Warren E. Buffett, 2015 (TN)

5 to 8 securities can make up 80% of his portfolio. One position could be up to 30%. Having a concentrated portfolio works well for lazy people. Not that many stocks to track. Thinks about how much he could lose if he's disastrously wrong. No formal process or time frame for purchase decisions. Usually spend one month or so to do research. ................
