Ackman's Pershing Square is Penney's largest shareholder.
Vertex Pharmaceuticals - The drugmaker's stock is under pressure after it corrected data involving a trial of its cystic fibrosis treatment. The correction lowers the number of patients showing improved lung function.
Chesapeake Energy - Investor Carl Icahn has taken a 7.6 percent stake in the energy producer. Icahn is calling for at least four of the company’s board members to be replaced. Chesapeake says it agrees with Icahn that its stock is substantially undervalued and that it will “carefully review” his letter to the company.
Facebook - Facebook is in talks to buy Norway’s Opera Software, according to a Reuters report. Opera is the maker of a popular web browser, but is said to be in Facebook’s sights because of its advanced mobile phone software technology.
