Another great post Kent. I agree with your views ten fold..
BH b shares are a top drawer stock, I dont care if it tumbles 100 in a day. Its quality and top shelf. As Philip Carret said: "I dont have sense enough to figure out when to go into cash, so we're always fully invested.." AUI is one security I have taken on board. As you have stated this is quality and day to day price movements should be realised as second to the quality and management of this company. Carret also stated: "More fortunes are made by sitting on good securities for years at a time than by active trading."
