Stock futures opened slightly lower Thursday evening after a record-setting session earlier in the day, with strong earnings results and more encouraging economic data helping support the latest leg higher in risk assets.
Contracts on the S&P 500 edged down, after the index closed at an all-time high of more than 4,200 earlier in the session. Dow and Nasdaq futures also retreated.
Shares Amazon (AMZN) jumped in late trading after reporting first-quarter results and current-quarter guidance that exceeded expectations, with online shopping still booming even as more in-person businesses reopen. Shares of Twitter (TWTR), on the other hand, sank after its current-quarter revenue guidance fell short of estimates, disappointing investors who had hoped to see a stronger pick-up in the company’s ad sales to match trends seen at peer social media companies like Snap (SNAP) and Facebook (FB). Overall, companies comprising about two-thirds of the S&P 500 market capitalization have so far reported results, and 84% of these have topped estimates, according to data from Credit Suisse analyst Jonathan Golub.
