The market movement is quite remarkable. Sectors like new cloud computing, optical fiber, and storage, which were all oversold, rallied from pre-market to intraday levels without any sharp drops, indicating that it wasn't simply short covering; new funds have entered the market. Previous analysis suggested that funds would favor strong large-cap stocks, with their stabilization带动了 (leading to a rebound in oversold stocks). If oversold stocks rallied quickly, it indicated even greater demand from funds, which would increase short-term volatility and shorten the duration of any rebound.
