Dimensional: A Transformed Investor’s Reaction to Coronavirus

The following commentary is provided by Dave Goetsch, executive producer of The Big Bang Theory.

The news is full of stories about the coronavirus. It’s scary. My 10-year-old son came home from school today worried about it. We don’t know how many people this will infect, nor how it will impact the world economy. This is exactly the kind of thing that would have freaked me out 20 years ago, spiked my blood pressure, and made me glad that all my money was in cash.

Back then, I would have seen this story as yet another piece of evidence for why I chose not to invest in stocks. Because I couldn’t predict the future. “Why invest when you don’t know what is going to happen tomorrow?” I would ask no one in particular.

It’s been 20 years since Y2K, 12 years since the financial crisis, 10 years since H1N1, and six years since the Ebola outbreak. Any money I might have invested right before Y2K (which hit on the heels of the Asian financial crisis of 1997) and left through all those ups and downs would have turned out fine—as long as I was widely diversified, with low costs.1

I don’t plan on touching the money I have in the market for 20 years. So when it’s 2040 and I look back at the coronavirus story of 2020, what will I think? Honestly, I don’t know. I gave up trying to predict the future a long time ago. But based on nearly 100 years of market data, I am choosing to be a long-term investor. I believe that the reason I get a good return over decades and not months is because markets are uncertain. If they weren’t, we’d call them a savings account. For me, riding out these ups and downs is not only one of the best ways to build a portfolio, it’s the most stress-free way of living.

I might be wrong, but decades of financial science suggest it's a sensible course, and that’s good enough for me.
