In a scenario such as this, let inertia work for you. One way to reduce the impulse to sell is to remove the stimulus: stop looking at your account balance. This is good advice even during normal times. There is no reason to look at your investment balances more than once a quarter or even once a year when your goal is years or decades in the future. Long-term investing can be really boring. You can go for years without doing anything and be wildly successful. The temptation is to futz around with your investments, buy a little of this, sell a little of that. Avoid tinkering just to “do something.” This is why having your portfolio on your phone is a bad idea. Apps such as Robinhood, which “gamify” trading, can be dangerous to long-term investing success.
