S&P 500 Holds Steady Near Record Highs, Powered by Mega-Cap Momentum

The S&P 500 spent Wednesday hovering just shy of its all-time high—less than 1% away at the open—and despite a lack of upward momentum, it managed to hold firm by the closing bell. With no strong catalyst to push stocks to new records, the broader market experienced a bout of profit-taking. Still, a few heavyweight tech names once again proved enough to steady the major indices.

Leading the charge were NVIDIA (+4.3%), Alphabet (+2.2%), Apple (+0.6%), and Microsoft (+0.4%). Together, these four mega-caps boast a combined market capitalization of roughly $12.2 trillion, a scale large enough to offset weakness elsewhere—most notably in FedEx, which tumbled 3.3% after a disappointing earnings report and downbeat guidance.

The outperformance of these giants also helped counterbalance losses in Tesla, which dropped 3.8% on news that its European sales fell nearly 28% year-over-year in May. However, market breadth revealed a more cautious tone. Declining stocks outpaced advancers by more than 2-to-1 on the NYSE and 7-to-4 on the Nasdaq, underscoring a narrow leadership structure.

Smaller and mid-sized companies fared worse. The Russell 2000 lost 1.2%, the S&P Midcap 400 fell 0.8%, and the equal-weighted S&P 500 dropped 0.7%, signaling broad-based selling beneath the surface. Eight of the eleven S&P sectors ended in the red, with losses ranging from 0.4% in financials to 2.5% in real estate.

Despite the general weakness, the Nasdaq 100 managed to set another all-time high, buoyed by strength in tech and communications. The information technology sector climbed 1.2%, and communication services added 0.5%, thanks largely to mega-cap strength. Health care also inched up 0.1%, while the Philadelphia Semiconductor Index gained 1.0%, bringing its quarterly gain to a remarkable 28.6%.

On the macro front, there were few fresh headlines to steer market direction. Fed Chair Jerome Powell appeared before the Senate Banking Committee but avoided making any notable comments on rate policy. Elsewhere, NATO reaffirmed its 5% defense spending commitment, and there were no significant developments on the Israel–Iran front.

One notable item came from the Fed’s proposal to ease the supplemental leverage ratio for globally systemically important banks (GSIBs), a move that had been widely expected. This, combined with a weak May new home sales report and a lukewarm reception for a $70 billion 5-year Treasury auction, lent some support to bond prices. Treasury yields dipped modestly across the curve.

The U.S. portfolio FTinvest 11 extended its decline today, with weakness spreading across nearly all of its components. The index fell 1.44%, closing at 756.37—marking one of its sharpest daily drops in recent weeks. Today’s decline reflects a broad-based pullback, as market sentiment turned cautious and few holdings managed to buck the negative trend. With downside pressure mounting, the coming sessions will be key in determining whether the portfolio can stabilize or if more defensive positioning is warranted.
