GE comes up big, Blue Apron shows promise, polar vortex hits GM

Here are the companies the Yahoo Finance team is watching today.

There’s a lot of excitement over at General Electric. Investors are turning bullish on the stock despite a miss on earnings. Still, revenue beat, driven in part by strong results from its aviation division. GE also is settling a Justice Department investigation into its now-defunct subprime mortgage business.

Things may finally be starting to turn around at Blue Apron. The meal kit service reported a smaller loss than expected, and it just barely beat on revenue. Orders per customer were also up. The CEO says it’s entering 2019 with new confidence in its strategic direction.

The polar vortex is stopping work at more than a dozen General Motors facilities. The company suspended operations at several plants and support buildings in Michigan due to a fire that's leading to a shortage of natural gas. Ford and Fiat Chrysler also are cutting gas use, until the utility there can make repairs.

Blackstone just cut a big deal to buy a controlling interest in Tallgrass Energy. The private equity firm agreed to acquire a majority stake in the energy company for $3.3 billion. That gives Blackstone a 44% stake in Tallgrass. The deal is set to close in the first quarter of this year.

Charles Schwab is giving its own stock a big vote of confidence. The company's board of directors has approved a $4 billion stock buyback. Charles Schwab is also hiking its quarterly dividend by 31% to $0.17 a share.
