I think it's hard to understand in economics. It's easier to understand on psychology.It's a kind of panic or a sense that the world economy is just not in as good shape as we thought and so everybody is chasing everybody else.

It may be that the U.S. stock market starts to rise if people think it's gone far enough.

Nobody really knows what the market is going to do, but it sure looks like we are going to have a lot more volatility.

I think the Chinese are really amateurs when it comes to running markets.

I think oil prices are down for two reasons. One is, there is a lot of supply. There is a lot of supply because the U.S. now produces a lot of oil and there is a lot of supply because the Saudis seem to want to produce a lot of oil, maybe to punish the Iranians and the Russians.

I think that the feel that maybe China is slowing down means it will be buying less from Africa and Latin America. That means Procter & Gamble and Coca-Cola will sell less in Latin America and Africa. And so it is definitely related.

The stock market was relieved that the Fed didn't sound tougher, and the stock market seems to figure that everything they like about Donald Trump will come true, and everything they're afraid of about Donald Trump will not come true.
