Costco e-commerce sales jump, Amazon to sell Chromecast and Apple TV

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

Costco (COST) is living proof that big-box retailers are not down for the count. The wholesale retailer crushed profit estimates last quarter while posting its 14th straight month of sales gains. Costco expanded its online offerings and said membership renewal rates held steady, after a warning last quarter that they could drop.

Shares of CSX (CSX) fell off the rails today. The railroad giant announced its chief executive, Hunter Harrison, is taking a medical leave of absence. Despite having a condition that requires him to use an oxygen tank, Harrison was installed by activist investors to lead the CSX back in March. The company’s COO and Harrison’s confidant, Jim Foote, will serve as acting CEO.

Ford (F) is trying to crack the code on fuel-efficient SUVs. Reuters reports CEO Jim Hackett says the automaker is changing its SUV product strategy after consumers said they wanted SUVs that had the fuel efficiencies of sedans.

You will soon be able to finally buy Google’s (GOOG) Chromecast and the Apple TV (AAPL)  on Amazon (AMZN). It had removed the streaming devices two years ago citing “customer confusion,” but has since had a change of heart. Last week, Google pulled its YouTube from Amazon’s EchoShow and Fire TV claiming a “lack of reciprocity.” No word yet on whether Google will put YouTube back on Amazon devices.
