Asian markets ended mostly higher, with major indexes extending their week-long rallies, while trading in Singapore's securities market was halted due to a system glitch.

Singapore's Straits Times Index (Singapore Exchange: .STI) was down 0.13 percent in mid-morning trade, before trading was halted.

The Singapore Exchange (SGX) said in a statement the securities market was "put in adjust phase at 1138 hours due to duplicate trade confirmation messages being generated." The stock exchange operator said duplicate trades were not executed and the market remained "orderly."

The SGX had said trading would resume at 2 p.m. HK/SIN, then pushed that back to 4 p.m. HK/SIN, before saying the market will not re-open on Thursday.

Elsewhere, in Australia, the benchmark ASX 200 (ASX: .AXJO) closed up 23.06 points, or 0.43 percent, at 5,411.60, tacking on a 3.46 percent gain for the week.

Japan's Nikkei 225 (Nihon Keizai Shinbun: .N225) was the standout performer, adding a gain of 8.46 percent for the week, after closing up 154.46 points, or 0.95 percent, at 16,385.89. The Topix (Exchange: .SPTPXN) closed up 10.90 points, or 0.84 percent, at 1,311.16.

Across the Korean Strait, the Kospi (Korea Stock Exchange: .KS11) closed up 3.22 points, or 0.16 percent, at 2,008.77, retracing losses of some 0.2 percent. The South Korean benchmark index is up 2.32 percent for the week.

In Hong Kong, the Hang Seng index (Hong Kong Stock Exchange: .HSI) closed up 238.69 points, or 1.12 percent, at 21,561.06. Chinese mainland markets closed mixed, with the Shanghai (Shanghai Stock Exchange: .SSEC) composite down 6.77 points, or 0.22 percent, at 3,053.91, while the Shenzhen (Dow Jones Global Indexes: .DJSZ) composite finished up 3.2 points, or 0.16 percent, at 2,044.93.

Overnight, U.S. stocks closed near flat but still managed to make it further into record territory .

Markets have rebounded in recent sessions on the expectation of further stimulus measures in Japan and in the UK. But analysts cautioned that if the expectations are not met by policy actions on the part of governments and central banks, market sentiment may be affected.

"In recent days risk sentiment has been buoyed by the expectation of further stimulus and the lack of new news overnight appears to have taken the wind out the market's sails," Rodrigo Catril, a currency strategist at the National Australia Bank, said in a morning note. He added that unless stimulus expectations were backed up with actions, the risk of disappointment would start to rise.
