Framler score is a 0–100 composite number summarising how attractive a stock looks across 13 academic factor families — quality, value, momentum, post-earnings drift, accruals, insider flow, and others. 50 means neutral; above 60 is the buy bucket; below 40 is the sell bucket. The number is relative to the live universe, not absolute.
Each of the 13 factor families (quality, value, momentum, etc.) scores the stock 0-100. We z-score them across the universe, weight each by its prior reliability, and combine into one composite. 50 = neutral / average. 65+ = strong-buy region (top decile). Below 35 = strong-sell region. The number does not say "this stock will go up by X%" — it says "this stock currently looks more attractive than this percent of comparable names".
