Humana soars Walmart talks, Trump slams Amazon (again), Alibaba expands

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

Humana (HUM) tops our list. The stock is soaring as investors digest last week’s news that Walmart (WMT) is interested in buying the health insurer. According to Bloomberg, analysts say they don’t necessarily believe a full merger will go through. Instead, they think a partnership that pushes more health care into Walmart’s stores is more likely.

Amazon (AMZN) continues to get the beat down from President Trump. Over the weekend, the president tweeted that Amazon was gutting the Post Office of billions of dollars in package delivery costs. He also went after the Washington Post, owned by Amazon CEO Jeff Bezos, saying the newspaper is a lobbyist group and should be regulated as such.

Alibaba (BABA) wants all-in on food delivery. The e-commerce giant is buying full control of the startup Ele.me as it steps up efforts to expand in China’s fast-growing market for local food delivery of food and other services. Ele.me is said to control 50% of the market. The deal is expected to help Alibaba take on Tencent’s competing food delivery app Meituan Dianping.

Digital Trends reports Apple (AAPL) posted 161 Siri-related jobs in an effort to take on Amazon’s Alexa. The news comes on the heels of Amazon hiring more than 1,100 people to work on Alexa. Critics say that while Apple’s HomePod had better sound than the Echo, Siri struggled to complete even simple commands like turning off lights.
