Wall Street ends choppy session mixed, S&P adds more than 1.5% for the week

• Rising crude oil prices boost energy shares on Friday.
• Nonfarm payroll growth beats market expectation by a wide margin.
• Amazon's dismal sales outlook weighs on the consumer discretionary sector.

Major equity indexes in the U.S. started the day mixed and struggled to make a decisive move in either direction as the retail giant Amazon's disappointing sales outlook overshadowed January's labour market report. 

The S&P 500 Consumer Discretionary Index lost 1.77% on the day to become the worst performing major sector. On the other hand, on the back of U.S. sanctions on Venezuela and OPEC's declining output, the barrel of West Texas Intermediate rose above $55 to boost the S&P 500 Energy Index, which added 1.83% to lead the gains. Out of 11 major S&P 500 sectors, 5 of them posted losses on Friday.

Earlier in the day, the U.S. Bureau of Labor Statistics announced that nonfarm payrolls increased by 304,000 in January compared to the market expectation of 165,000. Commenting on the data, "What the unemployment report is telling you is that people want to go back to work. The consumer needs to be strong, and if the consumer is employed, the consumer will stay strong,” Tom Martin, senior portfolio manager at GlobAlt Investments in Atlanta, told Reuters.

• US: Total nonfarm payroll employment increased by 304K in January vs 165K expected.

Other data from the U.S. revealed that the manufacturing sector stayed healthy in January with both the ISM's and Markit's PMI readings coming in above analysts' estimates. Supported by the data, the S&P 500 Industrials Index closed 0.2% higher.

• US: Markit Manufacturing PMI comes in at 54.9 in January vs 54.5 expected.
• US: ISM Manufacturing PMI improves to 56.6 in January vs 54.2 expected.

 The Dow Jones Industrial Average added 0.26% to 25,063.89, the S&P 500 rose 2.43 points to 2,706.53 and the Nasdaq Composite lost 17.87 points, or 0.25%, to 7,263.87. For the week, these three indexes gained 1.32%, 1.58%, and 1.38%, respectively.
