About
A two-part stock/bond strategy that owns the S&P 500 when the market trend looks healthy, but shifts part of the portfolio into long-term Treasury bonds—or cash—when conditions weaken or get too volatile.
This strategy splits money into two parts and checks the U.S. stock market each day using SPY, a fund that tracks the S&P 500.
Part 1 follows the market’s trend: if the longer-term trend looks healthy, it buys SPY. If not, it shifts defensively—either into long-term U.S. Treasury bonds (TLT) or sometimes cash.
Part 2 watches how wild recent market moves have been. If stocks get too jumpy, it moves that portion into TLT.
Defensive trend mix: when stocks look risky, shift to long-term Treasuries or cash. Seeks steadier risk-adjusted returns with ~11.8% out-of-sample annualized return and ~0.77 Sharpe vs SPY’s ~0.88, with drawdowns near SPY’s ~18.8%.
