July 30 Taiwan trading showed foreign investors buying battered Winbond on the main board while selling TPEx semiconductor and other names, as margin buying by retail investors rose in several beaten-down stocks.
Winbond extended its three-session slide to 25.94% on July 30, falling 8.85% to NT$118.5 even as foreign investors reversed from heavy selling to buy 36,320 lots worth about NT$4.54 billion, making it the second-most net-bought stock on the Taiwan Stock Exchange that day. The move contrasted with broader foreign net selling in Taiwan, including net sales of NT$48.31 billion overall on July 30 and continued selling across a range of TPEx-listed semiconductor, copper clad laminate and industrial PC stocks, where margin buying by domestic investors increased. On the TPEx, foreign investors sold names including Wafers Works, Co-Tech, Vanguard International Semiconductor, GlobalWafers and Taiwan Union Technology, while margin balances rose in several of those stocks, highlighting a split between institutional risk reduction and dip buying by retail or domestic capital. Analysts said that divergence can signal a fragmented shareholder structure and may create future selling pressure if prices fail to stabilize.
