Today's performance of the American stock market was marked by divergence, with the Nasdaq Composite Index (Nasdaq) experiencing a slight decline due to poor performance in technology stocks, closing down by 0.3%. This suggests concerns about highly valued technology companies. The Standard & Poor's 500 Index (S&P 500) showed a more stable performance, falling only by 0.16%, thanks partly to boosts from various industry sectors. On the other hand, the Dow Jones Industrial Average (Dow), which represents traditional economic indicators, ended up by 0.09% as some large blue-chip stocks rose, reflecting optimism towards traditional industries. As a whole, the US stock market has shown a certain level of volatility recently, and investors need to pay attention to future market dynamics and macroeconomic factors.
