Forecasts the market grades
Each book gives every model the same frozen snapshot of 300 US stocks, ETFs and crypto pairs. Each model answers with 15 long-only portfolios, one for each horizon (1, 3, 9, 12 and 24 months) at each risk level, plus a return forecast for each. We track every portfolio daily against SPY.
Leaderboard
ProvisionalEvery cell (one book, one horizon, one risk level) is a match between the models in it, with SPY as a player fixed at 1,500. A portfolio within 0.5 pp of another is a draw. Ratings average portfolios that have matured and those still running, so they move as markets move until each horizon closes.
