The 7 biggest investing lessons of 2020

In This Article:

In any eventful year, there are opportunities to learn. While you can easily finish with the wrong takeaways, 2020 was instructive, if you’re willing to listen to it. In the events of this year, the jagged teeth of the market, the rising cases of coronavirus, the declining jobs, and the soaring S&P 500 (^GSPC), some important takeaways emerge.

Nobody can see the future

If there’s one overarching lesson of the year, it’s that no one knows what’s going to happen. Certainty has frequently been rewarded with a cruel sense of humor throughout history, and this year saw everything change in stark ways that everybody knows all too well.

Back in March, economists, politicians, and investors laid out scenarios of the potential impact of the coronavirus on the economy, public health, and the stock market — as well as how society might have to respond. The median forecast was not accurate; the median 2020 S&P 500 outlook was for just a 2.7% gain.

Some S&P 500 predictions were decent-ish: Piper Jaffray saw the S&P 500 at 3,600. Fundstrat and BTIG were the next most bullish at 3,450. Goldman Sachs guessed 3,400. UBS and Morgan Stanley guessed 3,000. But of course, nobody’s estimates factored in a global pandemic.

Forecasts are easy to pick on, and at their best, they’re not meant to be crystal balls but tools to use like any other. Forecasts can be useful in a “if things continue on this path, this is where we think we’ll be” manner, but when a global pandemic is unfolding, their utility is questionable. And to their credit, many forecasters withdrew guidance.

This humility looks extremely good in retrospect.

Imagine if someone had a crystal ball, and the knowledge that the country would be slammed by well over 300,000 dead and almost 20 million cases by year end. Would they still have expected the S&P 500 to be up almost 15% after dropping over 30%? Probably not.

This isn’t to say that predicting is always futile. A lot of people predicted the coronavirus would come and cause a huge problem in the U.S. Those predictions were useful, not necessarily as measures of probability but first and foremost, as warnings about icebergs ahead.

Unthinkable things can happen

Back in February after watching the coronavirus emerge and spread in China, there’s no doubt some people were sounding the alarm that this could cause a huge global problem.

But as people like Mohamed El-Erian warned investors, stock prices continued to suggest a collective denial, peaking in late February long after the virus had reached our shores and began spreading.
