Equity Factor Research
A guided tour through the empirical asset pricing literature — from classic factors to the replication crisis. Read the deep topic surveys, scan the factor reference below, then recompute it yourself in the replications.
Topic surveys
Low Volatility
Low-risk stocks earn as much or more than high-risk ones — the anomaly that most directly contradicts the CAPM, hiding in a noisy, over-tagged corner of the corpus.
Momentum
Past winners keep winning over 3–12 month horizons — one of finance's most robust anomalies, and one of its most crash-prone.
Quality
Profitable, well-run, conservatively-financed firms beat junk — the best-curated topic in the library, and the value investor's essential complement.
Reversal
Losers bounce back — over days (liquidity provision) and over years (overreaction). Two distinct effects often confused under one name.
Size
Small stocks once beat large — the premium that launched factor investing, then largely vanished, and now survives mainly as a conditioning variable.
The Factor Zoo & Replication Crisis
Hundreds of published factors, most of them fragile — the meta-literature on multiple testing, post-publication decay, and what actually survives. This is the lens the whole platform is built around.
Value
Cheap stocks beat expensive ones over the long run — the oldest cross-sectional premium, and the one whose recent decade-long drawdown has most tested investors' faith.
Surveys synthesize the paper-wiki library into a narrative per topic. The factor cards below are the quick reference.

Size
Structural
Small-cap stocks earn a premium — but it has nearly vanished.
Liquidity
Structural
Illiquid stocks earn a premium for being hard to trade.
The Factor Zoo & Replication Crisis
Structural
With 400+ published factors, most are likely false discoveries.
