Emergency Medical Services Up Sharply (EMS)

Emergency Medical Services Corporation

is up sharply today, gaining more than 14% on more than four times its average volume. There is no news out that would make the stock move as much as it has, or on this heavy volume, so perhaps there is a deal in the works that someone has caught wind of or an activist investor could be taking a stake in the company. It's something to keep an eye on in the coming days and weeks ahead. Emergency Medical Services operates in the ambulance and facility-based physician services market in the United States. It operates in two segments, American Medical Response and EmCare.
