A daily rule-based selector among NVDA, AMZN, MSFT, AAPL, and GOOGL using a volatility-vs-momentum test; if none pass, move to SHV. Rebalances daily with a single-asset focus and a safety fallback.

- Start with cash available for the day. - Check NVDA: calculate 5-day volatility (how wildly it moved) and 2-day RSI (momentum). - If volatility is greater than RSI, invest in NVDA for the day; otherwise move to the next stock. - If NVDA didn’t pass, repeat the same test for AMZN, then MSFT, then AAPL, then GOOGL, in that order. - If any one stock passes, allocate to that stock for the day (one-asset-at-a-time rule). - If none pass, invest in SHV (short-term U.S. Treasuries) as a safe fallback. - Rebalance daily, repeating the entire process the next trading day. - The intended outcome is to tilt toward a single, potentially stronger stock on days when its volatility exceeds its short-term momentum, but to default to safety if no stock meets the rule.
