Michael Burry, renowned for predicting the 2008 housing collapse, has issued fresh warnings of a potential downturn in the tech sector as major U.S. stock indexes face significant losses. The Nasdaq and S&P 500 recently fell, erasing over $740 billion in market value. Burry's concerns focus on artificial intelligence and semiconductor stocks, with reports indicating he has purchased put options on a semiconductor ETF, anticipating a possible 30% decline. He likened Nvidia's current market position to Cisco Systems during the dot-com bubble. Simultaneously, Bitcoin's recent surge above $80,000 has sparked debate. Trading firm Wintermute suggests the rally, which saw Bitcoin reach $83,000, was driven more by leveraged short liquidations than by spot demand. Despite Bitcoin reclaiming its 200-day moving average, Wintermute cautions that such leverage-driven rallies can quickly reverse if momentum falters.
