A market-timing strategy that hides in cash during volatility spikes, chases the strongest big U.S. stocks in normal markets, and rotates into winning commodity and bond funds when conditions turn defensive.

This strategy first checks for a sudden spike in market fear using VIXY, a fund tied to stock-market volatility. If fear is extreme, it moves to BIL, a cash-like Treasury-bill fund. If fear is not extreme, it looks at TIP, an inflation-protected bond fund, as a clue about the interest-rate backdrop. If TIP has been rising over the last 60 days, the strategy goes into “risk-on” mode and buys the strongest recent performers from three groups: major S&P 500 stocks, major Nasdaq stocks, and major Dow stocks. It measures “strongest” by recent 20-day performance. Each group can also choose a defensive outsider if it is stronger than stocks: GLD (gold), BIL (cash-like T-bills), or USDU (a strong U.S. dollar fund). If TIP has not been rising, the strategy assumes a more defensive environment and shifts into “risk-off” mode. Then it splits money between commodity funds and bond funds, again buying only the recent winners from each list.

Out-of-sample, this strategy beats the S&P 500 on return (~24% vs ~19%), with similar/better risk-adjusted Sharpe (~1.22) and built-in volatility protection (cash during spikes). Drawdowns can be larger in rare periods (~24%).
