Shares in RealReal Inc. REAL, -4.92%, an e-commerce company that sells secondhand luxury goods, jumped more than 13% after its first earnings report as a public company Tuesday. The RealReal went public in late June, receiving an initial valuation north of $1.5 billion that grew quickly on the public markets. Shares took a hit last week, however, after tough earnings reports from two other young e-commerce stocks focused on luxury goods, FarFetch Ltd. FTCH, +5.26% and Revolve Group Inc. RVLV, -2.57% Shares moved higher and lower in after-hours trading Tuesday as investors digested losses that appeared to be much greater than expected until taking the share count into play. RealReal reported second-quarter losses of $26.9 million, or $2.83 a share, on sales of $71 million, up 51% from the year before. After adjusting for stock-based compensation and other effects, the company claimed losses of $2.50 a share, but said that would have fallen to 28 cents a share using the share count expected after the IPO, which took place after the quarter closed. Analysts on average expected adjusted losses of 33 cents a share on sales of $71 million, according to FactSet. RealReal shares closed Tuesday with a 4.9% decline at $17, but were closer to the IPO price of $20 a share in after-hours trading.
