Maxim Group analyst Allen Klee defended Stamps.com Inc. on Friday and said that the stock's sizable selloff in the prior session was "an overreaction." Stamps.com's stock slid more than 10% Thursday after the Trump administration released a broad array of proposals, which included a plan to potentially privatize the post office. "We think it is unlikely that changes to the USPS would negatively impact Stamps.com and would use the pullback as a buying opportunity," Klee wrote. "Any potential changes made to USPS that would improve its financial condition and maintain its competitive position versus other carriers would be a positive to Stamps.com, in our view." Klee has a buy rating and $320 price target on the stock, and he recommended that investors look at the recent pullback as a buying opportunity. Stamps.com shares are up 71% over the past 12 months, while the S&P 500 has gained 13%.
