Don’t Fear the Froth. Stay Invested Even If Stocks Are Overvalued.

Maybe you have a pile of cash to invest, but you’re terrified of putting it into a US stock market near record highs. Or you’re worried about a market reversal and wondering if it’s time to cash out. If either scenario sounds familiar, do what banks and brokerages do when issuing their stock market forecasts: Bet on the market moving higher.

They’re likely to be right, even though the market is unmistakably frothy. The S&P 500 Index is coming off its best two years since the 1990s. At 25 times forward earnings, it was only more expensive just before the dot-com crash in 2000 and the tech wreck in 2022. The biggest seven companies in the S&P 500 by market value, which collectively account for more than a third of the index, are even more expensive, with a median P/E ratio of 31.

Add in the return of meme stocks, and the bewildering $75 billion leveraged bet on Bitcoin better known as MicroStrategy Inc., and it all looks like a classic prelude to a stock market smackdown.

Still, Wall Street strategists haven’t been deterred from forecasting fresh gains this year. That’s because, while valuations are a useful gauge of medium-term stock returns, they’re a terrible barometer of short-term market moves. A better guide for how the market is likely to perform in any given year is its past behavior. That history shows that the market grinds higher more often than it backtracks.
