The S&P 500 slipped 0.2%, despite a majority of its constituent stocks trading higher. Artificial intelligence-related stocks have remained the key driver of recent market volatility. Micron Technology declined 1.6% after rallying 14.4% over the previous two trading sessions, a move that had almost fully recovered its 13.3% decline from the prior week.
