Stitch Fix curates personalized shipments of clothing and accessories for subscribers. The company went public in November and has seen its stock double in value since, despite some big single-day swings.

Last month, Stitch Fix jumped more than 14 percent on speculation that Oprah Winfrey would be taking a stake in the company. Just two weeks prior, the stock posted its biggest single-day gain, surging more than 26 percent on June 8 following a strong earnings beat.

Stitch Fix is up more than 50 percent in the past month and more than 20 percent in 2018.
