There’s a consistent pattern that tends to occur with market sentiment and it happened again this week.

Here’s the pattern: The market has a nice uptrend that usually lasts 6-12 weeks. The rally usually stalls when the market and its leading stocks get a little too extended technically, and when bullishness increases based on many sentiment measures. We then see a decline until sentiment reaches extreme bearish levels or drops very suddenly. After stabilizing, the market tends to grind back up and embarrass all the people who reduced exposure, loaded up on put options, or turned “end of the world” bearish.

The reason I pay so much attention to sentiment is that the market is never obvious and tends to fool the majority. The difficult part about interpreting sentiment is that sometimes this jump in bearishness happens quickly, as it did this week, and other times it takes a while. For example, in the fall of 2018 market participants got very complacent after being conditioned to buy the dip for so long. The market kept sliding the entire quarter until sentiment reached extreme bearish levels near the end of December 2018.

Here are some examples of the sentiment measures that quickly turned bearish after this recent decline:

What’s more fascinating to me is WHY this happens? There are several possible reasons. 1) Many people are becoming macro economists and over-thinking fundamentals rather than focusing on what the big institutions are doing. After all, they control the market, not the economists.

2) Many feel this recovery has gone on for too long and will end any day now, so they always have one foot out the door. Keep in mind the economy has recovered slowly and steadily for the past 10 years, but the stock market has seen 20% corrections in 2011, 2018, and a brutal bear market beneath the surface from mid-2015 through mid-2016.

3) I hate to bring up politics but many people can’t stand President Trump and want the stock market to fail in order to see him not get re-elected. As Warren Buffett says: “If you mix politics with your investment decisions you’re making a big mistake.”
