This time 2 years ago, we were still riding high on the post-pandemic surge, and analysts were expecting the S&P could break 5,000. This time last year, we were still in what felt like the 2022 doldrums and analysts were predicting a recession. This time 3 months ago, people were declaring inflation was whipped. And then a few days ago, CPI and PPI came in hot.

I’ve written before about how the Efficient Market Hypothesis may imply that there is *no* correlation between analyst opinion and the stock market. Analysts are just as likely to be wrong as right, but people only remember the examples which agree with their biases. On the other hand, I read an article recently (I’m sorry I cannot find it to link) arguing that analyst opinion is in fact *anti*-correlated. That is, the Short Cramer ETF is correct, and analysts are so stupid you should do the opposite of what they say.

Speaking of, the Short Cramer ETF “SJIM” is down about 20% from when it began. But no matter, should you do the opposite of what analysts say or is that as irrational as following their advice?

One argument is that analysts are inherently *backward-looking*, they generally assume trends will continue forever. Some are perma-bulls or perma-bears, but on average when the market is down analysts predict a down year, and when it’s up they predict an up year. In this case, if the market is a random walk then it’s very unlikely to simply continue it’s current trend, thus an analyst is more likely to be wrong than right.

On the other hand, shouldn’t wisdom of the crowds have an affect? On the aggregate, many gamblers who bet on real world events (either sports of politics) are betting on what they *want* to happen, and many have no real knowledge whatsoever. Yet Nate Silver and others have argued that betting markets are often more accurate than not, whether it’s politics, sports or what have you. Some how, a million idiots adds up to something better than our smartest mind.

If that’s the case why don’t all the analysts of the market add up to something smart?

It just reminds me to be humble, because all too often I’ve seen people caught out badly by a trend. The late 2023 “inflation is beaten, start thanking Joe Biden” narrative won’t seem as smart if inflation stays persistently hot, any more than the “recession around the corner” narrative of 2023. Overconfidence when you really know nothing is the hallmark of an analyst, and maybe that’s why they’re so often wrong.
