Taiwan share prices jumped 3.91 percent to a ten-day high yesterday as investors expected a rally driven by low-interest liquidity next week, dealers said.
The weighted index rose 172.88 points at 4,589.04 on turnover of NT$50.46 billion (US$1.53 billion).
Gainers outnumbered losers 1,461 to 146, while 176 stocks remained unchanged.
A total of 81 shares rose to their daily 7.0 percent ceiling, against 18 limit-down.
The market is at its highest since hitting ending at 4,694.52 on Dec. 19.
"Investors hope to build up their portfolio in advance as they forecast a continued rebound in January fuelled by ample liquidity" after the central bank cut interest rates to aid the ailing economy, said Allen Lin of Concord Securities.
"January is also expected to be short of bad news ahead of the scheduled release of corporate results," he said.
Financial markets will close on Jan. 1 and reopen Jan. 5, so uncertainties during the holidays could affect the trend of the global stock market, which would impact the domestic stock index, analysts said.
