NEW YORK, April 24 U.S. stock index futures rose modestly on Wednesday, indicating the S&P 500 may rise for a fourth straight day, as investors braced for the release of a slew of corporate earnings reports and durable goods data.
* Procter and Gamble Co slipped 1.9 percent to $81 in premarket trading after the world's largest household products maker posted third-quarter earnings.
* Eli Lilly and Co rose 1.2 percent to $59 in light premarket trading after the drugmaker reported higher-than-expected first-quarter earnings, helped by favorable taxes and higher sales of treatments for diabetes, depression and lung cancer.
* Ford Motors Co advanced 2.3 percent to $13.67 in premarket trading after the automaker reported its first-quarter earnings.
