Dow and Nasdaq Rise as Fed Holds Rates; Labcorp Surges While Robinhood Slides on Earnings

Broad indices gained after the Fed held rates steady, with Labcorp posting an outsized surge and Robinhood dragging on a Q3 miss.

• Dow Jones and Nasdaq both gained Wednesday after Fed kept interest rates unchanged
• Labcorp shares surged sharply, driving healthcare outperformance in the session
• Robinhood fell on earnings miss, contrasting with broader market strength

Wednesday's session reinforced the Fed-as-market-driver dynamic that has defined equity behavior in 2026. The Federal Reserve's decision to maintain its target rate — anticipated but not guaranteed — removed the tail risk of a hawkish surprise, allowing risk assets to digest the heavy earnings calendar on its own merits. Indices trimmed early gains in the afternoon as participants evaluated a mixed bag of corporate results, but the net close remained positive, extending the market's resilience streak through earnings season.

Labcorp's surge stood out as the session's clearest single-stock story. The lab services company's results appear to have cleared a low bar set by prior negative estimate revisions, or potentially included a positive catalyst such as a guidance raise or operational improvement commentary. Healthcare names have been inconsistent performers in the back half of 2026, so Labcorp's session gain may attract rotation into the sector as investors search for beaten-down quality plays with near-term catalysts.

Robinhood's decline underscores the crypto-trading volume dependency that continues to weigh on the platform's earnings predictability. Falling crypto prices in Q3 compressed the transaction-based revenue that drives margin leverage for the business. While analysts retained generally constructive longer-term views, price target cuts signal near-term earnings uncertainty. The juxtaposition of Robinhood's miss against broad market gains illustrates how heterogeneous this earnings season has been at the individual stock level.
