U.S. stock index futures slipped on Monday after the S&P 500 logged its biggest one-day jump in more than a month in the prior session, with investors shifting their focus to retail earnings this week for clues on the strength of consumer spending. Shares of Discovery Inc jumped 12.5% in premarket trading after news reports said U.S. telecoms giant AT&T Inc is nearing a deal to combine its media assets, including CNN and HBO, with the company.
