** Shares in NN Group NV NN.AS fall around 4% after Morgan
Stanley downgraded its rating on the Dutch insurer from
"equal-weight" to "underweight" and cut PT by 12% to 44 euros
** The broker says the company's solvency position is very
sensitive to financial market movements, especially mortgage and
sovereign spreads
** MS analysts believe that these sensitivities could make
the company's Dutch Life entity, which is the primary source of
cash for the parent company, more vulnerable
