Taiwan's Wistron fell sharply the day after breaking NT$200, a warning to anyone chasing the AI hardware rally, though the wider Taiwan market is booming.

• Wistron dropped hard after hitting NT$200, sliding to around NT$182 as traders cashed out.
• The trigger was its new overseas share sale, priced near NT$186 — buyers lose interest once the stock runs about 7% above that price.
• Wistron says the money will pay for parts bought in foreign currency, and the extra shares dilute existing holders by about 7%.
• The stock has failed at NT$200 three times since June and has been swinging between NT$150 and NT$200 all summer.
• Analyst Lu Han-wei says to wait for August sales figures due around the 10th; a return to triple-digit growth is what would justify holding above NT$200.

Outlook: Taiwan's index just surged past 47,000 on record foreign buying, but Wistron itself likely stays stuck below NT$200 until its August revenue lands.
