Taiwan's specialty chemical stocks are drawing heavy buying, and Everlight Chemical is the standout winner as money chases semiconductor supply-chain plays.

• Everlight Chemical jumped to its daily limit with a huge queue of unfilled buy orders waiting behind it.
• Buyers like its shift from old-school dyes into high-end chemicals, including a photosensitive material used in advanced chip packaging.
• Sales have grown by double digits for three straight months, and the company is expected to swing from last year's loss to a profit this year.
• Taiwan's push to make more chip materials at home is the bigger story driving the whole group.
• The broad market is right at the 50,000 mark after a huge jump, with TSMC at a record and foreign money pouring in, though memory names and panel maker AUO are being dumped.

Outlook: The next test is whether chip and advanced packaging orders keep ramping once the busy season fades, and whether the index can finally break 50,000.
