Bank of America has reinstated a "buy" rating on Microsoft (MSFT) and set a price target of $500, implying 31% upside from the current stock price of around $383. The bank noted that Microsoft has sustained multi-year growth potential in cloud computing and artificial intelligence, with a current P/E ratio of 23.96 and a PEG ratio of 0.83, presenting an attractive valuation. Despite Microsoft's stock declining nearly 20% year-to-date, Bank of America recommends that investors increase their holdings during the current market volatility driven by geopolitical tensions, with the expectation of realizing potential gains as the market stabilizes.
