2017 will go down as a positive, double-digit year for every major index. The same cannot be said for every stock out there. Rather than dig through a bunch of names that you have never heard of, let's talk about some of the better-known stocks that disappointed in 2017.

Chipotle (CMG  ) suffered almost a 20% decline on the year, moving in a completely opposite direction from the markets. With food illnesses still plaguing many stores and the addition of a disappointing queso to the menu, the company decided to look elsewhere for strong leadership. The company is shopping for a CEO that can get them out of this rut and back to gains.

General Electric (GE  ) will close out the year with almost a 50% loss. The company has made many efforts to streamline and revamp its core businesses, but in this rebuilding phase the stock has suffered. The company has cut losing divisions, and is in the process of getting rid of other holdings that have held them back. They are showing a decent effort to invest in the companies they want to grow going forward. For now though, GE is trading right on lows and could very likely close the year there.

Under Armour (UA  ) is the final name we will cover. The stock is lower by over 40% on the year and many are concerned that there is still more downside. The CEO is currently running both Under Armour and his private equity firm, which has caused many larger investors to raise concerns about his abilities to dedicate enough time to the athletic apparel company, especially since it needs help fast. A new CEO could be just what this stock needs to boost prices in 2018.
