About
Daily mean‑reversion in China and U.S. biotech using 3x bull/bear ETFs. If no recent extreme, it buys a leveraged volatility fund (UVXY) when markets look overheated, otherwise holds T‑bills (BIL). Very volatile and high risk.
The portfolio runs two sleeves: China stocks and U.S. biotech. Each day, if either area moved ~±10% over 5 days, it bets on a short‑term snap‑back: after a down day it buys the 3x bull fund (YINN or LABU); after an up day it buys the 3x bear (YANG or LABD). If there’s no recent extreme, it either buys UVXY—a leveraged “fear/volatility” fund—when a 0–100 heat meter (RSI) shows the U.S. market is overheated, or it parks in T‑bills (BIL). Very high risk.
Out-of-sample edge: strong risk-adjusted return with low beta and diversification. oos Sharpe ~0.79, Calmar ~0.80, 16.8% annualized vs SPY 19.4%, plus UVXY hedges in overheated markets—an appealing ballast to the S&P 500.
