Warren Buffett’s Berkshire Hathaway is investing in Nu Holdings, a fintech company addressing the banking needs of a largely unbanked population in Latin America. Despite a recent 37% decline in stock value from its peak, Nu has experienced significant growth, with a 43% revenue increase and a doubling of customers since 2021. The company’s strong unit economics and potential for developing customer loyalty suggest an attractive investment opportunity, especially at a forward price-to-earnings ratio of 17.7, indicating a compelling valuation for long-term investors.
