Warren Buffett’s Berkshire Hathaway Has Held Moody’s Corporation (MCO) Since 2010

Moody's Corporation (MCO) has maintained its position as a core holding within Warren Buffett's Berkshire Hathaway portfolio since 2010, representing a 13+ year conviction in the ratings agency's business model. The continuity of this position—initially valued at $754 million across 28.4 million shares—underscores Buffett's confidence in the company's structural advantages and pricing power within credit rating markets.

The inclusion of MCO among Berkshire's long-term holdings reflects the stock's alignment with Buffett's investment criteria: defensive characteristics, stable cash flows, and entrenched competitive moats. Ratings agencies benefit from regulatory barriers to entry and endemic switching costs, making them secular performers regardless of economic cycles. The multi-decade holding period signals patience with modest but reliable returns rather than speculative appreciation.

For equity markets, this narrative reinforces confidence in Financial Services sector fundamentals and the sustainability of yield-generating equities. Buffett's continued MCO exposure also suggests comfort with credit markets and economic conditions stable enough to support ongoing rating activities and fee generation.

Sector implication: The MCO holding exemplifies portfolio diversification into non-bank financial intermediaries, which provide recession-resistant revenues and typically trade at premium valuations due to monopolistic characteristics. This signals positive sentiment toward fixed-income and capital markets infrastructure.
