I own only about 16 individual stocks. Sadly no Costco, although its certainly done well for years. It's a fairly minor BRK holding.
I do own BRK.B shares.
As of today, I have a profit in every one of my 16 individual stocks, and that's not counting years of dividends I've collected in all but BRK. Sears hasn't paid a dividend since 2005. What a loser it's been!
