A daily strategy that flips between aggressive growth and defensive cash-like holdings: in healthy markets it owns leveraged stocks plus bonds, and in troubled markets it mostly waits for sharp selloffs to buy short-term rebounds.

This strategy asks one big question each day: “Does the market look healthy or stressed?” If the broad U.S. stock market has been in a meaningful slump over the past year, it switches to defense. In that mode, it mostly sits in BIL, a very short-term Treasury fund that behaves like cash. But if the Nasdaq 100 or S&P 500 has fallen more than 5% in 5 days, it may briefly buy a leveraged “bounce” fund (TQQQ for Nasdaq, UPRO for S&P 500) to try to catch a rebound—unless that rebound already happened in one big day, in which case it stays in BIL. If the market has not been in that larger slump, it uses a more aggressive growth mix: 55% split between UPRO and TQQQ, favoring whichever has been less jumpy recently, plus 45% in TMF, a leveraged long-term U.S. Treasury bond fund. If stocks get too shaky over the last 10 days, it steps out and parks in BIL.

Dynamic regime-switching strategy protects in downturns, seizes rebounds with measured leverage, and adds diversification beyond SPY. OOS return ~16% vs SPY ~18%, with risk-managed exposure.
