But the news immediately spooked investors. Futures tied to the Dow Jones industrial average “indicated an opening loss of more than 400 points, recovering a bit after earlier trading down more than 500 points.

Morgan Asset Management, told Bloomberg’s Yakob Peterseil. But, she said, “with such a wide range of outcomes and implications stemming from the President’s diagnosis, it’s too soon to ascertain what the final market direction will be.”
