Stocks gained yesterday, taking the index to its highest in a year. Computer-memory chipmakers such as Nanya Technology Corp (南亞科技) and ProMOS Technolo-gies Inc (茂德科技) rose on optimism demand for chips will increase in the second half.

About 6.6 billion shares changed hands, 94 percent above the average daily volume in the past three months. The value of trading was NT$146.3 billion (US$4.2 billion), 113 percent above the average daily value traded in the last three months.
"Investors are betting computer replacement demand will increase this year as the massive purchase of computers around the year 2000 should start to be replaced," said Eddie Chiu, a fund manager at First Global Investment Trust Co (元大投信).
"The latest computer models have much higher demand for memory chips, creating a windfall for companies like ProMOS Technologies and Nanya Technology," he said.
Chiu counts ProMOS Technologies among his investments.
Nanya, the world's fifth-largest maker of computer-memory chips, rose NT$1.8, or 6.7 percent, to NT$28.50. ProMOS rose NT$1, or 6.7 percent, to NT$16.
