Citi cut its price target on Nvidia (NVDA) on the back of Broadcom's (AVGO) $10 billion A.I. chip deal announced last week. Jenny Horne says the cut is notable but points to strong fundamentals and a still-bullish A.I. narrative favoring Nvidia long-term. Applovin (APP) leapt higher to all-time highs after the company was among a group of stocks picked to join the S&P 500 (SPX). MarketAxess (MKTX), Caesars Entertainment (CZR), and Enphase Energy (ENPH) are the outgoing names leaving the SPX.
