NEW YORK — President-elect Donald Trump issued a single tweet blasting defense contractor Lockheed Martin Corp. at 8:30 a.m. on Monday. By lunchtime, he had wiped $4 billion off the company’s market value.

Wall Street traders began dumping the company’s stock after Trump blasted its fighter jet program: “The F-35 program and cost is out of control,“ he tweeted. "Billions of dollars can and will be saved on military (and other) purchases after January 20th.”

With his 17 million Twitter followers and upcoming inauguration to the most powerful job in the world, Trump presents challenges and opportunities that Wall Street has never seen before. Traders not only have to monitor the president-elect’s every word; they also have to follow his Twitter feed. Some are already crafting strategies to cash in on the president-elect’s penchant for bashing individual companies.
