Quarterly sector-rotation: buy the two S&P 500 sectors that dropped the most over the last month, split money evenly, and hold for a quarter. A contrarian, mean‑reversion bet aiming to beat SPY with dividends reinvested.

Every quarter, it looks across 11 SPDR funds that each track one S&P 500 sector (tech, health care, energy, utilities, etc.). It ranks their last ~1 month performance (about 20 trading days) and buys the two that fell the most, 50/50, then holds for the quarter. “Cumulative return” here means total price change over that lookback, including dividends.

Quarterly sector-rotation: contrarian mean-reversion by buying two laggards. OOS, drawdown 14.8% vs 18.8% SPY; Calmar ~0.87. Return 12.8% vs 15.2% SPY, but steadier risk and dividends.
