Odaily Planet Daily News: Most of the gains in the S&P 500 over the past two years have been driven by the seven largest companies (Apple, Nvidia, Microsoft, Alphabet, Amazon, Meta and Tesla), which have had a bad start in 2025 and have fallen into an adjustment range, wiping out about $1.4 trillion in market value. The Bloomberg "Big Seven" index has fallen about 10% from its high in December last year. Tesla led the decline with a drop of more than 25% this year, followed by Microsoft and Alphabet. Tesla's stock price once soared after Trump won the election, but has since been sold off sharply. Tesla's stock price has been troubled by a series of poor sales reports and increased competition. However, as investors recognize Meta's artificial intelligence strategy, the company's stock price has risen against the trend this year. Meta set its longest winning streak ever in February, rising for 20 consecutive trading days and adding more than $320 billion in market value. (Jinshi)
