Diamond Hill Large Cap Concentrated Fund stated the following regarding Aon plc (NYSE:AON) in its Q4 2024 investor letter:
“As valuations have continued rising and the economic cycle has gotten relatively long in the tooth, we’ve thought carefully about where and how we are exposed to more cyclical stocks. As such, we initiated just three new positions in Q4: Berkshire Hathaway, Aon plc (NYSE:AON) and Waste Management.
Aon is one of the world’s largest insurance brokers and benefits consultants, and one of the only companies with the breadth of skills and knowledge to cater to and effectively serve large clients with complex risks. The insurance brokerage business produces steady, non-discretionary growth and requires minimal capital. Aon’s shares have recently taken a breather as investors digest the company’s recent acquisition of NFP — which we believe will add value over the long term. We consequently capitalized on an attractive valuation relative to Aon’s peers to initiate a position in the quarter.”
