July 30 (Reuters) - Microsoft added nearly $450 billion in market value on Thursday, the largest one-day gain on record for a company, ‌after it forecast stronger-than-expected cloud growth and signaled continued cash ‌generation through its new fiscal year. The software giant's shares closed up more than 15%, lifting ​its market capitalization to $3.35 trillion, surpassing chip giant Nvidia's previous record one-day gain of $441 billion on April 9, 2025, according to LSEG data. Microsoft has lagged some of ​its "Magnificent Seven" peers this year, ‌with its stock down more than 18% up to Wednesday's close. At least nine brokerages raised the target price on the stock, with the mean target now $560.90. Microsoft said its spending plans remain unchanged and that it expects capital expenditures of $50 billion for the fiscal first quarter of 2027 and $175 ‌billion for the 2026 calendar year.
