This comparison of High Yield (via $HYG) against TSY of similar maturities ($IEI). As the ratio starts to turn down, market gravitates towards risk off environment. Notice how it touches the trend line but doesn't break thru it.
As you can see on the chart, $IEI/$HYG has broken through the ichimoku cloud, which has not happpened for over a year. This could indicate a major pullback in all markets. I would definately keep positions small and stay very careful this week. Good Luck!
