GoPro (GPRO) - Get Report stock was upgraded to a "buy" rating from a "sell" rating at Citi on Thursday. The firm set a $9 price target on the wearable action camera maker.

The upgrade comes as the firm believes recent stabilization in revenue and other restructuring will make the company profitable again.

GoPro gained by more than 15% today after the company said it is expecting first quarter revenue at the high end of its previous guidance.
