The stock market is facing significant declines, with major indices such as the Dow, S&P 500, and Nasdaq all sliding amid concerns over high valuations, particularly in the tech sector. Nasdaq futures are lower following a rough session, while cryptocurrency experiences losses as Bitcoin dips below $100K. The fall is exacerbated by warnings from CEOs of leading banks like Goldman Sachs and Morgan Stanley, who predict a potential market correction of 10-20%. Investors are on edge as concerns grow over the sustainability of the recent rally in technology stocks following disappointing performance from companies like Palantir. The market turmoil highlights the hesitation among investors as they grapple with the implications of lofty tech valuations and rising fears of a market pullback.
