Stock Market Today, Oct. 28: Markets Edge Higher as Fed Holds Rates Steady

Stocks edged higher on October 28 as the Federal Reserve held rates steady, but the real action sat in single names. Vertiv (VRT) jumped 17% on AI infrastructure demand, while F5 (FFIV) plunged more than 20% on guidance concerns.

The S&P 500 rose 0.28%, the Nasdaq Composite gained 0.27%, and the Dow Jones added 0.19%. Energy stocks led the tape, while real estate and utilities declined.

Oracle (ORCL) climbed 11% after its investor day. Wingstop (WING) rose on an earnings beat. Those three gainers and one steep decliner show how heavily the session turned on company-specific news rather than the Fed hold itself.

After the close, Microsoft (MSFT) beat earnings expectations, while Alphabet missed revenue forecasts, which raised questions about whether AI spending can be sustained. Interpretation: the split reaction between the two megacaps suggests the market is no longer treating all AI-linked spending as equally rewarded, and the divergence between Vertiv's rally and F5's collapse points the same way.

Index moves under 0.3% mask that dispersion. Defensive sectors lagging while energy led also marks a tilt away from rate-sensitive groups, though the source offers no explanation for the rotation.
