I just checked my FICO score (I am provided my score every month from my credit card company) and it dropped 50 points in one month. I haven't opened any new accounts, missed any payments or increased my debt so should I be concerned? Could this be indicative of idenity theft?
There is a new model of FICO called FICO 08 that's coming out. If you have been on another persons credit card as an authorized user (but not as a joint account holder) your score may drop. Also the new model places more emphasis on having different kinds of credit such as installment and revolving accounts.
And yes, you should get a complete printout so you can check for identity theft.
