* World stocks gain on further economic rebound signs

* Wall St mixed as GM shares weigh on U.S. stock indexes

* Oil at six-month high, emerging-market stocks rally

NEW YORK, May 27 (Reuters) - World stocks rose along with oil prices on Wednesday as signs of economic recovery sprang up from Japan to the United States, curbing investor appetite for lower-yielding assets such as U.S. Treasuries.

Data showing a pick-up in U.S. home sales added to news that Japan's exports rose again in April and consumer confidence improved in France and Sweden, putting a benchmark index of global stocks on track to close at its highest level so far this year.

U.S. crude oil prices CLc1 jumped more than 1 percent to over $63 a barrel, their highest in six months, sending emerging-market stocks rallying.

"There's no question that the extreme collapse in the economy that we saw in the fourth and first quarters is over," said Robert Blake, senior currency strategist with State Street in Boston.

"But things are still not that great out there, so we are a little skeptical of the 'green shoots' optimism on the economic side," he added.
