The only reason you would want your currency to fall, if you could control it, is in order to get more exports.

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.

I think the one thing that's going on here is that people are saying, uh-oh, the Chinese economy might be slowing more than we thought and the government is having a hard time stimulating it again.

People have put a lot of faith in the government's ability to get growth going in China. People have this, what I think, illusion that there are six people in China who really have their hand on every button. And what we're learning is, it's a very big economy and they're not that good at it.

The only reason you would want your currency to fall, if you could control it, is in order to get more exports.

If the government can't get the economy moving again, they have a lot of fundamental problems.

There is also a concern that there is a lack of demand of oil. And so when commodity prices fall, it's good if you happen to be a consumer, but it's sometimes seen as symptom of a weakening economy.
