Lockheed shares sink further on Trump's F-35 threat

Lockheed shares were down about 0.8 percent in morning trade, nearing their lowest levels since the Nov. 8 election and serving as the biggest drag on a basket of defense-related stocks . Boeing's stock was also down, by about 0.2 percent. "Based on the tremendous cost and cost overruns of the Lockheed Martin F-35, I have asked Boeing to price-out a comparable F-18 Super Hornet!" Trump said.
