Japan's Nikkei average sprang back on Tuesday from four straight sessions of losses as investors snapped up big name bargains ahead of emergency talks between the G7 industrialised nations to tackle a deepening euro zone crisis.
The Nikkei advanced 1% to 8,382.00, boosted by Canon Inc's gain of 3.4% on plans to buy back up to $640 million worth of its own shares. The camera and printer maker was the top-weighted gainer and the most heavily traded stock on the main board by turnover.
"The market has calmed down from yesterday, but the atmosphere is still very much one of 'wait and see'," said Yasutaka Kuga, a partner at Senrigan Capital. "No one really wants to play their hands."
Leaders of the G7 industrialised nations were due to hold an emergency telephone conference later on Tuesday to discuss a deepening euro zone crisis as Spanish banks show increasing signs of strain and a June 17 Greek election poses the risk that the country may leave the euro zone.
"If nothing concrete comes out of the meeting then people will be disappointed," said Masayuki Otani, chief market analyst at Securities Japan. "But if they give a direction for how they're going to tackle the problems then the market might calm down."
Olympus Corp, which is struggling to recover from an accounting scandal, climbed 4% after the Sankei newspaper reported that it was considering raising about 50 billion yen through a third-party share allotment.
Although unease about the euro zone's fate remained, investors took the opportunity to pick up cheap stocks that were heavily knocked down on Monday on concern about a slowing US economic recovery following a slew of soft economic data over the weekend and a sturdier yen.
