A no-leverage, daily-rebalanced sector-rotation system with a small crypto overlay and a volatility hedge trigger, using max-drawdown and short-term momentum signals to pick among a few broad assets while mostly staying in cash.

- Start with mostly cash (about 90%) and keep a 10% slot for potential exposure (including crypto). - Daily rebalance: evaluate signals and decide which asset to hold in that 10% slot for the day. - Momentum hedge: compute a short-term momentum signal on TQQQ (RSI over 10 days). If RSI > 79, move into VXX (volatility-based hedge) instead of chasing sector exposure. - Sector check (in order): QQQ, XLE, XME, GLD. For each, measure the biggest price drop from a peak in the last ~20 days (max drawdown). If that drawdown is less than 5%, allocate to that sector ETF and stop checking further (that sector is chosen for the day). - If none of the sector checks pass the drawdown test, shift into SHY (short-term Treasuries) as a safe-haven choice. - Crypto block: separately, if GBTC is above its 50-day moving average (i.e., price > EMA50), allocate 10% to GBTC; if not, keep that 10% slot available for the sector rules above. - No leverage anywhere, and all rebalances are daily. - Purpose: test whether using a max-drawdown filter to rotate among a small set of broad assets can beat the market while limiting downside. - Practical note for laymen: VXX is a volatility instrument and can behave very differently from stocks; GBTC is a crypto-linked vehicle; QQQ, XLE, XME, GLD, SHY are common ETFs representing tech, energy, materials, gold, and short-term bonds respectively.

Out-of-sample edge: 21.43% annualized vs 18.33%; max drawdown 11.84% vs 18.76%; Sharpe 1.23 vs 1.06; Calmar 1.81. Cash-centric, no-leverage rotation with a small crypto overlay and risk hedges aiming for higher, steadier returns.
