For all the talk about SPY, VOO, VTI, etc, shouldn’t BRK be a part of the conversation?

There are a lot of perks about BRK that I really think is solid, particularly high quality companies, high MOAT, no dividend or expense ratios, private businesses (Geico, BNSF, etc) tons of cash, ability to buy companies for more growth, ability for stock buybacks, the list goes on.

I have VTI in my 401k, 457b 100%, but my taxable personal trading account is 100% BRK-B and has done very well. No 15% hit on dividends or expense ratios either.

How much have you allocated to BRK A or B in your portfolio?
