Oh the good old WB quote. Having said that WB has huge resources behind him to make such a call. Had he be the average Joe I highly doubtful he can be greedy when things don't work in favorite.
At the end of the day he has said many many times for the average Joe, the best way to invest is going through an index fund and wait a long time (10-20 years)
Always enjoying your research by the way, thank you sincerely.
However if you look at the similarities SP performance of both KTD and JAT you must be wondering would Buffet actually be greedy looking at those miserable charts.........
