We take the volume of put options and divide it by the volume of call options.&nbsp; Simple arithmetic is easy for people to understand.&nbsp; Interpreting that simple ratio is quite another thing, however.<\/p>\n\n\n\n<p>Many of us tend to look at the put\/call ratio as a contrary indicator.&nbsp; The logic is that when people are flocking to puts, the risks that they are attempting to either hedge or profit from are largely behind us.&nbsp; Taken another way, a surge of put buying is believed to signal the latter phases of a downdraft rather than its start.&nbsp; At some level that is dismissive of the market\u2019s ability to properly foresee events.&nbsp; In theory, an omniscient &#8212; or simply efficient &#8212; market should experience an influx of put buying <em>before<\/em> a downward move, not after.&nbsp;&nbsp; In reality though, we tend to see measures like the Cboe Volatility Index (VIX) peak just around the culmination of a sell-off.&nbsp; Too many investors have a nasty habit of closing the proverbial barn door just after the horse has left.<\/p>\n\n\n\n<p>Another issue with the put\/call ratio is how to construct it.&nbsp; We can use single-stock and ETF options volumes or index options volumes.&nbsp; We can focus on a single exchange or accumulate the volumes from across all 16 US options exchanges<a href=\"#_edn1\" id=\"_ednref1\">[i]<\/a>.&nbsp; The choices can be overwhelming.<\/p>\n\n\n\n<p>I prefer to use a 21-day moving average of the put\/call volumes across all exchanges.&nbsp; A moving average is very helpful, because the daily readings can be quite noisy.&nbsp; There are roughly 21 trading days in a month, so I find that to be a useful way to discern intermediate-length trends.&nbsp; And I prefer to use all-exchange volume because it seems unnecessarily restrictive to focus on one exchange when there are so many venues.&nbsp; There is a rationale for using Cboe as a proxy for index activity because of their exclusive contracts with S&amp;P Global (SPGI), but much less for a broad look at options activity.<\/p>\n\n\n\n<p>A reporter whom I respect contacted me yesterday, asking for comment about why the 20-day moving average of the CBOE put\/call ratio was at levels not seen since April 2020.&nbsp; I was glad for the question, because it\u2019s a phenomenon I\u2019ve been noticing in my work, as evident in the graph below:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><em>All Exchange Put\/Call Ratio (OPCVTPCR, white), with 21-day Moving Average (magenta) and S&amp;P 500 Index (orange), 2020-present<\/em><\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"624\" height=\"317\" data-src=\"\/campus\/wp-content\/uploads\/sites\/2\/2022\/09\/Picture1-8.png\" alt=\"All Exchange Put\/Call Ratio (OPCVTPCR, white), with 21-day Moving Average (magenta) and S&amp;P 500 Index (orange), 2020-present\" class=\"wp-image-158161 lazyload\" data-srcset=\"https:\/\/ibkrcampus.com\/campus\/wp-content\/uploads\/sites\/2\/2022\/09\/Picture1-8.png 624w, https:\/\/ibkrcampus.com\/campus\/wp-content\/uploads\/sites\/2\/2022\/09\/Picture1-8-300x152.png 300w\" data-sizes=\"(max-width: 624px) 100vw, 624px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 624px;
