Headline: MARKET MELTDOWN
Headline: HISTORIC PLUNGE
Maybe those should read MARKET SALE and HISTORIC BUYING OPPORTUNITY.
Except those would be just as silly. Today's movement isn't big enough to motivate me to sell, if I think it's going down, or to motivate me to buy, if I think it's going back up. It's just another day of volatility, and it will all come out in the wash down the road.
Stay the course, people. Invest regularly. Rebalance periodically. Minimize fees. Retire when ready and try to think about more important things.
