Berkshire Hathaway Inc. (BRK.A, BRK.B) may see lower investment returns following Warren Buffett’s departure as CEO, according to Morningstar.

The firm said Berkshire’s operating businesses have generally provided a “narrow moat,” while management’s ability to invest excess cash from those businesses at returns above its cost of capital historically supported a “wide moat” rating.

Morningstar said that track record “has gotten thinner over the years.” Berkshire’s size now requires increasingly large acquisitions or stock investments to make a meaningful impact, while the pool of attractive opportunities has become more limited.

Can Greg Abel Replicate Buffett's Capital-Allocation Edge?

With Greg Abel taking over as CEO, Morningstar expects Berkshire’s investment opportunities and returns to be lower than in the past. The analyst said Buffett is expected to continue advising Abel on investment decisions. 

Morningstar also said Berkshire’s “huge and growing sums of capital” will ultimately limit its ability to generate outsize returns.

The firm has a “Narrow” Economic Moat and an Uncertainty Rating of “Low” on the shares. The firm also said Berkshire’s operating businesses continue to provide competitive advantages, particularly its insurance operations, which generate low-cost float. However, Morningstar has seen “slippage in some of the moat sources” supporting several of Berkshire’s main businesses.

Another user said, “$BRK.B This is perhaps the cheapest hedge you can find against your super charged AI stock portfolio. When the market crashes, Buffett’s huge cash pile will pick up the quality stocks on the cheap. It is like buying a leveraged cash position.”
