Quote from Pabst:
BTW: Treasuries to corporates are widening also. Ominous.
Quote from doublea:
The effect of the flattening of the yield curve will be seen in financials before other sectors. In this case it will be more prudent to short financials(XLF) and long (SPY) in an appropriate ratio as per your risk. If the trade moves in your favour and the yield curve starts inverting, it makes sense to remove the SPY hedge.
