Shares of Advanced Semiconductor Engineering Inc (ASE, 日月光半導體) yesterday took a nosedive on the first trading session after a weekend fire at one of its plants in northern Taiwan, as investors worried the damage would take a toll on the company's bottom line.
The fire fueled a sell-off yesterday, driving down ASE's share-price by the 7 percent daily limit to NT$19.35 on the Taiwan Stock Exchange.
"The impact will last for a longer period of time on the company's financial results. Probably two quarters," said Murat Atamer, a semiconductor analyst with Primasia Securities Co in Taipei.

"Restoring flip-chip packaging and the production of substrates is our top priority," Tung said.
In the meantime, to fill the shortfall, ASE has requested local firms, including Phoenix Precision Technology Corp (
Boosted by the news, shares of Phoenix Precision surged by the 7 percent daily limit to NT$26.05, approaching a one-year high.
