I have recently completed my masters and got a job in finance.  I deal with the study of investments.  Do you know much about finance?
I try to invest on my own, but I certainly haven't studied it to the same extent. I'm an engineer by trade.
Finance is an interesting subject.  You must know a bit about it to do your own investing. In my work we aim to price assets based on their risk level and their expected rate of return.
