Stocks were narrowly mixed on Thursday as the Nasdaq pulled back from Wednesday's modest gains ahead of the kickoff of earnings season. Domino’s Pizza (DPZ) was weighing on markets after quarterly sales and profit fell short of estimates because of the impact of a stronger U.S. dollar. The pizza chain has been behind an international push, opening nearly 200 locations, mostly overseas, over the quarter. Lumber Liquidators (LL) climbed on news it will pay $10 million to settle five alleged violations it knowingly sourced illegal wood products. Deutsche Bank (DB) was on watch after the bank said it would take a charge of nearly 6 billion euros in the third quarter, tied to higher regulatory requirements in its corporate banking unit.
