Myson Century (5314.TW) briefly reached its 11th consecutive limit-up on Aug. 28 at NT$41.8 before falling to the limit-down price of NT$34.2, a 20% intraday swing. Trading volume reached about 20,000 lots, with 2,098 sell orders queued at mid-session. The rally has been fueled by the company’s pivot toward healthcare, wellness products and AI unmanned vehicle systems, as well as a short squeeze (rapid buying by traders closing bearish positions). As of Aug. 26, margin short positions stood at 4,806 lots and securities lending sales at 12,855 lots; after accounting for stock-dividend obligations, estimated buyback pressure exceeded 55,000 lots. Potential impairment for securities-lending short sellers was estimated at up to NT$1.29 billion, based on the NT$14.75 ex-rights reference price and Aug. 27 close of NT$38. Taiwan Stock Exchange trading restrictions apply because the shares were designated a disposition stock. Whether the reversal ends the squeeze or reflects short-term profit-taking remains uncertain.
