A simple, rules‑based switch: in stock uptrends it leans into 2× stock ETFs with some bonds and gold; in downtrends it buys only deep dips, otherwise parks in staples, gold, and the U.S. dollar. Rebalances only when weights drift substantially.

First, it checks if the S&P 500 (SPY) is above its 200‑day average (a long‑term uptrend). If yes, it goes risk‑on: uses 2× S&P (SSO) and sometimes 2× Nasdaq‑100/big tech (QLD) for growth, with some long‑term Treasuries (TLT) and Gold (GLD) for balance. If not, it’s risk‑off: it only buys SSO on sharp, short‑term drops (a 10‑day “oversold” reading says the fall is unusually strong); otherwise it holds defensive assets—Consumer Staples stocks (XLP), Gold (GLD), and the U.S. Dollar (UUP). It only rebalances when positions drift a lot.

In out-of-sample testing the strategy delivers ~35.2% annualized returns vs SPY ~20.6%, with lower drawdowns (~14.6% vs ~18.8%), and stronger risk-adjusted metrics (OOS Sharpe ~1.60, Calmar ~2.41).
