Nu Holdings (NU 0.09%) is one of the largest digital banking platforms around. It only operates in three countries within Latin America, so investors here might not be too familiar with the business. However, don't let that discourage you from taking a closer look at this monster winner.
Had you invested $10,000 in this fintech stock three years ago, here's how much you'd have today.

Nu shares have risen at an astronomical pace

Key Data Points
Strong fundamental gains have paved the way
It's no surprise that the underlying business has done exceptionally well. Nu currently has 127 million customers (as of Sept. 30), an 81% jump from three years before. This is only possible because the company introduced financial services solutions that are in huge demand, serving a part of the world that has a large unbanked and underbanked population.
This has driven immense revenue growth, to the tune of 219% during that stretch. And Nu is very profitable, posting a superb net margin of 18.8% last quarter.
It's not reasonable to expect past returns to continue, but Nu stock certainly deserves a closer look.
