Value (Stocks)
Buy cheap versus fundamentals or price, avoid expensive; value can underperform for years before mean reversion arrives.
Overview
Value (Stocks) sits in the Stocks chapter of the systematic catalog. On QUSXFI we treat it as a testable hypothesis: specify entries, exits, sizing, and costs—then ask whether edge survives out-of-sample scrutiny.
Discretionary traders often arrive at similar ideas intuitively; the quantitative version forces you to write the rule before you see the next bar. That discipline is what makes results reproducible—or exposes them as luck.
Based on the research catalog 151 Trading Strategies (Kakushadze & Serur, 2018), section 3.3. Educational summary—not a replication of the full formal definition.
