According to CoinMeta, U.S. stock index futures rebounded after experiencing sharp fluctuations. Previously, the Democratic Party's victory in mid-term elections and full control of Congress led to a significant sell-off in the U.S. stock spot market on the previous trading day. Daniel Murray, the deputy chief investment officer of an asset management company, stated that the current prudent approach is to be prepared for continued sector rotation and high market volatility. He advised investors to objectively review their portfolio allocations in light of fundamental factors to avoid being swept up in market sentiment and panic. Stephan Kemper, the chief investment officer of BNP Paribas Asset Management Germany, noted that the core question the market needs to answer now is whether tech stocks have indeed become investment-worthy assets or if they represent a value trap. He pointed out that tech stock valuations are currently far below their long-term average, and profit forecasts have not yet seen a significant downward adjustment, which supports the former view. Greg Boland, a market strategist from New Zealand, said that the current rebound seems more like a buying opportunity on dips and a covering of short positions, rather than a fundamental shift in market sentiment. The more important question remains whether the massive investments in artificial intelligence infrastructure can truly translate into the profits and cash flows that investors had previously anticipated.
