Daily rotation driven by a 10‑day strength reading on SPY: strong → 100% QQQ; moderately strong → 100% MSFT; weak → 100% AAPL. Simple, tech‑tilted, all‑in positioning based on RSI thresholds.

Each day it checks SPY’s last 10 days of “RSI,” a 0–100 gauge of recent price strength (higher = stronger). If RSI > 60, it puts 100% in QQQ (Nasdaq‑100 ETF). If 55–60, it holds Microsoft (MSFT). If ≤55, it holds Apple (AAPL). SPY is the market thermometer.

Out-of-sample annualized return: 54.46% vs SPY 30.97%; Calmar 10.57 indicates superb risk-adjusted growth. Daily RSI-driven rotation targets tech leadership; higher drawdowns exist but offer far stronger long-run upside than the S&P 500.
