<<Yeah..... $2000 is what BRK (now BRK-A) was when I had $2000 in my IRA and passed it because it was crazy to buy one share of a stock with everything in the IRA.>>>

I hear you! I bought an A share (BRK then) for $6,950 after it rallied a lot from the $3500-$4000 range. And, yes, people told me I was crazy to spend as much as it cost to buy a good condition used car for ONE share of stock. One person told me I was buying a collectible not a rational stock investment at that price.

There were times I was seriously tempted to sell when it was clearly overvalued. It ran from $9,000 to $16,000 I recall pretty quickly—going from 25% undervalued to 25% overvalued in short time. How do you think THAT felt? Over time it didn’t matter at all. Same with the run up that prompted Buffett to swap a large chunk of Berkshire in return for Gen Re. If Buffett’s swapping his overvalued stock out—why should I hold? We’ve had periods like this one before. The lesson is it rarely, if ever, makes sense for LONG TERM holders who plan to own for many years in the future—to sell years early.

Not to be confused with what many here, including me, engage in: periodic “name your lumpy dividends”. Money you live off—you might peel off 2 to 3 years or more of “dividends” at these prices.
