Shares of General Electric Co. rallied 0.7% toward a two-month high in afternoon trade Monday, after a bullish call from Gabelli & Co. Analyst Justin Bergner started coverage of GE with a buy rating, with a year-end 2018 stock value target of $21, which is about 42% above current levels. Bergner said it's easy for investors to forget the company's investment merits because of prior leadership's mismanagement of the power and oil and gas businesses, and not recognizing the worsening of its long-term care insurance business. "Notwithstanding some weakening end markets and mistakes of prior management, GE currently had the right leadership in place, with high quality assets in aviation and healthcare that underpin an attractive stock with a margin of safety," Bergner wrote in a note to clients. The stock, on track for the highest close since March 12, has tumbled 15.8% year to date, while the Dow Jones Industrial Average has gained 0.8%.
