Does Put/Call Ratio (Equity) actually work?

DEAD

No edge left once tested on a fair footing.

The claim

A CBOE sentiment/vol reading that times the market — CBOE / contrarian sentiment

What we did

Tested against Buy & hold SPY, same window (2012+), 2012-2026, both directions tested.

The result

Result: -0.04 dSharpe (vs buy-hold)

dSharpe -0.04 (IS -0.36 -> OOS +0.16); below the floor

Verdict

Equity put/call ratio: same verdict as the total -- noise as a standalone timing gate.

What the test did and did not do

Almost nobody publishing a backtest says which of these they did. We list the ones we failed as well as the ones we passed.

Tested 2026-06-23. The same treatment, applied to every other system, is on the test bench.
