 Shares of Big Lots Inc. BIG, 2.44 dropped 6.0 in premarket trading Friday, as the discount retailer swung to a narrower-than-expected fiscal third-quarter loss and sales that fell less than forecast, and provided a downbeat earnings outlook for the current quarter as supply chain issues weight on gross margin. The net loss for the quarter to Oct. 30 was 4.3 million, or 14 cents a share, after net income of 29.9 million, or 76 cents a share, in the year-ago period.
