Michael Burry Picks Chip Suppliers Over Micron — But Warns Memory Producers Could Sell Off 'Intensely'

Michael Burry, known for his 'Big Short' bet, has increased his short position in Micron Technology (MU) and other semiconductor-related investments, citing concerns about memory producers' high valuations. He also shorted Applied Materials (AMAT) and Lam Research (LRCX). Micron's stock rose 5% to $1,096.16 on Tuesday, with a 14% gain in September. Burry's views are based on market trends and comments from industry leaders, but he acknowledges the difficulty in timing market tops.
