  • Zendesk investors might need to say “om” a few times today. The customer-service platform’s shares were down 9% ahead of the bell after quarterly results came up short against Wall Street expectations.
  • Shares of Chevron climbed 1.3% premarket after the oil giant swung to a second-quarter profit and reported revenue that beat expectations. The company plans to resume stock repurchases in the third quarter, at an annual rate of $2 billion to $3 billion a year. Rival Exxon Mobil also was up, by 0.7%, after its own earnings report.
  • Trading app Robinhood ‘s shares were down 0.6% premarket, after having notched their first trading day down more than 8%.
  • Caterpillar shares slipped 2.7% premarket. The construction equipment maker reported a quarterly net profit that tripled, though its largest construction business came up short.
  • Procter & Gamble shares nudged up 1.3%. The maker of Pampers diapers and Tide detergent posted sales gains in almost every business unit in the most recent quarter, though growth slowed and profit margins tightened as the company spent more to make and deliver its products.
  • T-Mobile US edged down 0.8% premarket after the telecom company’s revenue and earnings climbed in the second quarter, though it failed to match AT&T ‘s steeper customer gains.
  • Gilead Sciences swung to a profit in the second quarter as revenue increased 21% driven by higher demand. But the biopharmaceutical company was down 1.7% premarket nonetheless, perhaps swept up in the morning’s bearish mood.
  • U.S. Steel shares added 1% premarket. The steelmaker’s sales more than doubled from the year earlier, helped by continued strong demand and low steel industry inventories that are driving up prices.
  • China’s tech crackdown carries risks, because when a government believes it can snap its fingers and create—or destroy—whole industries at will, things can easily go awry, writes Heard on the Street’s Nathaniel Taplin.
