Closing Bell: United Falls on CEO Health; Stocks Climb for Week

Stocks managed to secure their third straight week of gains on Friday to remain on track for their best monthly performance since October, 2011. Since the beginning of October, the S&P 500 has gained nearly 6%. United Continental (UAL) tumbled on news CEO Oscar Munoz had been hospitalized following a heart attack on Thursday. The airline said it plans to continue to operate normally. Munoz has acted as United's chief since only last month. Crude oil spiked after the number of active oil rigs in the U.S. dropped by 10 over the past week. Commodity traders have been eager to see signs a supply-demand imbalance is being corrected. Mattel (MAT) climbed even following another quarter in which Barbie sales fell.
