A daily, rule-based strategy that toggles between a defensive 6-ETF mix (DIA, VIG, VYM, VPU, BIL, GLD) and a bullish 2-ETF leveraged play (UPRO, TQQQ) based on whether 60-day returns of BIL beat SPY. It rebalances to equal weights each day, using straightforward, non-derivative-heavy exposure.

- Every day, the strategy decides which group of ETFs to hold. - It computes the 60-day cumulative return for BIL and for SPY. If BIL’s 60-day return is greater than or equal to SPY’s 60-day return, it treats the market as risk-off and buys a defensive mix: DIA, VIG, VYM, VPU, BIL, and GLD, allocating equal money to each. - If SPY’s 60-day return is higher, it treats the market as risk-on and buys two leveraged growth ETFs: UPRO (3x S&P 500) and TQQQ (3x Nasdaq 100), allocating equal money to each. - Rebalancing occurs daily, so the positions are reset to equal weights within the chosen group each day. - No ETFs outside these two groups are used unless you extend the rules; the strategy aims to keep holdings simple and transparent.

Out-of-sample annualized return ~41% vs SPY ~21%; Calmar ~1.26. A daily, rule-based switch between defensive assets and leveraged growth captures upside in rallies with disciplined risk management for growth-focused investors.
