I have been investing in individual stocks and ETFs for a bit over 4 years. I became interested in the topic just a few short weeks before the big crash so its been quite an experience. Prior to that I had invested in low cost index funds of various types. My education consists of a BS and MS in chemical engineering so my stock interests tend to gravitate toward this area. I have been employed at one of the Department of Energy National Laboratories for most of my career.
