Here’s a chart of the S&P 500 total return for the past 8 years:
The only conclusion my lizard brain can draw is that the stock market only goes up. In Daniel Kahneman’s terms from his great book Thinking Fast and Slow (my review here), my brain’s “System 2” knows that the stock market may crash in the future, but my automatic “System 1” is sure the stock market will keep going up forever.
As my human capital dwindles, I get closer to the age where I should be shifting some of my portfolio into safer investments than stocks. I’ve done this by building up a cash reserve, but perhaps it’s not as big as it should be at this point. It’s very hard to shake the feeling that I’m losing out by not having this cash in stocks right now. My System 2 has determined that I should have some fixed-income investments just in case stocks begin a large drop. But my System 1 resisted hitting the sell button.
Younger investors have bigger concerns. Those who have been investing for 8 years or less can’t be certain they have the stomach for the risk level of their portfolios. A huge risk for investors is that they will lose their nerve in a market downturn and sell out near the worst possible time. It’s hard to know what you can handle unless you have lived through a crash of the type that we had in 2008-2009 and back when the dot-com bubble burst.
We can be sure that a market crash will come eventually, but I have no idea when it will arrive. It’s possible that today’s stock level is the lowest it will ever be in the future. It’s also possible that stocks will get cut in half from today’s level. Most likely, we’ll get something in between.
Don’t let your lizard brain blind you to the very real possibility that stock prices will drop significantly from today’s levels. Try to invest your money with a mindset somewhere between fear and euphoria.
