A Taiwanese lithium battery maker has been forced into a restricted trading category after heavy losses, and the stock is collapsing — bad news for anyone holding it.

• Sisheng's net worth fell below half its share capital in the second quarter, so the exchange moved it to full-cash settlement starting today.
• The stock has hit its daily loss limit two days running, with more than 2,000 lots still lined up to sell and no buyers.
• Full-cash settlement means buyers must pay upfront and sellers must deliver shares first, which usually kills trading volume.
• The company lost NT$47 million in the first half of the year; steelmaker Chia Kang and Sinnet were hit with the same restriction.
• The timing is brutal — Taiwan's main index dropped over 900 points as Asian tech stocks sold off, with Samsung and SK Hynix both down sharply.

Outlook: Sisheng will keep falling until the sell orders clear, and it can only return to normal trading if it turns a profit again.
