GoPro is down more than 10%.

The current quarter earnings beat the expectations, but it was the fourth quarter guidance that disappointed the Wall Street.  The company revised the fourth-quarter earnings down by 10% to $470 million in revenue from the original projected earnings of $521.2 million.

GoPro was up as much as 34.21% in September.  After the earning announcement today, it is up only 8.32% year to date.
