Market Summary: Dow Holds Weekly Gain Amid Hawkish Fed Signals

Key Market Movements

U.S. equities closed lower Friday, with the S&P 500 down 0.26% to 7,711.05 and Nasdaq falling 0.53% to 26,400.56. The Dow Jones slipped 0.02% to 53,558.38 but retained a 0.5% weekly gain. The S&P 500 and Nasdaq declined 0.5% and 0.9% for the week, respectively.

Fed Policy Shift

Federal Reserve Chair Kevin Warsh's comments at Jackson Hole drove market volatility. Warning that recent inflation data showed insufficient improvement, Warsh emphasized the Fed needs confidence that inflation is moving toward its 2% target at "sufficient speed." His hawkish stance caused September rate hike probability to surge to 57% from 35.4% the previous day, according to CME's FedWatch tool. Short-term Treasury yields rose following the remarks.

Sector Performance

Technology/Semiconductors: Chip stocks retreated, with Marvell (MRVL) plunging 10% on disappointing gross margin guidance despite raising 2027 revenue forecasts. The selloff followed concerns about AI chip revenue timing with Alphabet. Most megacap tech stocks gained, however, with Alphabet and Salesforce advancing.

Retail: Gap surged on strong performance, while Ulta Beauty declined after comparable sales growth slowed in Q2.

Payments: PayPal fell after Bloomberg reported a consortium involving Advent and Stripe abandoned acquisition talks.

Market Implications

With markets split on the Fed's September decision, investors will closely monitor upcoming inflation and employment data. The hawkish Fed stance suggests continued pressure on rate-sensitive sectors, while AI demand remains a key driver for technology valuations.
