GoPro (Nasdaq: GPRO) shares are on watch following mixed commentary in the WSJ over the weekend.

The WSJ noted recent commentary from GoPro finance Chief Jack Lazar, whom said the smaller Hero4 Session is having a tough time competing against the more expensive Hergo4 Black and Silver models. The sales trend could make Q4 a difficult one for the company.

GoPro draws about 40 percent of its annual revenue in Q4.

Lazar did note that GoPro sold about 6.5 million devices on the last 12 months, which is up 64 percent on the year.

Notably, Citigroup analyst Jeremy David sees GoPro's addressable market at about $20 billion, which is over 10 times the company's current run rate.

With GoPro shares falling by about 50 percent over the last month, the stock's forward multiple of 16 times earnings could be a good deal for bargain hunters.

Shares of GoPro are indicated for a higher open Monday.
