NEW YORK, Aug 15 (Reuters) - U.S. stocks mostly edged higher on Friday, as a drop in the price of oil added to hopes of a revival in consumer spending, boosting the outlook for economic and profit growth.
The Dow industrials and the S&P 500 held modest gains in early afternoon trading, while the Nasdaq dipped.
A rally in the U.S. dollar on fears about slowdowns in non-U.S. economies pushed the price of oil down more than $3. Oil's decline spurred hopes that consumers will go shopping with the money they save at the pump and that view helped lift retailers' shares.
The tone for retailers was set late on Thursday after Kohl's Corp <KSS.N> raised its full-year forecast, saying tight expense controls would help it weather a tough U.S. economy.
Mid-tier department store operator J.C. Penney Co Inc <JCP.N> added to that optimism, when it reported earnings that beat Wall Street's expectations on Friday morning.
Big manufacturers and airlines, whose earnings take a hit when fuel costs rise, also gained. A report showing a surprising rise in manufacturing activity in New York state in August added to the positive tone.
"Stocks have been directly linked to oil prices for some time and the further decline in oil prices is definite support for the consumer and definite support for the economy," said Alan Gayle, senior investment strategist at Trusco Capital Management in Atlanta.
"So equities are liking the decline in oil and they are liking the stronger dollar. The weakness that was apparent in the U.S. last fall is spreading overseas and causing foreign currencies to move downward, which makes U.S. stocks look better."

In contrast, shares of iPhone and iPod maker Apple Inc <AAPL.O> slid 1.6 percent to $176.51 and ranked as the heaviest weight on the Nasdaq 100 <
