S&P 500 forward EPS hits $346.19

The story here is earnings — not just stock prices. Analysts’ profit estimates for the S&P 500 have kept moving up, and Yardeni’s forward operating EPS measure just hit a record $346.19. That matters because a lot of this spring rally only makes sense if profits really do keep growing fast. The market is paying up for that future, and the higher those expectations go, the less margin for error investors have. ### What is “forward EPS” actually measuring? It’s basically Wall Street’s rolling estimate of how much the companies in the S&P 500 will earn over the next 12 months. Not last quarter. Not this calendar year alone. A moving one-year window. That makes it one of the cleanest ways to see whether analysts think corporate America is getting stronger, and the macro backdrop is still improving even after a big run in stocks. ### Why does $346.19 matter so much? Because it helps explain why the index can stay near record highs without looking completely detached from fundamentals. If expected earnings are rising, prices can rise with them and the valuation math does not blow out as fast. Yardeni’s charts also show 2-year, not just a one-quarter pop. ### So is the market expensive or not? Yes — but not in the most extreme way bulls have seen lately. FactSet’s May 1 update put the S&P 500’s forward 12-month P/E at 20.9. That is above the 5-year average of 19.9 and the 10-year average of 18.9. But it is still below the 23.0 peak Yardeni highlighted for late 2025. So valuations are stretched versus history, just not at maximum stretch. ### Why do the Magnificent Seven matter here? Because they still distort the headline. Yardeni pegs the Magnificent Seven at a forward P/E of 26.1 — well above the broader index. That means part of the market’s valuation risk is concentrated in a handful of giant tech names. If those companies keep delivering, the premium can hold. It's like a building where a few columns carry too much weight. ### Is the earnings strength broadening out? More than before, yes. Yardeni’s latest note says mid-cap and small-cap forward earnings are also at record highs, and both groups still trade at lower forward multiples than the S&P 500 large caps. That matters because a rally driven only by seven mega-cap stocks is easier to dismiss. A rally with more breadth would do most of the lifting. ### What could break the story? The obvious risk is that the market has already priced in too much 2026 and 2027 optimism. Yardeni says analysts now expect S&P 500 earnings growth of 19.8% in 2026 and 17.5% in 2027. Those are big numbers. If margins compress, demand cools, or guidance weakens during the next few quarters, the market would have to absorb that disappointment through lower prices, lower multiples, or both. ### Why are investors still comfortable with that? Because the recent earnings tape has been strong enough to keep the benefit of the doubt alive. FactSet says the blended earnings growth rate for the first quarter has climbed to 27.1%, the strongest since late 2021 if it holds. That kind of upside surprise buys time for an expensive market. It does not remove the risk — but it explains why investors believe the forward numbers. ### Bottom line This rally is standing on a real earnings story, not just hope. But the market is also charging a premium for that story now. As long as forward EPS keeps rising, stocks can keep working. If the earnings revisions stall, the valuation cushion is thin.
