Moderna Upgraded, Baidu Downgraded in Wall Street Analyst Calls

Wall Street analysts have issued several key upgrades and downgrades affecting major stocks. William Blair upgraded Moderna (MRNA) to Outperform from Market Perform following positive interim results for its melanoma vaccine candidate, which could lead to regulatory filings with Merck. Morgan Stanley also raised Honeywell Aerospace (HONA), citing undervaluation post-spinoff. On the other hand, Baidu (BIDU) was downgraded by Morgan Stanley to Underweight from Equal Weight due to weak performance in its core advertising business despite growth in AI cloud infrastructure revenue. JPMorgan cut Klarna’s rating to Neutral and reduced its price target amid uncertainty about medium-term trends. Analysts also initiated coverage on several companies, including Zoom Communications (ZM), which received a Buy rating from BofA due to durable recovery signs.
