TOKYO, Dec 9 (Reuters) - The Nikkei average rose 0.5 percent on Tuesday, buoyed by exporters such as Honda Motor Co <7267.T> on optimism for U.S. economic plans and a government bailout of the "Big Three" automakers.
Komatsu <6301.T>, the world's second-largest maker of earth-moving equipment, and other construction machinery shares extended Monday's gains on hopes for U.S. President-elect Barack Obama's infrastructure spending plan.
"Expectations for Obama's administration were reflected positively also in the Japanese market," said Fumiyuki Nakanishi, manager at SMBC Friend Securities.
"But the Nikkei average was pushed back when it neared 8,500 ahead of the settlement of Nikkei futures and options contracts later this week."
The benchmark Nikkei <
> added 40.38 points to end the morning at 8,369.43, after rising as much as 2 percent earlier. It shot up over 5 percent the previous day.The broader Topix <
> gained 0.7 percent to 817.88.The closely watched settlement price, known in Japan as the special quotation or "SQ," is calculated from the opening prices of the 225 shares in the Nikkei average on the second Friday of the month.
Kazuhiro Takahashi, general manager at Daiwa Securities SMBC, said data showing Japan's economy shrank more than initially estimated in the third quarter also helped put a brake on further gains in the market, coupled with uncertainty over Obama's plans. [
]"Still, there's a sense of relief because the Big Three automakers will likely manage to survive. If they were to fail, that would have led to a further deterioration in the economy," he said.
"On the whole, we have optimism for now."
U.S. stocks rallied to their highest level in a month on Monday on optimism that Obama's proposed infrastructure spending could limit the depth of the recession and on hopes for the bailout of the three automakers -- GM <GM.N>, Ford <F.N> and Chrysler <CBS.UL>. [
]Obama has started by asking his economic team to come up with a plan to create at least 2.5 million new jobs by 2011. Congress is also expected to pass a hefty new economic stimulus bill in January that could be ready for Obama's signature immediately after he is sworn in.
Meanwhile, the White House reviewed a Democratic plan on Monday to bail out stricken automakers with up to $15 billion in loans, a move that would also clear the way for longer-term help if industry meets certain conditions. [
