The S&P 500 has gained over 20% this year as the bull market continues. Investors have been optimistic, anticipating lower interest rates and rushing to invest in high-growth AI stocks. These stocks have led the market, climbing by double and triple-digit percentages since the start of 2024.

Other growth stocks have also taken off as investors bet on better times ahead. However, this growth has made stocks more expensive by common valuation metrics. If you buy now, you may be getting less of a bargain.

The Cyclically Adjusted Price-to-Earnings (CAPE) ratio, which measures a stock’s price against the company’s inflation-adjusted earnings over a 10-year period, sits at about 35 today for the S&P 500. This is higher than most periods in the past 67 years. Over the past 20 years, the average reading was in the mid-20s.

Despite the market being expensive overall, not every stock is overpriced. There are still stocks trading at relatively attractive multiples. It’s important to stay in the market throughout various cycles and look at stocks individually to avoid missing opportunities.

Even if the market pulls back and a recently bought stock declines, it shouldn’t spell disaster for a long-term portfolio.

Short-term gains or losses won’t make much difference to overall returns if you hold on for five or ten years or more.

Considering the S&P 500 Shiller CAPE ratio, investors should remain vigilant when deciding which stocks to buy. Quality companies that have become too pricey may be ones to add to a watch list, in hopes of catching them at a more reasonable valuation in the future. Meanwhile, continue investing, as there are great opportunities out there.

The earlier you get in on these stories, the more you’ll benefit as they progress over time. Free cash flow yield, which measures the cash left over after a company supports its operations and maintains or invests further in its business, also points to a stock market that is not cheap, though it has been more expensive at times in the past. Technology stocks are priced at an even lower free cash flow yield, reflecting optimism about the future of many of these companies and their superior fundamentals.

Profit margins, which measure the percentage of top-line sales that become bottom-line profits, are elevated relative to history. The profit margins for the technology sector are close to double the market as a whole, helping explain the premium valuation assigned by the lower free cash flow yield. The risk of eventual disappointment is higher in stocks when valuations are above average and forecasts are rosy.

For long-term investors who can withstand the inevitable volatility, the discussion of overvaluation is moot since stocks have provided the highest after-inflation returns of any asset class despite the ups and downs throughout history. Investors should be mindful of their asset allocation and risk tolerance, considering rebalancing to an appropriate risk level after the robust stock gains, especially in light of possible higher capital gains tax rates next year. Owning some high-quality and less economically sensitive defensive stocks serves as a protective measure.
