The boost followed a meeting with Square's chief financial officer, Sarah Friar, and two of the company's investor relations team members, Stacey Fineman and Nikhil Dixit.
"Management emphasized Square's ability to win market share driven by its breadth of unique technology ... and a massive and growing addressable market," said Kumar in a note.
"Over the last several quarters, Square's winning strategy has been displayed through its continued traction with large merchants through new omni-channel capabilities, stable take-rate and low transaction loss yield, while maintaining high merchant acceptance rates. Based on our meeting, we believe such trends will continue," Kumar said.
"Square's approach to P2P differentiates from PayPal's Venmo, where Square utilizes Square Cash as a bank account given customer's hold an account balance and can utilize Square's debit card to make purchases. Square collects interchange on the debit card transaction and also offers a loyalty program, a newer concept for debit cards," the analyst said.
