Berenberg analyst Robert Lamb attributes the selloff today in Benefitfocus to 2018 to guidance confusion relating to accounting changes and sees a potential trading opportunity. The stock in early trading is down 10% to $22.40. A reacceleration in new customer wins, positive product developments and deepening relationships with wider industry players indicates Benefitfocus is executing well in a challenging environment, Lamb tells investors in a post-earnings research note. The analyst lowered his price target for the shares to $29 from $36 and reiterates a Buy rating on Benefitfocus.
