[Citigroup Upgrades U.S. Stock Market Rating, Prefers 'Defensive Stocks'] Deep Tide TechFlow reports that on April 14, like other analysts on Wall Street, Citigroup strategists have become more optimistic about the U.S. stock market. They stated that the heightened uncertainty of the war situation has made investors more inclined to choose higher-quality, more defensive companies. Citigroup strategists have upgraded the U.S. stock market rating from 'Neutral' to 'Overweight' and adjusted global asset allocation based on a 'quality/defensive tilt' principle. They also downgraded the rating of emerging market stocks from 'Overweight' to 'Neutral,' citing these markets' vulnerability to energy shocks and the strengthening of the U.S. dollar. (Jin10)
