Daily Tesla-focused momentum: hold TSLA when it’s strong but not overheated; otherwise hold SPY if the market is trending up, or sit in BIL (short‑term T‑bills) when conditions are weak.

Daily check. RSI is a 0–100 score of how fast price has risen vs fallen. - If TSLA (Tesla) 5‑day RSI > 65 and 15‑day RSI ≤ 85: own TSLA. - If 15‑day RSI > 85: move to BIL (short‑term T‑bills). - If 5‑day RSI ≤ 65: if SPY (S&P 500 ETF) is above its 200‑day average, own SPY; otherwise hold BIL.

Out-of-sample alpha ≈ 5.9% annually with a risk-aware TSLA momentum, SPY trend filter, and cash hedge. Sharpe ≈ 0.52; Calmar ≈ 0.46—supporting diversified, risk-controlled gains beyond plain SPY.
