SNK -2x GraniteShares 2x Short SpaceX Daily ETF

SNK targets -2x the daily return of underlying — not the cumulative return over multi-day windows. The fund rebalances at the close each day using swaps or futures, which is what creates the volatility drag the chart above visualizes.

Mathematical headline: drag ≈ −0.5 × N × (N−1) × σ² per period. For a -2x product on an underlying with 25% annualized vol, expected annual drag is around 6.2%. Add expense ratio and the realized number is typically worse.

• Short-term tactical: daily and intraday holds are where these products were designed to live.
• Premium selling: options on SNK carry very rich IV — see the quote page for IV rank and straddle pricing.
• Multi-day directional: works in strong trends; gets eaten alive in chop. Use the chart above to gauge the realized vs theoretical track record.
