The U.S. crude oil and iPath S&P GSCI Crude Oil Total Return (NYSEARCA:OIL) edged up 3.8% to $42.63 a barrel, lifting investor sentiment and driving stock prices. The gain in oil was triggered by factors such as a drop in U.S. crude oil production and hints that OPEC members could reopen talks to curb global oil glut. Some investors are also betting that the Federal Reserve officials meeting next week will be more cautious in interest rates adjustments.

In the U.S., finance and energy stocks led the gains, with all the major stock indices continuing their upward rally.
