Malls and Retail Store Commercial Mortgage Backed Securities at High Risk

Deutsche Bank has reported increased defaults in commercial mortgage backed bonds tied to malls and retail stores that they underwrote in 2012 and 2013; the bank is suggesting investors short the BBB- rated portion of the 2012 Markit CMBX price index, known as the series 6, which they say is tied to these investments; their analysis sees these bonds with pre-crisis attributes which successful investors shorted to avoid losses.  Source
