Fixed Income One Year and Six Month Total Return

This is one year and also six month total returns  on some monthly payers I own. $10254.01 = 2.5401% total return, etc for each entity. CMOPRB is a single security paying $0.105 per share each month. Doubleline is Grundlach's new ship. The rest should be obvious. 

The six month shows more detail, especially how investment grade fixed income mirrors the stock market but with less volatility.

I suspect that DBLTX doesn't price all its mortgages daily, meaning less liquidity. They may be holding to maturity like Bearhanky is doing.

I am using Vanguard Short Term Treasury VFIRX/VFISX and and also PIMCO's MINT, neither shown here, as money market fund substitutes. MINT has a duration/maturity under one year and had total return just under 1% over the past 12 months.
