S&P 500 Q3 profits projected to rise 29.5%: The numbers look impressive, but don't rush to applaud

A 29.5% increase would be eye-catching in any year. But break it down, and there are four questions to ask:

Who's driving the growth? The Magnificent Seven and the AI computing-power supply chain are the main drivers. Excluding mega-cap tech, growth is tepid across many sectors. A big jump in index profits doesn't mean every company is making money.

Is the growth coming from earnings—or cost savings? Some profits come from layoffs, cost cuts, and share buybacks that reduce the number of shares—not strong revenue expansion. Markets may assign a valuation to this kind of earnings, but not a premium.

How much is already priced in? If growth has already been priced in, the actual earnings report may turn into a “sell the news” event. We've seen this repeatedly in this cycle: companies beat expectations, yet their share prices still fall.

Are cash flows keeping pace? Meta's revenue grew 26%, but its free cash flow turned negative. Tesla's EPS beat expectations, but its operating profit was halved. Strong-looking income statements alongside weak cash flow statements are a hallmark of this AI capital-spending cycle.

In short: 29.5% is the headline; the underlying details are the story. Where the growth comes from, whether it translates into cash flow, and whether guidance can meet expectations will determine the quality of this earnings season. This is for tracking market signals only and does not constitute investment advice.#股票财报季
