What else is driving corporate earnings?

Chung:  Earnings are likely to be better than expectations for a while. Retail investors need to remind themselves that public companies represent some of the most dynamic innovation in our country. Netflix was recently added to the S&P 500. This is a company we invested in many years ago at $5 (Thursday's close: $181.65). Everyone knows it now. It's an example of zero international exposure, but pure innovation. Most of what it does is an old business of watching movies delivered by mail. Now they're moving to the Internet. This type of innovation is why U.S. stocks are very attractive now.
