U.S. stocks lost over $1 trillion this week, declining for five consecutive weeks to hit a new low. The "Seven Giants" collectively lost approximately $870 billion. This week, U.S. stocks experienced a broad decline, with the S&P 500, Nasdaq, and Dow Jones all posting their longest five-week losing streak since 2022, and technology stocks' market value shrank by $870 billion. Meta plunged about 12% due to dual hits from litigation and layoffs. More than half of the overall market stocks have entered a technical bear market. According to BlockBeats, on March 28, the three major indices—the S&P 500, Nasdaq, and Dow Jones—all declined this week, marking the longest consecutive five-week decline since 2022. The combined market cap of the seven tech giants shrank by about $870 billion in a single week, with Nasdaq down more than 13% from its October 2022 high. Under multiple negative factors, U.S. stocks weakened sharply this week. By Friday's close, the Dow Jones dropped 793 points in a single day, the S&P 500 fell to a seven-month low, and Nasdaq further entered a technical correction zone. The average maximum drawdown of the 500 components of the S&P 500 has reached 17%, while Nasdaq components have an even higher average maximum drawdown of 31%, indicating the actual damage is far more severe than the index figures suggest. The technology sector bore the brunt. Meta dropped about 12% over the week, driven by dual setbacks from two defeats in child safety lawsuits and layoffs; Tesla and Amazon also declined more than 3%; Nvidia fell nearly 5% due to a contraction in AI capital expenditure expectations. The "Seven Giants" lost a total of about $870 billion in market value over the week, equivalent to more than 63 trillion RMB. From a market structure perspective, the breadth and depth of this decline should not be underestimated. Although the main indices fell between 7% and 13%, more than half of individual stocks have fallen over 20% from their highs, entering a technical bear market zone. This week, U.S. stocks weakened significantly under multiple negative shocks.
