Specifies the measurable entry characteristics, return-engine decomposition, base rates, drawdown path, sector regime, and consolidated targeting specifications observed at the moment of purchase for eventual 5x stocks. Descriptive research on what the data shows — not investment advice, not a live signal, not a screening ruleset.",
    "key_takeaways_sample": [
      "44% of U.S.-listed stocks achieve 5x from a prior trough at some point in their lifetime (trough-to-peak, not a fixed-window rate); any given 10-year window is ~5-15%.",
      "The median eventual 5x stock was cheap, small, and FCF-positive at entry: forward P/E ~11x, P/S 0.6x, P/B 1.1x, PEG 0.8, entry market cap ~$348M-$500M.",
      "FCF yield was the single most powerful empirical predictor across all model specifications; P/E was distortive and excluded from best models."
