The S&P 500 is
Rising
  1. Puts 80% in the S&P 500 and 5% in each of the 4 strongest stocks.
  2. An AI reads the news and skips a risky pick.
  3. Calm and rising: the 80% moves to a 2× fund.
  4. The trend breaks. Everything moves to T-bills.
  5. The trend is back. It buys in again.

Hypothetical results from a simulation, not real trading, and nothing here is promised. $1,000, 2007 to 2026, after estimated trading costs, before taxes. The rules were written knowing how these years went, and the plan can trail the market for years. Limits of simulated results
