These figures describe the backtests people chose to run here, so they reflect what visitors are curious about, not the market or what anyone actually invests. “DCA beat a lump sum” is about the start dates people picked, which tend to cluster around well-known moments. Past performance does not predict future results and nothing here is financial advice. Only user-initiated backtests are included, and numbers refresh about once an hour.
