iShares Barclays 20+ Year Treasury Bond ETF (NYSE: TLT ) If the sell-off in stocks continues it will likely lead to more money flowing into bonds and TLT. The concerns that shook investors included a Chicago PMI that fell by the most since 2008, several poor earnings reports, wage increase-spooked inflation fears, a major Portuguese bank exposed as on the verge of a major bailout, Argentina's default and a jobs number that was not as strong as the headline appeared. Combine that with a seemingly oversold RSI and the odds of the market bouncing back this week are high.
