The 纳斯达克 index is surging today, currently trading up 430点（+2.48%），报17，732.80, with an intraday high of 17,739.04. The index has rebounded sharply after forming a 双层底 earlier in the week, with Tuesday’s low at 17,238.24 and a similar low at 17,239.44 in yesterday’s session. This technical pattern gave buyers confidence to step back in.

Overnight, the resolution of the 美国预算协议 that averted a government shutdown further fueled bullish momentum, allowing buyers to push higher. Even at today’s low, the index was still up 188.06分, indicating strong upward pressure. However, the 50小时移动平均线下跌至17，773.68 is now in play, which could act as initial resistance. The NASDAQ has not traded above this key technical level since 2月20, making it a critical test for the current rally.

Despite today’s strong gains, the index remains down 本周-2.58% and is still 较2月18日当周高点下跌-11.9%. Earlier this week, losses exceeded 14% at session lows, underscoring the recent weakness. If buyers can push through the 50-hour moving average, it could signal a stronger recovery, but failure to break above may lead to renewed selling pressure.
