Korean Retail Investors Dump Chip Stocks, Pile Into 3x Leveraged SOXL
Korean retail investors sold semiconductor stocks like Micron, Nvidia, and Marvell, totaling over $100M in net sales, while buying $430.95M of the 3x leveraged SOXL ETF in early September. Investors also diversified into other assets like SGOV, IonQ, JEPQ, and Merck. This shift is seen as a strategy to reduce single-stock risk while maintaining sector exposure.
