Subject: Question on 13-F
I was just glancing at the recent 13F filing for Berkshire. I calculated that the top 15 positions represent 92.63 % of the portfolio while the bottom 26 represent the balance. The seemingly massive 400 million share stake in KO is now less than 10% of the portfolio! Hard to wrap my head around that one:)
In addition, they seem to tweak the tiny positions from time to time. For example:
Lamar Advertising (LAMR) represents .06 % of the portfolio yet added to their position by 2.79%
Lennar Corporation Class B (LEN.B) represents .01 % of the portfolio and they added to the stake by .03%

So, my question is: why even bother with these tiny stakes? And to add/trim these positions seems like child play:)

Hope everyone is having a nice weekend.
