There is the fact that - people have had a lot of confidence that the Chinese leadership could fix what is wrong with their economy so it wouldn't have ripple effects around the world. I think that confidence is being shaken by how difficult it is for them to manage their stock market and their currency.

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 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.

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

I think what the Fed fears is that, if Donald Trump gets big tax cuts and big spending increases that take effect right now, when the economy is close to full employment, they will have to raise rates more rapidly.

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

At some point, people may decide that the U.S. stock market has fallen enough. After all, the U.S. economy seems to be getting better, that what happens in China is not going to have that devastating effect on car sales here or how many people buy Apple phones or what happens at - how many people shop at Wal-Mart.
