Odaily News The amazing rise of Nvidia (NVDA.O) stock since the beginning of last year has finally come to an end, at least in the eyes of New Street Research analyst Pierre Ferragu. Ferragu downgraded Nvidia's rating from buy to neutral. He believes that after rising 240% last year and 157% this year, Nvidia's stock price has "fully reflected" the valuation. Nvidia's increase this year ranks second among S&P 500 components, second only to another AI concept stock Super Micro Computer Inc. Nvidia's market value has increased by $1.9 trillion this year, and it once won the title of the world's most valuable company. New Street set Nvidia's target price at $135 in one year. (Jinshi)
