NEW YORK, Feb 9 (Reuters) - Global stocks rose on Tuesday and the euro is on track for its biggest one-day gain in 2-1/2 months on expectations euro zone countries will step in to help fix the Greek debt troubles that have soured risk appetite.
The euro's gains against the U.S. dollar gave commodity prices a fillip, boosting spot gold and crude oil prices by one percent.
"Investors are basically looking at speculation of a Greek bailout as an excuse to book some profits on recent gains in the dollar against the euro," said Omer Esiner, senior market analyst at Travelex Global Business Payments in Washington.
U.S. stocks benchmark stock indexes all opened with a better than 1.0 percent gain, erasing losses of the prior session as bailout expectations buoyed sentiment and brokerage comments helped lift industrials such as construction equipment maker Caterpillar.
