According to data from Vanda Research, U.S. retail investors recorded their largest single-day net sell of individual stocks since the March 2020 pandemic crash this Tuesday, amounting to $213 million. Around 88% of the selling pressure was concentrated in the memory chip sector, with Micron (MU), SanDisk (SNDK), Seagate (STX), and Western Digital (WDC) being the main targets of the sell-off.
