U.S. stocks ended on a high note Friday, enjoying a week of gains triggered by a 14 percent drop in the price of crude oil. The Dow Jones industrial average rose 0.7 percent for the week, closing at 10,592.21. The tech-heavy Nasdaq, boosted by Intel’s revised sales forecast, closed 2.2 percent higher at 2,147.96. Still, concerns about a new record low for the dollar against the euro—coupled with weak November employment figures, released on Friday— cast a shadow over trading, and stocks, which had rallied to earlier highs, gave back some of those gains by the end of the day. On the Big Board, Omnicom closed down 0.8 percent at $81.59, while IPG rose 0.9 percent to $12.54. WPP, trading as American Depository receipts on the Nasdaq, closed 1.1 percent higher at $55.73.
