Wednesday was a killer on Wall Street, but there were a few winners. GoPro spiked after getting analyst backing, making it TheStreet's Move of the Day. FBN Securities called a bottom to GoPro with shares now more than half their all-time high set in October, calling the action camera maker a 'category killer.' The company has been beaten down over the past three months after Chinese electronics manufacturer Xiaomi released its far-cheaper Yi camera, a model in direct competition with GoPro's products. Analysts argue the fear over the competition is overdone given GoPro's superior image quality.
