Compare AMZU leveraged ETF vs S&P 500. Learn risk, costs, performance, and which suits your investment horizon.
Last Updated: June 2025
Choosing between AMZU and S&P 500 ETFs comes down to more than returns. It is a decision shaped by how much single-stock concentration you accept, the cost gap between instruments, and how long you plan to hold. AMZU is Direxion's 1.5x leveraged Amazon ETF, built to amplify daily AMZN price moves. S&P 500 ETFs like SPY and VOO track 500 large-cap U.S. companies and form the backbone of most long-term retail portfolios.
This article compares both instruments across performance, risk, cost, and investor fit so you can make a clear, evidence-backed decision.

What Is AMZU? The Direxion Daily AMZN Bull 1.5X ETF Explained
AMZU is the ticker for the Direxion Daily AMZN Bull 1.5X Shares ETF, a single-stock leveraged ETF that seeks to deliver 1.5x the daily return of Amazon (AMZN) stock. Launched in 2022, it carries an expense ratio of ~0.95% and holds 100% of its exposure in AMZN derivatives. Unlike SPY or VOO, AMZU is not an index fund and tracks no diversified basket of securities.
Ticker Disambiguation AMZN = Amazon stock (the company, traded on NASDAQ) AMZU = Direxion's 1.5x leveraged ETF that tracks AMZN's daily price movement These are two separate financial instruments. One letter difference, meaningfully different risk profiles.
Direxion is a U.S.-based asset management company specializing in leveraged and inverse ETFs. The firm operates under SEC oversight and offers a range of single-stock leveraged products. AMZU is a regulated financial product from an established niche ETF provider.
The underlying asset driving AMZU is Amazon (AMZN), one of the largest companies in the world by market capitalization (~$1.8 to $2 trillion, approximate and date-sensitive). Amazon's stock price moves primarily on results from its key business segments: Amazon Web Services (AWS, the dominant cloud computing profit driver), advertising (a high-margin digital business), and e-commerce including Prime subscriptions. For current AMZN price data, see AMZN stock live price and market news.
The key distinction between buying AMZU and buying AMZN directly: AMZU resets its leverage ratio at the end of every trading day. AMZN is a direct equity holding that compounds over time without a daily reset mechanism. AMZU is built for short-term tactical use, not buy-and-hold investing.
What Is the S&P 500? Index Definition and How to Invest
The S&P 500 is a market-cap-weighted index tracking 500 of the largest publicly traded U.S. companies, and investors access it through ETFs rather than directly. In a market-cap-weighted index, larger companies hold greater weight, which means Amazon, Apple, Microsoft, and Nvidia each represent a meaningful slice.
The three primary S&P 500 ETF proxies are the SPY fund (SPDR S&P 500 ETF Trust) at ~0.0945% expense ratio, the VOO fund (Vanguard S&P 500 ETF) at ~0.03%, and IVV (iShares Core S&P 500 ETF) also at ~0.03%. SPY and VOO are index funds, meaning they passively track the S&P 500 without active stock selection. VOO costs less annually.
The S&P 500 has historically returned approximately 10% annually in nominal terms over the long run, driven by the natural compounding of reinvested returns across 500 companies. That figure is a long-term historical average, not a guarantee of future results. The S&P 500 also carries drawdown risk. SPY declined approximately 19% during the 2022 bear market and approximately 34% during the COVID crash of early 2020.
Amazon carries approximately 3-4% weight in the index (this fluctuates with Amazon's stock price and periodic rebalancing), meaning VOO already gives you partial Amazon exposure inside a diversified wrapper. The core structural contrast: S&P 500 ETFs spread exposure across 500 companies in 11 sectors. AMZU concentrates all exposure in one company, amplified daily.

AMZU's beta versus the S&P 500 is well above 2.0, meaning it moves more sharply than the index in both directions. The Sharpe ratio, which measures return per unit of risk taken, is expected to be lower for AMZU than for SPY or VOO over most multi-year periods. For current Sharpe ratio figures, check Portfolio Visualizer.
The expense ratio gap compounds meaningfully over time. The table below shows the dollar cost on a $10,000 investment.

| Holding Period | AMZU Cost | SPY Cost | VOO Cost |
|---|---|---|---|
| 1 Year | ~$95 | ~$9.45 | ~$3 |
| 5 Years | ~$485 | ~$48 | ~$15 |
| 10 Years | ~$985 | ~$96 | ~$30 |

Performance Analysis: Has AMZU Beaten the S&P 500?
AMZU's performance versus the S&P 500 depends on three variables: the time period measured, the market conditions during that period, and whether you measure raw returns or risk-adjusted returns.
When AMZU Outperforms
In periods of sustained Amazon upward momentum, AMZU's 1.5x daily leverage amplifies AMZN's gains substantially. During the 2023 Amazon recovery, when AMZN rebounded from its 2022 lows, AMZU delivered significantly higher raw returns than SPY over the same window. That is AMZU's strongest use case: directional momentum in AMZN's favor, held for days to weeks rather than months.
Raw outperformance in a bull market is real for AMZU. Whether that outperformance survives costs and risks over a longer hold depends on what happens next.
When AMZU Underperforms
AMZU launched in October 2022, which means its track record began after AMZN had already fallen more than 50% from its 2021 peak. During the bear market period of early 2022 through October 2022, AMZU's daily leverage amplified AMZN's losses on every down day. SPY's drawdown during that period was approximately 19-25%, while AMZU's drawdown was substantially deeper, in the range of 60-70%.
A hypothetical illustrates the downside: if AMZN declines 40% in a bear market, AMZU's losses would be amplified further by volatility decay, potentially exceeding a 60% drawdown. Past performance does not guarantee future results, and AMZU's limited track record since 2022 is not a sufficient basis for projecting long-term returns.
Risk-Adjusted Performance
Raw return comparisons between instruments with different risk profiles tell an incomplete story. The Sharpe ratio measures return per unit of risk taken. AMZU's Sharpe ratio is expected to be lower than SPY's or VOO's over most multi-year periods, because single-stock concentration and 1.5x leverage reduce risk-adjusted efficiency even when raw returns are higher. Use Portfolio Visualizer to compare current Sharpe ratio figures for both instruments.
Your investment horizon is the key variable. Over short trading windows with strong Amazon momentum, AMZU has historically delivered higher raw returns. Over multi-year periods in mixed or declining conditions, S&P 500 ETFs have been the stronger risk-adjusted performers.
The Hidden Cost of Leverage: Volatility Decay Explained
AMZU recalibrates its leverage ratio at the end of every trading day to maintain exactly 1.5x exposure to AMZN's next day return. The 1.5x multiple applies only to a single trading day. Over any multi-day or multi-month period, your actual return deviates from a simple 1.5x multiple of AMZN's total return. This daily recalibration creates path-dependency: the sequence of daily returns, not just the start and end price, determines what you receive over time.
The fund resets its starting line every morning rather than accumulating a lead from the day before. That structural feature is the mechanical cause of volatility decay. For regulatory context on leveraged ETF mechanics, see the SEC Investor Bulletin on Leveraged and Inverse ETFs.
How Daily Leverage Reset Works
Each trading day, AMZU uses derivatives to re-establish exactly 1.5x exposure to the next day's AMZN price movement. The fund does not track AMZN over a week, month, or year. It tracks AMZN one day at a time, every day.
This matters because gains and losses of different sizes are mathematically asymmetric. A 10% gain followed by a 10% loss does not return you to your starting point. It leaves you 1% below it. When a leverage multiplier is applied to each daily move, this asymmetry compounds against you whenever markets swing without a clear directional trend.
What Volatility Decay Does to Your Returns
Volatility decay (also called beta slippage) is the mathematical erosion of returns that occurs when an underlying asset's daily up-and-down swings interact with the daily leverage reset, causing the leveraged ETF to underperform a static leverage multiple over time.
The table below shows a three-day scenario where AMZN ends slightly positive and AMZU still loses ground.
Table 3: Volatility Decay, Three-Day Numerical Example
| Day | AMZN Start | AMZN End | AMZN Change | AMZU Start | AMZU End | AMZU Change |
|---|---|---|---|---|---|---|
| Day 1 | $100.00 | $110.00 | +10% | $100.00 | $115.00 | +15% |
| Day 2 | $110.00 | $100.01 | -9.08% | $115.00 | $99.31 | -13.64% |
| Day 3 | $100.01 | $103.01 | +3% | $99.31 | $102.29 | +4.5% |
| Result | - | $103.01 | +3% total | - | $102.29 | +2.29% total |
AMZN gained 3% over three days. AMZU gained only 2.29%, despite applying 1.5x leverage to each daily move. The gap between 3% x 1.5 (what you might expect: +4.5%) and the actual result (+2.29%) is volatility decay in action. For further context on how leverage risk compounds in single-stock ETFs, see how leverage risk compounds in single-stock leveraged ETFs.
The longer you hold AMZU in choppy or sideways conditions, the more this structural drag accumulates. In a sustained, directionally trending Amazon bull market, AMZU can amplify those gains. In volatile or declining conditions, volatility decay works against you on every swing in both directions.
Volatility decay is one of three key risks in AMZU. The other two are concentration risk and long-term holding risk, both covered next.
Risk Analysis: How Risky Is AMZU Compared to the S&P 500?
AMZU carries three distinct risk types that make it more volatile than S&P 500 ETFs: concentration risk, volatility and drawdown risk, and long-term holding risk.
Concentration Risk
Concentration risk is the risk of having all exposure in a single security. AMZU carries this risk at 1.5x magnitude. The fund holds 100% of its exposure in Amazon derivatives, with zero diversification at the security level.
If Amazon experiences a company-specific negative event, AMZU absorbs that event at 1.5x with no offsetting positions. A missed earnings quarter, a regulatory action against AWS, or a cloud computing sector downturn all hit AMZU harder than they hit any diversified fund. SPY spreads exposure across 500 companies in 11 sectors, so one company's bad quarter barely registers at the index level.
AMZU is also highly correlated with the broader market during sell-offs because Amazon is a top S&P 500 holding, but its leverage magnifies the severity of those correlated declines beyond what diversification provides.
Volatility and Drawdown Risk
Maximum drawdown is the largest peak-to-trough decline over a given period. AMZU's maximum drawdown since inception has significantly exceeded SPY's over the same window, reflecting both single-stock concentration and 1.5x leverage. Verify current drawdown figures using the ETFdb.com AMZU profile.
AMZU's standard deviation (a measure of how much the price swings above or below its average) runs above 70% annualized, compared to approximately 15-17% for SPY. AMZU's beta versus the S&P 500 is well above 2.0, meaning it moves more sharply than the index in both directions. In a scenario where AMZN falls 40% in a bear market, AMZU's losses would be amplified further by volatility decay, potentially exceeding a 60% drawdown.
Long-Term Holding Risk
AMZU is built for short-duration trades. The longer you hold AMZU without a sustained Amazon uptrend, the more volatility decay accumulates across choppy trading days. For investors with a 5-year or longer investment horizon, this structural disadvantage significantly reduces the probability that AMZU will outperform a simple S&P 500 ETF on a risk-adjusted basis.
S&P 500 ETFs carry real risk too. SPY declined approximately 19% in the 2022 bear market and approximately 34% during the COVID crash of 2020. But diversification across 500 companies limits both the depth and duration of drawdowns compared to a single leveraged position.
The trade-off is not whether risk exists, but whether the risk profile matches your investment horizon and conviction level.
Which Is Right For You? AMZU vs S&P 500 by Investor Profile
Your investment horizon is the single most important variable in this decision, and it points clearly toward two different instruments.
Choose AMZU If...
- Your investment horizon is days to weeks, not months or years
- You have strong, near-term conviction that Amazon will outperform the broader market over a specific short window
- You actively monitor positions and are comfortable with significant intraday price swings
- You understand and accept the risk of a 50% or greater drawdown on your position
- You have worked through how volatility decay affects returns over any holding period longer than one day
- AMZU is available through standard brokerage platforms including Robinhood, Schwab, Webull, and TD Ameritrade
Choose S&P 500 ETFs If...
- Your investment horizon is 5 years or longer
- You prefer passive, buy-and-hold investing without active position monitoring
- You want broad exposure to the U.S. economy rather than a concentrated single-stock position
- You prioritize capital preservation alongside long-term growth
- You want the lowest-cost path to market-average returns (VOO at ~0.03% expense ratio)
- You are building retirement savings or long-term wealth
If you want Amazon exposure inside a diversified portfolio, maintaining your S&P 500 ETF allocation already gives you that exposure through VOO's existing ~3-4% Amazon weighting. You do not need AMZU to hold a position in Amazon.
Final Verdict on AMZU vs S&P 500
For the majority of retail investors with a long-term investment horizon, S&P 500 ETFs (SPY, VOO) are the stronger choice. They cost less, diversify across 500 companies, and let your returns compound without the drag of daily leverage reset.
AMZU has a legitimate role for short-term, tactical traders with strong near-term Amazon conviction who understand daily leverage reset mechanics, actively monitor their positions, and treat AMZU as a time-limited directional trade rather than a portfolio holding.
The single most important variable in this decision is your investment horizon. If your horizon is days to weeks and you have high Amazon conviction, AMZU may be relevant as a tactical allocation. If you are investing for 5, 10, or 20 years, the S&P 500 is the structurally superior vehicle on cost and risk-adjusted return grounds.
Whatever your choice, verify current performance data, expense ratios, and maximum drawdown figures at the ETFdb.com AMZU profile or Portfolio Visualizer before committing capital.

Frequently Asked Questions: AMZU vs S&P 500
What is AMZU ETF?
AMZU is the Direxion Daily AMZN Bull 1.5X Shares ETF, a single-stock leveraged ETF that seeks to deliver 1.5x the daily return of Amazon (AMZN) stock. Issued by Direxion and launched in 2022, it carries an expense ratio of ~0.95% and resets its leverage ratio at the end of every trading day.
How does AMZU compare to the S&P 500?
AMZU offers 1.5x daily exposure to a single stock with ~0.95% annual fees and zero diversification. S&P 500 ETFs like SPY and VOO track 500 companies with no leverage and fees as low as ~0.03%. AMZU suits short-term trading. S&P 500 ETFs suit long-term compounding.
Is AMZU a good long-term investment?
AMZU is not built for long-term buy-and-hold investing. Its daily leverage reset produces volatility decay that erodes returns over extended holding periods in anything other than a persistently rising Amazon market. For 5-year-plus horizons, S&P 500 ETFs are structurally better suited.
What are the risks of holding AMZU?
AMZU carries three primary risks: concentration risk (100% single-stock exposure at 1.5x with zero diversification), volatility decay (daily reset erodes returns in sideways or volatile markets), and expense ratio drag (~0.95% annually versus ~0.03% for VOO). All three compound against long-term holders.
What is the expense ratio of AMZU?
AMZU's expense ratio is approximately 0.95% per year, as listed on the Direxion fund page. On a $10,000 investment, that is approximately $95 per year. VOO charges approximately 0.03%, or ~$3 per year on $10,000. Over 10 years, the cumulative cost difference on a static $10,000 position is approximately $955 using a simplified linear calculation.
Does AMZU outperform the S&P 500?
It depends on the period and market conditions. AMZU has outperformed SPY during sustained Amazon bull markets. In bear markets and choppy sideways conditions, volatility decay causes significant underperformance. Over AMZU's limited track record since its 2022 inception, performance has varied substantially by period. Past performance does not guarantee future results.
What is volatility decay in leveraged ETFs?
Volatility decay (also called beta slippage) is the mathematical erosion of returns caused by daily leverage reset. Because percentage gains and losses are asymmetric, up-and-down price swings create a gap between AMZU's actual return and what a simple 1.5x multiple would suggest, causing underperformance over time in volatile or directionless markets.
Is it better to buy AMZU or Amazon stock directly?
For long-term Amazon conviction, buying AMZN directly is more appropriate. AMZN compounds without daily reset mechanics, volatility decay, or the ~0.95% annual expense ratio. AMZU is suited for short-term leveraged trading with daily position monitoring. For most investors holding Amazon beyond a few weeks, AMZN is the more appropriate vehicle.
How much leverage does AMZU use?
AMZU uses 1.5x daily leverage, resetting this ratio at the end of every trading day. The 1.5x multiple applies only to a single day's return of AMZN, not to any multi-day or multi-month holding period. Holding AMZU for a week or month will not produce 1.5x of AMZN's return over that period.
What ETFs track the S&P 500?
Three major ETFs track the S&P 500. SPY (SPDR S&P 500 ETF Trust) charges ~0.0945% and has the highest daily trading volume. VOO (Vanguard S&P 500 ETF) charges ~0.03% and is among the lowest-cost options. IVV (iShares Core S&P 500 ETF) also charges ~0.03%. All three deliver essentially identical index exposure.
