Fit in the public eye

The jury may still be out on fitness trackers — whether they serve an actual diagnostic purpose or just look cool enough for people to pretend they care about their health — but the business is going great guns. Which is why tracker-maker Fitbit went public and is now valued at over $8 billion. The IPO was priced at $20 a share and the stock hit a high of $44 soon after listing. It currently trades at $42. Given that Fitbit reported revenue of $745 million in 2014, it certainly pays to be fit.
