"Capital One's Ambitious Acquisition Plans and Regulatory Hurdles"

Capital One's acquisition of Discover Financial Services could potentially lead it to become more like American Express, with a focus on a large rewards program and a closed-loop system. This move gives Capital One more control over its credit card program, access to new financial technology, and a larger global role in the future of payments. The acquisition also aligns with Warren Buffett's investment strategy, as Capital One's stock is trading cheaply and appeals to his approach to investing. However, investors should consider various factors before investing in Capital One stock.
