So I've been looking at the financial sector lately, and honestly, there's some interesting opportunities if you've got $500 to deploy. Most people are obsessed with chasing AI and the usual tech darlings, but there are solid banking plays that deserve attention right now.

Let me break down two stocks to buy that caught my eye. First up is SoFi Technologies. This one started back in 2011 as a student loan platform at Stanford, but it's evolved into a full online banking application. What's impressive is how they've managed to keep growing despite being in a sector that doesn't get much hype from financial media.

Their mobile app is genuinely user-friendly, and they've built out a solid product lineup - personal loans, credit cards, investing products. The customer base hit 13.7 million by end of 2025, which represents 35% year-over-year growth. More customers means more people trying revenue-generating products. Revenue has been explosive too - grew 2,900% over the past five years and hit $4.77 billion in the trailing twelve months. What really matters though is they're actually profitable now, posting over $500 million in pretax income in 2025.

Then there's Nu Holdings, the parent company of Nubank. This is a massive mobile banking operation across Latin America - Brazil, Mexico, Colombia. They're doing exactly what SoFi did in the US but south of the border. Instead of traditional branch banking with high fees, they offer everything through a mobile app and cards. It's resonating with customers - they've got 106 million active users as of Q3 2025.

The numbers here are wild. Last quarter, revenue jumped 42% year-over-year to $4.2 billion, and net income came in at $783 million. That's the kind of growth profile where you see a company scaling profitably, which usually means even bigger profit expansion ahead.

Both of these are among the fastest-growing banks globally right now. If you're looking at stocks to buy with limited capital, these two deserve consideration. The banking sector might not be sexy, but growth is growth, and these companies are proving they can execute while maintaining profitability. Worth adding to a watchlist if you haven't already.
