HONG KONG, Aug 13 (Reuters) - Asian stocks and commodities rose on Thursday after the Federal Reserve said it spotted stability in the U.S. economy, spurring investors to buy back shares and other riskier assets and sell U.S. dollars.
Major European stock futures were up between 0.1 to 0.3 percent <STXEc1>, the euro <EUR=> rose and German bond futures <FGBLc1> slipped after a surprise rise in Germany's second quarter gross domestic product. [

]Though Asian stocks gained across the board on Thursday, they were largely unchanged so far in August and investors were still uncertain what would support equities beyond bullish sentiment.
"Market sentiment has warmed up but it is not as if investors are gung-ho bullish. They are still a bit jittery," said Junichi Misawa, senior fund manager at STB Asset Management in Tokyo.
"Stocks appear to be overvalued considering the current level of corporate earnings but I believe that sentiment as it is right now is indicative of a long-lasting run-up."

> reversed course to trade up 0.9 percent, after tumbling 4.7 percent on Wednesday on worries the market surge has outrun China's economic recovery.Still the Shanghai composite has chalked up some of the biggest losses in Asia so far this month, down 9.3 percent.
Leon Goldfeld, chief investment officer of HSBC Global Asset Management, believed A-shares in China held medium-term promise.
"A-shares have risen strongly year to date, some profit taking is possible. However, the underlying fundamentals that drive long term returns, remain robust," he said in a note.
Indeed, Asia ex-Japan markets were generally still expected to outperform, despite increasingly expensive valuations, as capital continued to flow into the region amid growing belief that the global economy had turned the corner.
