The put/call ratio for 99 stocks and ETFs, nearest expiry.

Where traders lean hardest

Single stocks with the most puts per call and the most calls per put for their nearest expiry. Index and sector funds are left out of these two lists because their puts are mostly insurance, which keeps their ratio high as a matter of course.

How the ratio on this page is worked out

Each figure covers one expiry date, the nearest one, not every expiry added together, so it can differ from the all-expiry ratios some sites publish.

• It blends two versions: 70% today's put volume divided by call volume, and 30% open puts divided by open calls (open interest). Volume shows what traders are doing today; open interest shows what they are holding.
• When there is no volume data for that expiry, the figure is the open interest ratio alone.
• "n/a" means we could not work it out for that expiry, for example because no calls were traded or open. We never show a made-up number.

How to read it

For single stocks, below about 0.7 means traders favour calls and above about 1.2 means they favour puts. Extremes are sometimes read the other way, as a sign the crowd has gone too far. For index funds like SPY and QQQ, a ratio above 1 is normal because investors buy puts to insure the stocks they own, so it says little about direction. Either way it is a mood reading, not a forecast. Read it next to the expected move, which tells you how big a move the options are pricing in.
