Dunkin’ Donuts Shares Jump

America might really run on Dunkin’ now. The parent company of Dunkin’ Donuts and Baskin-Robbins took the stock public Wednesday, causing a 47 percent jump in stock prices on its first day. Wall Street hoped the strong opening for Dunkin’ Donuts would set the tone for the rest of the week, since nine companies plan to go public this week. But investors were wary about Dunkin’ Donuts' strong opening after their rival chain, Krispy Kreme, had a 76 percent jump in stock on its first day as a publicly traded company but soon became a disappointment to investors.
