    "description": "After SPY or QQQ gaps down 0.75% or more with a red first 30-minute bar, does buying the matching -3x index fund at 10:00 ET and selling once the index recovers its open, or near the close, make money after costs? Pre-registered Backtrader backtest, 10 years of 30-minute bars, SPY, QQQ, SOXX and three -3x index funds (2016-10-18 to 2026-10-09) — verdict: THIN. Not enough evidence either way.
