Jan 16 (Reuters) - The S&P 500 edged higher in choppy trading ahead of the long weekend on Friday, helped by gains in chip stocks as Wall Street looked to round up a whipsaw week that ushered in the start of the fourth-quarter earnings season.
Memory chipmakers Micron (MU.O), and Seagate Technology (STX.O), gained 5.6% and 2.2%, building on their searing rallies in 2025 on enthusiasm over AI demand.
The U.S. stock indexes gradually moved lower while Treasury yields ticked up after President Donald Trump said he may want to keep economic adviser Kevin Hassett in his current role, lowering market bets that Hassett would succeed Fed Chair Jerome Powell.
Odds of former Fed governor Kevin Warsh becoming the next Fed chair rose to 57%, from 44% on Polymarket, replacing Hassett - a prominent voice pushing for lower rates as the leading contender for the Fed's top job.
Investors this week have also had to contend with worries over the Federal Reserve independence after Powell said U.S. prosecutors had threatened to indict him. Hassett, however, played down the probe saying he expected there would be "nothing to see here".
"The administration seems to be backing off some of that (Fed rhetoric)," said John Belton, portfolio manager at Gabelli Funds, adding that "any attempts to undermine Jerome Powell may seem to be backfiring."

DEFENSIVE SECTORS LEAD WEEKLY GAINS
Consumer staples (.SPLRCS), real estate (.SPLRCR), and utilities (.SPLRCU), - largely considered defensive sectors - were on top of the leaderboard for weekly gains.
