Warren Buffett Sells Half His Nu Holdings Stake – Should Investors Be Worried?

Nu Holdings (NYSE: NU), the company behind Latin America’s largest digital bank, is experiencing some major shifts as big-money investors rethink their positions. While the company has been on a strong growth streak, recent stock price swings and changes in institutional investments have left many wondering: Is Nu Holdings still a fintech powerhouse, or is trouble on the horizon?

Big Investors Are Switching Up Their Bets

Some of the biggest names in investing have been making moves with Nu Holdings, and not all of them are sticking around.

On one hand, California State Teachers’ Retirement System (Calstrs)—one of the largest public pension funds in the U.S.—just bought an additional 1.1 million shares, bringing its total stake in Nu Holdings to 1.4 million shares. This suggests Calstrs is betting big on the future of fintech in Latin America.

But not everyone shares that optimism. Warren Buffett’s Berkshire Hathaway—one of Nu Holdings’ earliest backers—decided to slash its stake in half, cutting its holdings down to 40.2 million shares. While Buffett himself hasn’t explained the move, it’s raising questions. Is it just routine portfolio management, or does Berkshire see warning signs?

Stock Price Rollercoaster: Should Investors Be Worried?

Nu Holdings’ stock has been on a wild ride. It climbed 24% in 2024 and has already gained 3.8% in 2025, but recent volatility has rattled investors. Just last week, the stock plunged 7.66% in a single day, reminding everyone that fintech stocks can be incredibly sensitive to economic conditions.

Despite the price swings, Nu Holdings is still growing fast.

Massive Growth, But Not Everyone Is Impressed

The company’s latest earnings report showed some serious momentum:

• Net profit skyrocketed by 87%, reaching $610 million.
• Revenue jumped 50% to $2.99 billion, although it missed Wall Street’s expectations of $3.29 billion.
• Customer base surged to over 114 million users across Brazil, Mexico, and Colombia.

Nu Holdings isn’t slowing down either. The company has already hinted at expanding into a new country by the end of the year, marking a major milestone in its growth strategy.

The Road Ahead: Bright Future or Warning Signs?

There’s no doubt that Nu Holdings is a fintech powerhouse, but challenges remain. Rising nonperforming loans, tougher competition, and economic uncertainty could impact its long-term success.

For now, the company remains one of the fastest-growing fintech firms in the world. But with major investors making big moves and stock prices fluctuating, it’s clear that Nu Holdings is at a crossroads—and the next few months will be crucial in determining its future.
