TOKYO: Japanese shares jumped on Wednesday, with the Nikkei hitting a 1-1/2-month high, as investors bet Prime Minister Yoshihide Suga’s manoeuvring might help restore political stability.

The Nikkei average gained 1.29% to 28,451.02, its highest close since July 14, having broken above key resistance levels such as the 200-day average at 28,281.

The broader Topix rose 1.03% to a five-month closing high of 1,980.79.

Domestic media reported on Tuesday that Suga intended to dissolve the lower house of parliament in mid-September and was considering holding the general election on Oct. 17.

While Suga said he had no such plan, few investors took his comments at face value, given traditional understandings that prime ministers are allowed to lie when it comes to dissolving the parliament.

“There is speculation Suga might install someone popular as his secretary general and call a snap election as soon as next week,” said Norihiro Fujito, chief investment strategist at Mitsubishi UFJ Morgan Stanley Securities.

Polls show Suga remains unpopular but not enough to let opposition parties defeat the ruling coalition, with falling domestic coronavirus cases providing additional boost.

Historically, the market tends to perform well after the parliament is dissolved, making short-sellers nervous about sticking to their positions.
