Taiwan Glass and other fiberglass cloth makers shot higher, a relief rally for investors who have been sitting on losses.

• Japan's Nittobo, the world leader in fiberglass cloth, opened sharply higher and pulled Taiwan's fiberglass names up with it.
• Taiwan Glass jumped over 6% at the open, back above the NT$60 mark after dipping into the low NT$40s not long ago.
• Trading volume blew past the previous full day's total within the first 15 minutes.
• Foreign investors and dealers were buyers the day before, and July sales at Taiwan Glass hit their best level since late 2021, pointing to a real pickup in business.
• Analysts caution against chasing the rally, since plenty of investors bought higher up and may sell into strength.

Outlook: The group's direction stays tied to Nittobo, with the risk that trapped holders cap the bounce.
