New York ? Wall Street finished a tumultuous week on an upbeat note Friday, with stocks posting a solid advance and raising hopes that the worst of the market’s decline might be over.

The gain helped the Dow Jones industrials achieve their biggest weekly advance in 10 weeks.

The week marked the first time since July 1-5 that the Dow, the Nasdaq composite index and the Standard & Poor’s 500 index all had two winning sessions.

The Dow closed up 78.08, or nearly 1 percent, at 8,264.39. The blue chips ended the week up 3.1 percent, their best showing since they rose 4.2 percent the week of May 17.

But the week was mixed for the broad market with the Nasdaq falling 4.3 percent and the S&P 500 rising 0.6 percent.
