In a week when Olympians were on cereal boxes and politicians were on soapboxes, this also happened:
When Kylie Jenner tweets, people listen. Shares of Snap fell 6.1 percent, wiping out $1.3 billion in market value Thursday — the day after Jenner said she doesn’t open Snapchat anymore. Wall Street analysts also have noticed lots of users unhappy with Snapchat’s redesign. Apple needs its cobalt fix. It’s in talks to buy long-term supplies directly from miners, according to people familiar with the matter. The metal is a key ingredient for phone batteries — but is also in demand for electric vehicles. Domino’s Pizza says it’s now No. 1 in global pizza retail sales, passing Pizza Hut. In the past few years, Domino’s has touted digital innovation, such as apps to track orders and testing driverless pizza delivery. Sales of existing homes fell in January from a year earlier by the most in more than three years. The National Association of Realtors said many investors who bought homes at low prices during the housing bust are now renting them out rather than selling. People who like Subway sandwiches might be feeling a little less loyal these days. The company is shaking up its loyalty rewards program, giving customers the ability to earn $2 discounts instead of free Footlongs. Sales at Subway’s U.S. stores fell more than 4 percent in 2017. A judge gave the green light Thursday to a Minnesota company that wants to put advertising in vehicles driven for companies such as Uber and Lyft in New York City. Vugo Inc. sued the city in 2015 after the Taxi and Limousine Commission prohibited the ads in vehicles that were not medallion taxis or street hail liveries.
