TNA Basics - 3x Leverage on Russell 2000
TNA (Direxion Daily Small Cap Bull 3X Shares) targets 3x the daily return of the Russell 2000 Index. Launched November 5, 2008 by Direxion. Expense ratio 1.00%, the highest among major 3x ETFs. Net assets ~$1.5 billion.
The Russell 2000 comprises the smallest 2,000 stocks in the Russell 3000, representing U.S. small-cap equities. Average constituent market cap is ~$3 billion vs S&P 500's ~$80 billion.
Average daily volume is ~15-20 million shares. TNA's defining characteristic is applying 3x leverage to Russell 2000's already-high volatility, making it one of the most volatile major leveraged ETFs.
Small-caps are more volatile than large-caps, and this high volatility amplified 3x creates extreme price swings and severe decay.
Small-Cap Characteristics - High Growth Expectations, High Volatility
The theoretical basis for small-cap investing is the small-cap premium from Fama-French's 3-factor model: small stocks historically outperform large stocks by ~2-3% annually over 1926-2024.
However, this premium has shrunk recently. Over 2010-2024, Russell 2000 returned ~+8% annually vs S&P 500's ~+13%. Large-cap tech dominance has worsened small-cap relative performance.
Russell 2000 annualized volatility is ~20-25%, 5-7% higher than S&P 500's 15-18%. Individual small-caps can reach 40-60% volatility. Low liquidity means spreads widen dramatically during stress.
Small-caps are also highly cyclical, strongly tied to U.S. domestic economic conditions. They outperform during expansions but underperform more severely during recessions.
Russell 2000 vs S&P 500 Volatility Impact
The critical question: how does the volatility difference between Russell 2000 and S&P 500 affect 3x ETF performance? Over 2015-2024: S&P 500 volatility averaged ~16%, Russell 2000 ~22%.
SPXL annual decay: -3 × (0.16)² = -7.7%. TNA annual decay: -3 × (0.22)² = -14.5%. Nearly double the decay. This 6.8% annual difference compounds dramatically over time.
With -14.5% annual decay, the underlying must return +14.5%+ just to match 1x. Russell 2000's recent ~+8% annual return means: 3×8% - 14.5% = 9.5%, which underperforms even S&P 500 at 1x (+13%).
This mathematical reality shows TNA long-term holding is structurally disadvantaged. Unless small-cap premium revives to +15%+ annual returns, TNA will continue underperforming SPXL.
TNA vs SPXL - Same 3x, Vastly Different Outcomes
Over 2010-2024: SPXL returned approximately 30-40x. TNA returned approximately 5-10x. Same 3x leverage, 4-8x difference in final returns. The gap is primarily volatility decay.
In up years, TNA can beat SPXL (e.g., 2020 when Russell 2000 outperformed S&P 500). But down-year losses are larger for TNA, so cumulative long-term returns favor SPXL overwhelmingly.
Compound math illustration: at same +10% underlying return but different volatility (16% vs 22%), 10-year results diverge dramatically. SPXL: (1 + 0.30 - 0.077)^10 ≈ 7.5x. TNA: (1 + 0.24 - 0.145)^10 ≈ 2.4x. Volatility difference is decisive.
Investors should not assume small-cap × 3x = maximum returns. The math shows the opposite: higher volatility destroys leveraged returns.
Past 10-Year TNA Performance
Over 2015-2024, TNA's total return was approximately +200-300% (3-4x). SPXL: +800-1,000% (9-11x). TQQQ: +2,000-3,000% (21-31x). TNA is the worst performer among major 3x ETFs.
Worse, TNA underperformed IWM (Russell 2000 1x) during 2018-2020 when the index was flat to slightly up. Decay consumed returns entirely. A leveraged ETF losing to its own 1x index is the worst-case scenario realized.
Annual return distribution shows extremes: +110% (2020) and -45% (2022). Timing errors are catastrophic. Buying at 2021 year-end meant -45% by 2022 year-end.
TNA's poor performance reflects the post-2010 large-cap dominance environment. Until this reverses, TNA's relative performance will not improve.
Can the Small-Cap Premium Be Captured at 3x?
The small-cap premium (+2-3% annually) at 3x gives +6-9% excess return. But Russell 2000's additional decay vs SPXL is -6.8% annually. Net: -0.8% to +2.2%. The premium nearly vanishes.
Furthermore, the premium is not constant. It disappears for 10-20 year stretches. 2010-2024 was such a period, with Russell 2000 underperforming S&P 500 by 5%+ annually.
The rational case for TNA exists only if you bet on small-cap premium revival: rate cuts, economic recovery, large-cap tech valuation correction. But timing this is extremely difficult.
Understanding the relationship between base index volatility and leveraged returns is essential for ETF selection. Small-cap investing books on the small-cap premium theory and evidence can help you judge whether TNA aligns with your investment thesis. Use compound interest calculators with volatility decay to avoid overly optimistic expectations.
