The 纳斯达克指数 is currently down 351分（-2.07%） at 16,475.75, after falling to a session low of 16,420.56. The high for the day reached 16,600.36.

From a technical perspective, today’s sharp drop has taken the index 跌破100小时移动均线 (blue line on the chart above), currently at 16,673.30. The price had moved above this level on 4月14 and remained there through yesterday’s session, but today’s gap back below suggests a 重新看跌.

Looking ahead, the next key downside target is the 50-小时均线, which comes in at 16,330.78 and is gradually rising.

Nvidia’s stock opened lower today and 跌破100小时移动均线, currently at 106.11美元. Also in close proximity is the 50-小时移动平均线为106.46美元, reinforcing this area as a 坚固抵抗区. To regain bullish momentum, the price would need to break back above 两个移动平均线 and hold.

Yesterday, Nvidia briefly moved above its 200-小时均线—the 过去一周的第三次尝试—but once again 未能维持突破, highlighting a recurring technical rejection.

Adding to the bearish tone, the high from 四月9 stalled at 115.03美元, which corresponds to the 50%回撤 of the decline from the February high. The inability to break through that level has further dampened bullish sentiment.
