Inspired by Novy-Marx: Profitable Value
TRADE-OFFCombine a conventional value screen with gross profitability, because profitable firms can be attractive even when their book-to-market alone does not identify them. The combination avoids treating all cheap firms as equivalent.
How this run differs from the source: An ROE floor, then a P/B rank; the paper ranks gross profits over assets plus book-to-market, long-short.

// THE IDEA, AS PUBLISHED
Robert Novy-Marx (2013), Journal of Financial Economics · 2013
- Calculate book-to-market using accounting book equity and market capitalization.
- Calculate gross profitability as gross profits divided by total assets.
- Select stocks that are relatively high in book-to-market and gross profitability, then rebalance on a stated schedule.
A real computation on the QuantGPT warehouse, walk-forward. A study across the whole market includes only part of the companies that later delisted from 1998 (survivors only before); a study on your own list of tickers is not affected. Gross returns, no costs except where stated. Past performance is not a promise. Findings, not advice. COMPUTED 2026-11-09 19:21 ON THE QUANTGPT WAREHOUSE. COMPANIES THAT LATER DELISTED ARE ONLY PARTLY IN THIS UNIVERSE (A FIX IS IN PROGRESS), SO THE RESULT LEANS TOWARD SURVIVORS. FUNDAMENTALS BY FILING DATE. NOT INVESTMENT ADVICE. PRIVACY
