Investor Michael Burry announced he is increasing short positions on Micron Technology, Nebius Group, the iShares Semiconductor ETF (SOXX), and Palantir, citing expectations of a memory chip downcycle within two years as production catches up with demand. He referenced a Taiwanese media report quoting Acer CEO Jason Chen on rising Chinese memory production capacity, which could lead to oversupply. Burry also increased long positions in QXO, Build-A-Bear, Sprouts, Birkenstock, and MercadoLibre. The Nasdaq-100 hit an all-time high, with Burry describing it as 'historically overvalued and historically top heavy.'
