About this strategy

After the last close of each month, the strategy scores eight ETFs (US and global stocks, real estate, gold, and long and intermediate Treasuries) by recent momentum relative to their own volatility. When the inflation-protected Treasury canary (TIP) is trending up, it holds the four top scorers in equal weights. When it is not, it holds the stronger of intermediate Treasuries and T-bills, all of the portfolio. Long-only, fully invested, no leverage. The trade is made at the close of the next trading day.

The exact rules stay private. Every signal comes from locked code with no manual override.
