Even my friend Bill Gates would agree. Buffett bought Dairy Queen, Gillette and Coke 30 years ago. That alone should not warrant blind following. That's a good thing. The best companies can go belly up.
Nothing is forever.
This is not about buying companies, its about making money. That should be the central objective. More on buy and hold . It would require a rather extraordinary change in profitability to justify that price. You don't have to be a financial analyst or accountant to make money in the market.
