GoPro (NASDAQ: GPRO) shareholders got a break last week, but it may be hard to justify the pop once you dig deeper into the reason for the 7.5% gain. Shares of the leading maker of wearable cameras moved higher after announcing a new round of layoffs that would help hack away at its operating expenses. The former market darling also announced that it would land at the high end of its earlier revenue guidance, triggering a round of upbeat analyst notes.
