Nearly $1 trillion in market value across a group of tech companies vanished last week due to a stock market selloff. However, this week, these companies experienced a significant recovery, leading to a broad rally in the stock market. On Friday, Microsoft and Alphabet reported better-than-expected quarterly earnings, which further boosted the gains of these companies. By the end of Friday’s trading session, the group had collectively gained $654 billion in market capitalization, marking the largest weekly increase since November.
