The market has been rocked. In the last two weeks (March 3-16, 2020), the S&P 500 has lost over 22% of its value. It’s the fastest 20% descent we’ve ever seen, and no one knows exactly where the bottom will be (or if we’ve already hit it). The market has moved in percentage multiples, both up and down, every day last week, an incredible level of volatility. The leading cause, which still feels surreal, is the propagating Covid-19 virus which has led to mass closings and increasing restrictions. Suffice it to say, it’s been a crazy couple of weeks.

In many ways, we’re in uncharted territory, which means we’ve got questions, like how are we supposed to respond to all of this? What’s the right thing to do when we’re confused about what’s happening? To add some clarity, I’ll offer up a few investing principles throughout this week.

Market timing doesn’t work.

• No one knows what the market will do tomorrow. Many make predictions, but no one really knows. Don’t try to guess where the bottom is, or when we’ll hit it, or when to pull money out of the market, or when to put the money back in. The market is efficient.
• Let’s say you really want to get out of the market because you don’t believe we’ve hit the bottom yet and you’re not interested in sticking around to find out. In order to successfully time the market you have to get two bets right: you have to get out of the market before it hits the bottom, and you have to get back in at or very near the bottom. The odds are not favorable.
• A market study conducted at the University of Michigan measured returns from 1963 through 2004 (a period of 42 years). They found that 96% of the positive returns over that period came from 0.85% of trading days (90 out of 10,573 total trading days).
• Another study done by A. Stotz Investment Research observed a 10 year period, from November 2005 through October 2015. After running the data through several simulations, they concluded that if you missed the 10 best market days over the specified 10 year period, you would stand to lose, on average, 66% of the gains you would have captured by staying in the market.
• When the market moves up, it moves up quickly. Whenever your money is on the sidelines, you risk missing some of the best days the market has to offer. So stay invested, don’t panic, and anticipate the rebound.
