There is not much to get excited about in the fixed income market at present with Govt Bond ETF's yielding 1.6% (Yield to Maturity) at best. By heading up the risk curve you can get yourself an extra 1% or so by selecting investment grade corporates. Most funds seem to have slightly increased duration to add a few basis points.
CRED seems to be a bit of a stand out. YTM of 2.56% at present on effective duration of 6.6 years. Our risk measure is "Volatility" or the standard deviation of the daily price changes annualised. That figure says that CRED is at the higher end of the risk spectrum but by no means the highest.
