I'm not sure what thread you are referring to, hc, but there were a couple this week, that were entertaining.
"What investing prowess?" - Apparently Vanguard's Consumer Staples ETF, VDC, has bested BRK-B by 317 basis points per year since inception, 1/30/2004. That one, along with VIG, are now on my potential buy list for review once prices become a bit more rational.
"WEB value formula" - IMO, that one is goofy beyond words, LOL!
