Corporate Profits Climb to Fresh Highs: ETFs in Focus

The profit share is the real number to audit

The cleaner signal is not the dollar amount. It is profits as a share of the economy.

After-tax corporate profits reportedly reached 12.4% of U.S. GDP in the first quarter. That is described as the highest level since the second quarter of 2021, when profits peaked during the post-pandemic reopening. Measured against gross domestic income, profits represented 12.2%, cited as the strongest level since the early 1950s.

That matters for valuation work because margins are not an accounting footnote. They are a core input. A market multiple applied to elevated earnings is already making a margin assumption, whether the investor admits it or not.

The historical comparison is blunt. From 1950 through 2010, corporate profits as a share of GDP generally stayed below 10%. Over the past 16 years, that threshold has been exceeded more consistently, with only a brief pandemic-era interruption noted in the source material.

So the practical question is simple: are today’s earnings a new base, or an above-trend accrual investors are capitalizing at full value? The answer changes the implied intrinsic value of broad equity ETFs materially.

AI capex is being treated as a margin support

The cited report points to artificial intelligence and related infrastructure spending as a catalyst for the current profit cycle. Data centers and computing capacity are described, through Barclays commentary referenced in the article, as a “structural tailwind” for the broader economy.

That phrase should be handled carefully. A structural tailwind is not the same as free cash flow. Data centers require capital. Computing capacity has depreciation. Some beneficiaries will show operating leverage. Others will show capitalized costs today and impairment risk later if utilization disappoints.

Investors using ETF screens should separate three exposures.

First: companies selling into the infrastructure buildout. Their revenue may be closer to the spending cycle.

Second: companies financing or consuming that infrastructure. Their accounting may show expense timing, capital intensity, and cash conversion pressure.

Third: broad index holders. They own the profit pool without always seeing where the margin expansion is sourced.

The latest earnings season, according to the cited material, showed companies beating consensus estimates and offering reassuring economic reads despite elevated energy costs and other risks. S&P 500 earnings are expected to rise 23.7% in the June quarter from the prior year, on 11.4% higher revenue. That spread implies margin expansion. It also raises the hurdle for the next comparison period.

ETF selection: earnings weight is not a valuation shield

The ETF angle in the report centers on fundamentally weighted WisdomTree U.S. equity indexes covering large-cap, mid-cap, and small-cap earnings-generating companies. The cited funds charge 8 basis points for the large-cap exposure and 38 basis points for the mid-cap and small-cap exposures. Reported annual yields are 1.17%, 1.22%, and 1.16%, respectively.

That structure is useful, but not magic. Earnings-weighted products can reduce some market-cap concentration risk. They still rely on reported earnings. If aggregate profitability is elevated versus GDP and GDI, an earnings-weighted index may simply allocate more capital to companies currently harvesting peak margins.

There is also an energy variable. The source notes that a U.S.-Iran ceasefire could lower energy prices and support margins, while the United States Oil Fund LP has lost about 20% over the past month amid peace talks. Lower input costs can help corporate profits. But investors should not convert a commodity move into a permanent margin assumption without evidence in cash flows.

The audit checklist is narrow. Check whether ETF earnings exposure is concentrated in sectors where estimates are still being revised up. The report says only five of 16 Zacks sectors have seen June-quarter estimates rise since the quarter began, offsetting negative revisions in the other 11. Check whether revenue growth is doing the work, or whether margins are carrying the earnings line. Then haircut normalized earnings before assigning a broad-market multiple.

At current profit shares, the burden of proof sits with the buyer. The reported earnings base is strong. The valuation question is whether it is also sustainable.
