We do not have, nor have had, and never will have an opinion about where the stock market, interest rates, or business activity will be a year from now.
Our future rates of gain will fall far short of those achieved in the past. Berkshire's capital base is now simply too large to allow us to earn truly outsized returns. If you believe otherwise, you should consider a career in sales but avoid one in mathematics.
If I got any good ideas out of that or I think they're good ideas, I'll be glad to contribute them but the system will probably overdo some other things.
I wouldn't want to manufacture cigarettes. But if I owned - we do own Costco. Do they sell them? Yes. So I don't have a problem owning stock in that.

The approach and strategies are very similar in that you gather all the information you can and then keep adding to that base of information as things develop. You do whatever the probabilities indicated based on the knowledge that you have at that time, but you are always willing to modify your behaviour or your approach as you get new information. In bridge, you behave in a way that gets the best from your partner. And in business, you behave in the way that gets the best from your managers and your employees.

But Sir Isaac's talents didn't extend to investing: He lost a bundle in the South Sea Bubble, explaining later, 'I can calculate the movement of the stars, but not the madness of men.' If he had not been traumatized by this loss, Sir Isaac might well have gone on to discover the Fourth Law of Motion: For investors as a whole, returns decrease as motion increases.
