Shares of PayPal (NASDAQ:) continued on their torrid run higher in late April after the digital payments provider delivered first quarter numbers that broadly underscored the company’s healthy long term growth narrative. Meanwhile, global retail sales are moving higher by a few percentage points every year given population growth, increased urbanization, and inflation. Consequently, as the commerce market grows at 15%-plus rate over the next several years, PayPal’s payment volume and revenues should rise at a similar 15%-plus pace.
