As retirement is evidently on again in 2012, let's not forget to keep an eye on HYG (high yield corporate credit).
The start of 2012 has led to a pretty significant decoupling of the S&P (equity) and HYG (credit), which begs the question which is right - as both are "risk on" asset classes, does S&P have a significant correction ahead, or does credit just have some catching up to do?
Over the past few years, it's been equities that have gotten out ahead of themselves.
