Wall Street analysts have upgraded several stocks including Booking Holdings (BKNG) and Carvana (CVNA), citing market overreactions and buying opportunities. Wedbush raised Carvana to Outperform with a target of $400, believing recent declines are overdone. BofA Securities upgraded Booking Holdings to Buy with a target of $6,000, dismissing fears that Google's AI efforts pose a significant threat to Booking's market position, and viewing the decline as an opportunity. HSBC also upgraded Flutter Entertainment to Buy, while Wolfe Research increased Morgan Stanley's rating to Outperform. Wells Fargo raised Merck to Overweight, citing pipeline progress and new launches. Conversely, some stocks received downgrades. UBS downgraded FROG (Jfrog) and Jazz Pharmaceuticals, citing valuation concerns after recent gains. Jefferies and Evercore also downgraded Exact Sciences and QuantumScape respectively, citing acquisition premiums and valuation levels. Additionally, several companies received initiation and coverage upgrades, including Meta Platforms, Synopsys, Cadence Design, and Hyatt, reflecting positive outlooks on AI monetization, technological backbone, and market positioning. In broader market news, Wall Street experienced volatility with significant gains and losses driven by earnings reports, economic data, and Federal Reserve policy expectations. Notably, Nvidia's earnings and AI chip sales boosted markets temporarily, though concerns over an AI bubble persist. Overall, analysts see the recent market corrections as buying opportunities, with some emphasizing that fears over AI's impact on companies like Booking are exaggerated, and that industry fundamentals remain strong.
