GM thrives in China, Blackberry sues Facebook, Oprah sells Weight Watchers shares, Target expands curbside pickup

Here’s a look at some of the companies the Yahoo Finance team will be watching for you.

General Motors (GM) tops our list. The carmaker says February sales in China grew 7.8% year over year. This brings GM’s 2017 sales volume to over 4 million vehicles, up nearly 4.5% from a year ago.

Blackberry (BB) is taking Facebook (FB) to court. The software company alleges Facebook and its Whatsapp and Instagram apps copied technology and features from Blackberry Messenger. This isn’t the only patent infringement case Blackberry has launched. It’s been in litigation with Nokia (NOK) and Qualcomm (QCOM) for similar claims.

Shares of Weight Watchers (WTW) are shedding a few pounds today. The stock is trading lower after Oprah Winfrey sold around a quarter of her shares in the diet company. Winfrey says the sale has nothing to do with loyalty to the company and that she will continue to serve as a Weight Watcher’s board member, adviser and spokeswoman.

Target (TGT) is expanding its curbside pick-up service. Customers nationwide will now be able to drive to their nearest Target and wait just a couple minutes for an employee to deliver their package directly into their cars. According to Target, beta testing of the feature saw a 10% boost in orders.
