The stock has tumbled 6.2% during its losing streak, the worst four-day stretch since it lost 7.0% during the four days ending Jan. 11, 2016. The after the company announced after Friday’s closing bell that its chief financial officer and two other vice chairs were leaving the company, and on Monday that it elected activist investor Trian Fund Management’s chief investment officer to its board. On Wednesday, analyst C. Stephen Tusa at J.P. Morgan, the most bearish of the 20 analysts surveyed by FactSet who are covering GE, cut his price target to $20, which is 13% below current levels, from $22, while reiterating his sell rating. "In our view, an activist heightens the risk that GE tries for a quick fix, like it has done in the past," Tusa wrote.
