About
Cash-heavy crash-avoider: most sits in T-bills; a 30% sleeve owns SPY in uptrends, otherwise bonds or oversold tech. In deep Nasdaq selloffs it hedges/shorts and, when momentum turns, rotates to Nasdaq/semis (incl. 2x funds).
Most stays in T-bills (SHV). About 30% is tactical:
- If the S&P 500 fund (SPY) is in an uptrend (price above long-term averages), it holds SPY.
- Otherwise it holds 3–7yr Treasuries (IEI) or, if the Nasdaq-100 (QQQ) is very oversold (low RSI), it buys the Tech sector fund (XLK).
- In deep Nasdaq declines (~−20%/yr), it hedges/shorts QQQ (PSQ/QID). If momentum improves, it goes long QQQ or Semiconductors, incl. some 2x funds (SMH/QLD/USD). It can also use Consumer Staples (XLP). RSI = short-term “heat”; moving averages = trend.
Out-of-sample edge: higher risk-adjusted return and smaller drawdowns vs the S&P 500. OOS Sharpe 1.75 vs 1.43; est. 28.1% annual return vs 22.6%; max drawdown 10.2% vs 18.8%; Calmar 2.76. Cash-heavy, trend-following with selective tech exposure.
