HONG KONG, Feb 3 (Reuters) - Asian stocks rose on Tuesday, helped by a tech sector rally and new measures by Japan and Australia to support their economies, but sentiment remained negative amid concerns about plunging company earnings.
The stock market gains undermined government bond prices, while major European stock markets were expected to open as much as 1.8 percent higher, according to financial bookmakers.
Japan and Australia unveiled aggressive new measures to stabilise markets and support their economies, but the moves gave their stock markets only a brief boost as the growing number of companies warning about their results suggested the strength in equities could be fleeting.
Japan's central bank said it would buy $11.2 billion worth of badly performing shares off the books of the country's struggling financial institutions, and Australia's government unveiled a $26.5 billion second stimulus package. [
]"Hopes for steps to improve the demand and supply balance of stocks and economic stimulus measures overseas will lend support to the market, which is deeply undervalued," said Junichi Misawa, senior fund manager at STB Asset Management in Japan.
"But the reality is that we still don't see the bottom for the economy or corporate earnings and that will cap further gains in the market for a while."
Technology stocks, beaten down in recent weeks, led a modest rally in equities, which in turn helped investor willingness to take risks and lifted higher-yielding currencies such as the Australian and New Zealand dollars.
The MSCI index of stocks in Asia-Pacific excluding Japan <.MIAPJ0000PUS> rose 1.2 percent. The healthcare, materials and technology sectors were the biggest percentage gainers among the sectors in the region.

Hopes that the White House will, in addition to pumping more than $800 billion of stimulus into the economy, also create a new fund to house bad bank debt have been redirecting investors' capital back into equity markets.
Last week equity funds around the world saw $1.56 billion in fresh money, bond funds took in $35 million and money market funds received $6.8 billion, according to Boston-based EPFR Global, which tracks $11 trillion in total assets.
Among large emerging markets, investors continued to favour China.
"Since the New Year there has been a clear split in the fortunes of the four BRICs markets, with investors gravitating towards China and Brazil at the expense of Russia and, to a lesser extent, India. China Equity Funds absorbed $43 million for the week, the eighth time in 10 weeks they have recorded inflows," the firm said in a note.
In the currency market, the Australian dollar strengthened against the dollar and yen, after the Australian government announced its stimulus package [
].The euro was steady at $1.2841 <EUR=> while the U.S. dollar was hardly changed against the yen at 89.47 yen <JPY=>.
After rallying overnight on a raft of dour economic reports, U.S. Treasuries came under pressure during Asian hours after the Bank of Japan's latest efforts.
The benchmark 10-year note's yield <US10YT=RR>, which moves in the opposite direction of the price, ticked up to 2.75 percent from 2.72 percent late on Monday in New York.
U.S. crude oil futures recovered to trade 1.4 percent higher at $40.64 a barrel <CLc1>, after falling nearly 4 percent a day earlier due to economic gloom and after U.S. refinery workers averted a strike that would have slashed fuel production.
