Taiwan stocks surged 5.6 percent at Monday's close as political tensions eased after a peaceful rally and moves toward a recount of a disputed presidential election over the weekend sparked across-the-board buying.
The main TAIEX ended up 5.57 percent at 6,474.11 on gains in heavily weighted financial and tech issues like UMC, marking its largest daily percentage gain since October 2002 and recouping more than half of the 10 percent lost last week following the election.
Turnover rose to T$112.43 billion from T$97.79 billion on Friday. The index had been Asia's best performer outside of China this year before the election.
