BlackBerry maybe making a comeback.

Shares of BlackBerry rose nearly 15% Thursday after the company posted strong gains in sales of its software and services. BlackBerry stock has done better than Apple and the FANG of four (Facebook, Amazon, Netflix and Google) that rule tech world so far in 2017.

BlackBerry is still probably most well-known for its QWERTY keyboard phones that used to be extremely popular on Wall Street and with many business consumers, governments and celebrities.

It lost market share to Apple following the introduction of the iPhone as well as companies that make phones running on Google owner Alphabet 's Android operating system, such as Samsung. Chen inherited a company in turmoil amid rampant speculation it would not survive.

But BlackBerry has cleaned up its balance sheet under Chen. The company now has $2.5 billion in cash and investments and just $739 million in long-term debt. It no longer makes its own phones but has outsourced its manufacturing as they also have embraced Android.

Software now makes up more than 40% of BlackBerry's sales. Big malware attacks like the WannaCry bug from earlier this year have helped boost BlackBerry's profile.
