tSorry if this has been asked before. I noticed that the an intermediate term treasury is down less year to date than the total bond market or non-treasury intermediate bond funds, Is this just due to the shorter effective duration or is it some sort of "flight to quality?" I have read that treasuries may have lower correlation with US stocks. Is it worth giving up some yield for better diversification?
