Use 3x S&P/Nasdaq funds in uptrends; switch to cash‑like T‑bill ETFs in downtrends. Extra safety checks can move to cash faster or briefly short semiconductors. Small slices of AVGO, JNJ, PG. Signals use simple trend lines and a short‑term strength meter (RSI).

Big picture: when the market is trending up, it uses 3x stock funds for extra upside; when trends break, it hides in cash-like T‑bill ETFs. It checks simple trend lines on S&P 500 funds (SPY/VOO). In uptrends it buys either SPXL (3x S&P 500) or TQQQ (3x Nasdaq‑100)—whichever looks stronger on a short-term “hot/cold” meter (RSI). It also holds tiny slices of AVGO (chips), JNJ (healthcare), and PG (consumer staples). In downtrends it parks in BIL/SHV/SHY (very short Treasuries). If weakness deepens, it can even use SOXS (3x short semiconductors). A small sleeve (about 10%) rotates quickly between SPXL and TQQQ for bounces when the broader trend is still healthy.

Out-of-sample edge: annualized return ≈71.5% vs SPY ≈21.8%; Sharpe ≈2.27 vs 1.91; Calmar ≈8.84; max drawdown ≈8.1% (SPY ≈5.1%). Uptrend leverage with fast cash risk-off aims for bigger upside and disciplined downside control.
