BANGKOK (AP) -- Asian stock markets mostly inched higher Tuesday after a round of corporate deals on Wall Street lifted sentiment following last week's gyrations.
Oil prices hovered near $87 a barrel in Asia amid investor optimism that global economy may not be slowing as much as feared. The dollar was higher against the yen and the euro.
Technology shares got a boost on news that Google is buying wireless phone maker Motorola Mobility for $12.5 billion in cash -- the largest deal ever for Google. Japanese memory chip maker Elpida Memory Inc. rose 4.3 percent. Samsung Electronics gained 4 percent and Hynix Semiconductor was up 3.5 percent.
The Google announcement, along with several other acquisitions announced in the U.S. on Monday, helped restore confidence in risky assets because such deals are interpreted as a sign that companies are more confident about the future.
But analysts were cautious about reading too much into Tuesday's stock gains.
"It's still too early to say whether this is a reversal of the previous downward trend. There are still a lot of uncertainties that are keeping investors on the sidelines," said Kwong Man Bun, chief operating officer at KGI Securities in Hong Kong.
