With a MS in Statistics, go for a Ph.D in economics...You'd be the hero of the econometrics class.  You'd surely have all the dumfugcks there give you a stare as though Einstein just graced them with his presence. 

On a more serious note, if you've had financial classes (especially Options), apply for trading positions or trading strategists roles at IBs (example: quants).  Don't go for the prop shops as you'd end up regretting, just stick to aiming for the hedge-funds and major IBs out there.  You'd get an above average decent starting salary with a MS in Stats.  When you do find a job, Send me your first bonus for helping you make the BIG bucks!
