Federal Reserve Governor Lorie Logan advocated for an immediate 25 basis point rate hike, citing persistent inflation pressures. Logan said inflation is not on track to sustainably return to the Fed's 2 percent target and that the central bank cannot rely on unexpected shocks to achieve its inflation goal. Taking modest action now, she said, would reduce the risk of more aggressive tightening later.

Her comments signal the Fed will prioritize price stability even as some market participants anticipate a pause. A higher-for-longer rate environment typically pressures growth stock valuations, as future earnings are discounted more heavily in investor models—yet the market reaction Thursday was sharply divided by name.

The Nasdaq gained 0.3 percent to 25,201. The Russell 2000, which tracks smaller companies more sensitive to borrowing costs, slipped 0.1 percent to 2,944. The S&P 500 was flat at 7,441 and the Dow Jones held at 52,194.

Amazon surged 15 percent to $270.83, defying broader rate concerns on strong business momentum. Microsoft gained 2.1 percent to $460.68, driven by its cloud and AI initiatives. Alphabet climbed 3.7 percent to $345.98, reflecting strength in digital advertising and cloud services. Nvidia rose 1.2 percent to $197.29, with AI-specific catalysts continuing to outweigh general rate pressure. Meta gained 1.2 percent to $545.41, supported by its advertising business and ongoing cost discipline.

Apple dropped 9.1 percent to $303.15, facing headwinds from consumer spending concerns and product cycle questions that higher rates could amplify. Tesla fell 1.1 percent to $305.40, weighed down by company-specific challenges and competitive pressure in the electric vehicle market.

The Federal Open Market Committee will announce its next policy decision Sept. 18.
