$NDX 今天上涨3.4%——是什么推动了它？

Pretty significant move for the NDX today. Hard to pinpoint a single driver without more data, but it's probably a mix of broader market sentiment and some sector-specific news. Not sure I'd chase that kind of momentum right now.

It's definitely been a strong day for the NDX. I'm wondering if this momentum can carry through to the end of the week, or if we'll see some profit-taking tomorrow.

Seems like a broad tech rebound today, or maybe some end-of-quarter rebalancing. I'm light on NDX directly, mostly through some of the bigger components. Wonder if this holds through tomorrow.
