Carvana Co, another stock with high short interest, jumped 20% after the used-car retailer said it expects a smaller core loss in the current quarter. Short sellers betting against GameStop have lost $610 million since the start of the week, analytics firm Ortex estimated, adding that about 24% of GameStop's publicly available shares were in short position. Wedbush raised its price target on GameStop's shares to $6.50 from $5.30 after the results, as the brokerage believes the lower cost structure reduces the risk of ongoing losses.
