Is Equities Only Put/Call Ratio Warning of Extreme Complacency?

Sentiment can be a beautiful and useful contrarian indicator as markets tend to punish the majority: If everybody is bullish and has bought longs, then only selling is left. If everybody is bearish and has sold, then only buying is left.

One of the best direct measures of sentiment is the put/call ratio (P/C). It reflects “put your money where your mouth is,” as the ratio is based on the actual number/volume of puts and calls being bought
each day. Questionnaires and surveys about one’s point of view of the market on the other hand often only express an opinion and not necessarily one’s action.

Over the last three days, the Equites Only Put/Call ratio (OE-P/C) has been 0.49, 0.46 and 0.47 (source: https://markets.cboe.com/us/options/market_statistics/daily/). These are rather low readings. It
means for every put that was bought, more than two calls were bought. Hence, market participants were getting very bullish expecting the markets to move higher and higher. The chart below shows the last
time the EO-P/C dropped below 0.5 was in mid-November 2019 (dotted black vertical line). That was the first time it did this since the Dec. 24, 2018, low was put in place. The reward then was10% three
months later. The downside risk was almost 30% four months later. Not a good risk/reward ratio. Yet, here we are again at the same ratio, but now only two months after a historic low was put in, while back
in November the market had already rallied for almost one year. Are market participants getting too bullish?
