The S&P 500's Earning Yield Reaches a Critical Juncture

Ah, the ever-evolving dance of the financial markets! It seems there’s always something new to ponder, a fresh data point to dissect, especially when it comes to the venerable S&P 500. Recently, a particular metric has caught the eye of many market watchers, and for good reason: the S&P 500’s trailing 12-month earnings yield has just crossed the crucial 5% threshold once more. If you've been keeping tabs on market valuations, you'll know why this is quite the talking point.

Think of the earnings yield as a sort of "return on investment" that stocks offer, based purely on their earnings. It’s essentially the inverse of the much-discussed price-to-earnings (P/E) ratio – instead of how much you pay for a dollar of earnings, it tells you how many dollars of earnings you get for a dollar you invest. As of May 31, 2024, this yield hit a rather respectable 5.06%. Now, that’s the highest it’s been since the middle of November last year, which, let's be honest, feels like a lifetime ago in market terms, doesn't it?

So, why the buzz around 5%? Well, it all comes down to comparison. For years, investors have been weighing up the allure of equities against the steady, albeit often lower, returns from bonds. The gold standard for comparison here is often the 10-year U.S. Treasury yield. At the time this 5% earnings yield emerged, the 10-year Treasury was hovering around 4.5%. Suddenly, the S&P 500's earnings yield looks rather competitive, offering a slight premium over the "risk-free" rate.

This isn't just a fleeting moment; it marks a significant shift from previous periods. Remember those "TINA" (There Is No Alternative) days when bond yields were practically non-existent, making stocks the undisputed king? And then came the rapid rise in interest rates, which saw bond yields soar, making them a serious contender again, sometimes even surpassing equity yields. To see the S&P 500’s earnings yield comfortably above 5% again, and crucially, above the 10-year Treasury, suggests a potential re-evaluation of how attractive stocks are right now. It provides a bit more breathing room, doesn't it?

Historically, a higher earnings yield compared to bond yields has often signaled that stocks are looking relatively inexpensive or, at the very least, offering a compelling return for the risk involved. While the S&P 500’s forward earnings yield – which looks at anticipated earnings over the next year – is even higher, sitting around 5.56%, this trailing metric gives us a concrete look at what's actually been achieved. It's a snapshot of the present reality, suggesting that the broader market might not be as frothy as some perpetually fear.

Of course, this doesn't mean it's time to throw caution to the wind and dive headfirst into every stock. Far from it. The market is a complex beast, influenced by inflation, interest rate expectations, geopolitical events, and company-specific fundamentals. However, seeing the aggregate earnings yield for the S&P 500 reclaim this level is certainly a data point that adds a layer of reassurance for long-term investors. It implies that, on a broad earnings basis, the market is offering a more robust yield than we’ve seen in quite some time, making the current valuation picture a tad more palatable.
