* Yen direction is unclear after 15-year high hit overnight

HONG KONG, Sept 9 (Reuters) - Asian stocks edged up and the yen slipped from a 15-year high on Thursday, after a small rally on Wall Street driven by successful European bond auctions gave investors an excuse to lighten up on their bets.
However, the two biggest issues on investors' minds -- European financial stability and the slowing U.S. recovery -- held bargain hunting in check and risk taking at a minimum.
Australia was the exception, where rising equities led Asia on a solid labour market report, which also drove the Australian dollar to a four-month high. [
]Meanwhile, the yen's 11 percent rise has battered depressed Japanese equity valuations, with stocks trading at the cheapest relative to expected earnings since December 2008.
With uncertainty rife about how much more the yen's climb has to run, investors were cautious about rebuilding their Japanese stock portfolios just yet.
"Worries about Europe were soothed somewhat following a bond auction in Portugal, and that prompted short-covering in the market, which was hit hard by the advance in the yen versus the dollar and the euro yesterday," said Tsuyoshi Segawa, an equity strategist at Mizuho Securities. [
]"But market players were reminded that Europe's sovereign concerns are continuing and that's not something that will improve right away," Segawa said.
