Wall Street Week on PBS. I've generally gotten pretty good investment advice. And I regret not taking some advice I heard on the show a long time ago. Early 80s as I recall, the guest was talking about a company called Berkshire Hathaway. It was a conglomerate that bought other companies' stocks. It was managed by some guy named Warren Buffett. The guest said he was a very shrewd investor, and he advised buying shares in BH, in order to benefit from Buffett's stock picking. The price was about $500 a share. I could have only afforded maybe 5 shares at the most, and I didn't want to take the risk. 35 years later, each share is priced at $246,000+. If I'd bought and held them, those 5 shares would be worth over $1.2 million, not counting dividends.
But I shouldn't complain. I've still been very fortunate.
