Aug 11 (Reuters) - Wall Street was set to open higher on Thursday as strong labor market data and upbeat corporate earnings reports buoyed investor sentiment about U.S. economic growth.
The number of Americans applying for unemployment benefits slipped by 3,000 last week to 266,000 from the week earlier, continuing a trend of being below the 300,000 mark for the 75th consecutive week.
The data follows a set of robust labor market reports including last week's monthly payrolls numbers.
Kohl's kicked off the two-day earnings run of department store chains. The company's shares rose 9.5 percent to $41.65 premarket after its quarterly profit beat estimates.
Macy's shares soared 11 percent after the department store operator reported a smaller-than-expected drop in quarterly comparable store sales and said it would close 100 stores.
Nordstrom rose 5.6 percent in the run-up to the results after market closes, while J.C. Penney, which reports on Friday, was up 5 percent.
Alibaba rose 4.8 percent after the Chinese e-commerce giant posted a 59 percent jump in quarterly revenue. Yahoo, which owns a stake in Alibaba, rose 3.4 percent.

Better-than-expected second-quarter earnings and a set of strong economic data have pushed the S&P 500 to a series of record intraday highs since July.
