• Best Buy fell 1 percent. The country’s largest consumer electronics retailer reported a 90 percent drop in net income during the second quarter, dragged down by restructuring charges and weak sales. The chain is waging a public fight with its co-founder Richard Schulze, who wants to take the company private. Best Buy’s stock dropped 25 cents to $17.91 and has lost 12 percent this week.

• Barnes & Noble posted a smaller quarterly loss, helped by sales and e-books and surging sales of the “Fifty Shades of Grey” book. The largest traditional bookstore chain still fell 46 cents to $11.88.
