Part of it's a relative. US is an exporter of oil, so we net benefit as an economy from higher oil. Other countries are importers, so the US not only looks better but on a relative growth basis it should outperform which means flows back into the US. As we worry about global growth, when growth is scarce, people buy growth stocks. The US stock market is a growth index. So it's coming out of the rest of the world back into the US. It's a rotation story.
