GoPro is best known for its adrenaline-fueled video, but the camera maker has offered shareholders an electrifying ride as well.
While the stock is still up over 100 percent since its IPO in June, it's also down nearly 50 percent from its all-time high of $98 in October.
Among the causes of concern for investors: increasing competition and, more immediately, an impending lock-up expiration.
Thursday, analysts expect GoPro to reports earnings per share of 70 cents on revenue of $580 million, which would represent 61 percent growth on the top line.
What explains that expected surge in sales?
Analysts think that the GoPro camera was a popular holiday gift. Michael Pachter of Wedbush Securities estimates that GoPro shipped at least 2.3 million cameras in the fourth quarter versus 1.4 million in the year-earlier period.
Looking ahead, analysts say the question for GoPro is how effectively the company can now extend its reach into new geographies and products.
For example, GoPro currently dominates 94 percent of the action camera market in the United States, according to NPD. Now analysts argue that the company needs to expand its footprint, especially in China.
