Market Ethos
August 14, 2023.
Investor sentiment is a pendulum that swings back and forth between extreme optimism and extreme pessimism and never sits still. Every individual stock has its own little pendulum. At times investors rapaciously bid up shares, believing prices will continue driving to irrational levels. In contrast, when the pendulum swings the other way, investors want nothing to do with the stock market. Selling pressure drives prices to irrational levels as well, with the stock languishing and few motivated buyers in sight. Sentiment shifts are subtle at first, but an increase in momentum can quickly escalate. These shifts typically occur at the extremes; the fear of missing out kicks in when the market goes higher and makes investors want to buy. When it moves lower, it makes you want to sell because you don’t want to lose what you have. Buy high and sell low isn’t how it’s supposed to work, but that’s how our brains and emotions operate. Unfortunately, the market and your brain never scream at you to do the right thing, only the wrong thing. It’s why gauging current market sentiment can help investors understand and hopefully be prepared for those important shifts.
At an aggregate level, market sentiment can be measured in many ways. One of our favourites is the AAII Investor Sentiment Survey. The American Association of Individual Investors has been doing a simple weekly survey since 1987. The long history makes it an ideal data set to understand the relationship between sentiment and stock returns. The most recent reading shows that bullish sentiment is unusually high for the second time in three weeks, while bearish sentiment is below average for the eighth time in 10 weeks. Bullish sentiment has risen extremely fast the past couple of months, as detailed in the chart below, and while not at historical extremes, the spread between the bulls and bears moved into the ‘sell zone’ a few weeks ago. When the spread is above 20, it means that the bulls are in control and the pendulum has swung nearly to its limits. On the other hand, below -20 is the ‘buy zone’ where bearish sentiment is extreme and future returns are more promising.
So, what does this mean for investors? The chart below shows S&P 500 future returns following sentiment extremes. This clearly shows the benefits of buying low, with future 3-month returns at bearish sentiment extremes nearly four times higher compared to future returns when sentiment is extremely bullish. The most recent AAII release on August 10 has the spread falling back under 20, so the bullish sentiment has backed off slightly but has spent the past three weeks in the sell zone.
There are many ways to measure sentiment. One other noteworthy method is gauging how pervasive the positive sentiment is. While also a breadth measure, looking at the percent of members above their 50-day moving averages helps with this. It’s now turning back down after recently reaching the year’s highest level. While the S&P 500 is only down 2% from recent highs, 25% of companies within the index have fallen below their 50-day moving averages. This warrants some concern as this type of reversal has a good track record of identifying decent-sized pullbacks.
Beware the pumpkin spice
We’re nearing that time of year. By the end of the month, we’ll be bombarded by pumpkin spice everything. We blame Starbucks and influencers for this trend. Pumpkin spice has been as synonymous with fall as crisp autumn air and changing leaves. Apologies for jumping the gun, but August is almost half over and September is just around the corner.
Besides stretched investor sentiment, one other potential risk on the horizon for investors is seasonality – whether real or perceived, seasonality and sentiment are inexorably intertwined. Bit of a chicken and egg situation, but market seasonality assumes some sort of repeating sentimental shift in risk aversion, which in turn affects prices. Seasonality in stock returns has been known for decades. As the chart below shows, average monthly stock returns are negative in September and extremely positive around the turn of the year. Going back to 1951, the average return in September in Canada is -1.2%, with just 42% of the months positive. December is the highest, with an average of 1.7% with a win rate of 82%. Now these are averages, so it’s not a guaranteed exploitable trading event, but the numbers are on your side to tread carefully and take some risk off the table. Anyone surprised if the market were to sell off in the next month or so is NOT a student of market history.
We’ve seen some research that attempts to attribute seasonality to Seasonal Affective Disorder (SAD). We’re certainly sad to see summer go, but the sad reality is that in September, trading desks are back at full staff, and real work gets done. More often than not, it seems it’s a time of profit-taking, de-risking, and of course, a pumpkin spice latte.
Final thoughts
Sentiment is not the be-all and end-all of investing … if only it were that easy. But it is important, especially at extremes. The big question is whether or not we’re in a new bull market or if is this just the mother of all bear market rallies. The market loves the soft-landing narrative and given how well markets have performed the past few months, it’s really taken hold. Looking at the global economic data, there is still enough ambiguity to not rule it out. For an investor, if you believe in the soft landing, it makes sense to rush into risk assets now before the data plays out. But this is simply greed taking hold; this still could be a big bear market trap. Given stretched sentiment and heading into the seasonal weak season for markets, we caution investors not to join the herd.
