Square stock pops 4% as its underdog Cash App nears "profit puppy" status

Be there or be Square... Not too bad. Square stock jumped 4% yesterday on strong quarterly earnings, which included a 46% jump in sales to $1.3B. Square is Jack Dorsey's mobile payments processing company that makes money in 3 key ways (same Jack as the one running Twitter).

• Seller Ecosystem: You've probably seen Square's sleek tablets at craft coffee shops, or swiped your card through a little white reader plugged into an iPhone at a taco truck. Sellers can easily process transactions, and Square gets a cut of each swipe.
• Square Capital: Offers loans to Square's sellers and small businesses, then collects interest and fees.
• Cash App: Offers peer-to-peer money transfers (like Paypal's Venmo), and collects fees on credit card transactions. It also offers a debit card and launched stock trading in October.

When the underdog comes in clutch... While small business card processing is Square's primary biz, its consumer-facing Cash App has been a star in its earnings:

• Cash App's revenue increased 147% from last year to $361M in the 4th quarter.
• Monthly users doubled from 7M to 15M in 2018, and hit 24M in 2019.
• For reference: In April 2019, Venmo reported having 40M yearly users.
