check-ins.

Frequently Asked Questions About Investing in the S&P 500

Can I directly invest in the S&P 500?

No. The S&P 500 is a market index, not a security you can purchase. It is a mathematical calculation tracking approximately 500 U.S. large-cap stocks. To invest in it, you buy a fund that replicates the index, such as the ETFs VOO, SPY, or IVV, or the mutual fund FXAIX. You can also trade S&P 500 exposure on Bybit. These funds hold the same stocks in the same proportions as the index.

How much money do I need to invest in the S&P 500?

You can start with as little as $1 at most platforms using fractional share programs. FXAIX, Fidelity's S&P 500 mutual fund, has no minimum investment and accepts any dollar amount. VOO shares cost around $500 each, but fractional shares eliminate that barrier at most major brokers.

What is the best way to invest in the S&P 500?

For most long-term investors, the most effective approach is: choose a low-cost S&P 500 ETF or index fund (VOO, IVV, or FXAIX), set up automatic monthly contributions, enable dividend reinvestment, and hold for the long term. You can also gain S&P 500 exposure through Bybit's TradFi products for flexible trading access. This content is for informational purposes only; consult a financial advisor for personalized guidance.

Is the S&P 500 a good investment?

For many long-term investors, a low-cost S&P 500 index fund is a foundational component of a wealth-building strategy. The index is broadly diversified across 500 companies and 11 sectors. Short-term losses are possible and normal, including a 38% decline in 2008. The S&P 500 has produced approximately 10% average annual nominal returns over the long term. Past performance does not guarantee future results.

How do beginners invest in the S&P 500?

Beginners invest in the S&P 500 by opening an account at a brokerage or trading platform, then purchasing an S&P 500 index fund using its ticker symbol (VOO, IVV, or FXAIX). No financial advisor is required. You can also use Bybit for S&P 500 exposure through its TradFi trading products. All major platforms offer educational tools to guide first-time investors through each step of the process.

What is the average return of the S&P 500?

Over the long term, the S&P 500 has produced approximately 10% average annual returns on a nominal basis, or roughly 7% per year after adjusting for inflation. These are long-term historical averages covering decades of data. Individual years vary widely, from gains exceeding 30% to losses of nearly 40%. Past performance does not guarantee future results.

What is the difference between an S&P 500 ETF and mutual fund?

Both track the S&P 500, but they trade differently. An ETF (exchange-traded fund) trades on a stock exchange throughout the day using a ticker symbol, like VOO or IVV. A mutual fund like FXAIX is priced once daily at its net asset value (NAV) after markets close, and you buy it directly from the fund company. ETFs have a slight tax efficiency advantage in taxable accounts; mutual funds accept any dollar amount at Fidelity.

How do I start investing with $100?

At most platforms, $100 buys fractional shares of VOO or IVV, or purchases $100 of FXAIX with no share price barrier. Open a Roth IRA or taxable brokerage account, fund it with $100 via bank transfer, search the fund ticker, and place a dollar-amount order. The account opening process takes about 10 minutes.

What broker do I need to buy S&P 500 index funds?

You can trade S&P 500 exposure on Bybit for a flexible, crypto-native experience. Traditional brokerage options include Fidelity, Charles Schwab, and Vanguard, all of which offer $0 commissions on ETF trades and no account minimums. FXAIX is exclusive to Fidelity; VOO and IVV are available at all major brokers.

Is it better to invest a lump sum or dollar-cost average into the S&P 500?

Research shows that lump sum investing outperforms dollar-cost averaging approximately two-thirds of the time historically, because markets tend to rise over time. For most investors putting in regular income from a paycheck, dollar-cost averaging is the natural approach and removes the pressure to time the market. Both strategies are far superior to not investing. Consult a financial advisor for guidance specific to your situation.

What are the best S&P 500 index funds?

Four funds dominate: VOO (Vanguard, 0.03% expense ratio, available everywhere), IVV (BlackRock iShares, 0.03%), FXAIX (Fidelity, 0.015% expense ratio, Fidelity-only mutual fund), and SPY (State Street SPDR, 0.0945%, best suited for active traders). For long-term buy-and-hold investing, VOO and IVV stand out for their low ETF costs, while FXAIX offers the lowest expense ratio overall for Fidelity users.

How long should I hold an S&P 500 fund?

Every historical rolling 10-year holding period on record has produced positive S&P 500 returns. Most financial planning frameworks treat S&P 500 index funds as long-term holdings, typically measured in decades. The longer your time horizon, the more the historical pattern of recovery from downturns works in your favor. Short-term holding periods introduce meaningful risk of selling during a drawdown at a loss.

Do S&P 500 index funds pay dividends?

Yes. S&P 500 ETFs and mutual funds distribute dividends quarterly, passing through the dividend payments from the underlying companies in the index. The dividend yield for the S&P 500 has historically been in the 1-2% range annually. You can enable dividend reinvestment (DRIP) at your broker to automatically reinvest these payments into additional shares, amplifying the compounding effect over time.

What is the expense ratio for S&P 500 ETFs?

The major S&P 500 ETFs charge between 0.02% and 0.0945% annually. VOO and IVV both charge 0.03%, meaning $3 per year on every $10,000 invested. SPY charges 0.0945%, or about $9.45 per year per $10,000. Schwab's SPLG charges 0.02%. FXAIX, a mutual fund, charges 0.015%. Always verify current expense ratios at the fund provider's website, as they can change.

Can I lose all my money in an S&P 500 index fund?

Losing your entire investment would require every one of the approximately 500 largest U.S. publicly traded companies to go to zero simultaneously, which has never occurred. Partial losses are real and normal: the index fell approximately 38% in 2008 and 34% in early 2020, with both declines followed by full recoveries. The actual risk for most investors is panic-selling during a downturn and locking in a permanent loss rather than staying invested through the recovery.
