Lower over 15% in midday trading is the stock of sporting goods retailer Big 5 Sporting Goods Corp (BGFV) - Get Report . The retailer reported a top and bottom line miss for its second quarter, and offered weak third quarter guidance.

Big 5 posted earnings of 13 cents per share, missing projections for 19 cents per share. Revenue came in at $243.7 million missing estimates for $251.41 million.

Shares of Pioneer Natural Resources (PXD) - Get Report , an oil and gas exploration and production company, were falling over 11% during midday trading after it said it would cut its 2017 capital budget by $100 million to save money at a time of weak oil prices. 

The Irving, TX.-based company said when reporting second quarter results that it lowered its full-year production growth guidance to 15%-16% from 15%-18% over drilling delays. It also lowered its oil growth guidance to 17-18% from 24%-28%.

Shares of Nordstrom, Inc.
