A daily, tactical Nasdaq‑focused plan: buy QQQ in uptrends, move to T‑Bills when trends weaken, buy 2x QQQ after sharp selloffs, and pair cash with a VIX fund when the market looks overheated.

Every day it checks QQQ (Nasdaq‑100). RSI = a short‑term “heat gauge”: very hot (>79) → go defensive: 50% BIL (T‑Bills) + 50% VIXY (a fund that jumps when fear/volatility spikes). Very washed‑out (<29.5) → buy QLD (2x QQQ) for a rebound. Otherwise it looks at SPY’s trend: price above its 200‑day (or at least its 30‑day) average → own QQQ; if not → sit in BIL.

Out-of-sample, this Nasdaq-focused strategy offers higher risk-adjusted returns than the S&P 500: Sharpe ~2.62 vs 2.51, annualized return ~41.9% vs 30.0%, Calmar ~10.0. It blends mean-reversion, trend-following, and volatility hedges for robust upside with controlled risk.
