Inspired by Johnson and So: Option-to-Stock Volume
NO EDGEUnusually heavy options trading relative to underlying-share trading can reveal negative private information when stock shorting is costly. The signal does not require classifying option trades as buys or sells.
How this run differs from the source: Long only, the low option-to-stock volume leg, monthly; the paper's result is a weekly low minus high spread.

|---|---|---|
| CAGR | 9.7% | 13.5% |
| Sharpe ratio | 0.64 | 0.94 |
| Max drawdown | -29.3% | -23.9% |
// GROWTH OF $1, LOG SCALE
Out-of-sample (from the split): CAGR 10.1% against 14.0% for the benchmark; Sharpe -- in-sample, 0.66 out-of-sample.
After 25 bps of trading costs: 5.6% a year. WITHIN RANDOM

// YEAR BY YEAR, LOSING YEARS IN RED
Losing years: 2018 (-12.2%), 2020 (-4.8%), 2022 (-12.5%). Each cell: the strategy, then the benchmark below it. * a part year.
// THE IDEA, AS PUBLISHED
Travis L. Johnson & Eric C. So (2012), The Option to Stock Volume Ratio and Future Returns, Journal of Financial Economics · 2012
- Weekly O/S = total option contract volume / share volume for each optionable stock
- Sort into deciles by O/S
- Long the lowest-O/S decile, short the highest
- Hold one week, then re-sort
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 2026-11-06 12:02 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
