I am an individual investor. I try to limit my stock portfolio to companies and products I understand. I am a consultant in technology / Internet, so most of my stock investing is in that space. I believe in the benefits of combining non-correlating assets. I implement most trades through options, often LEAPS, with the occasional spread or straddle. I use Peter Hoadley's tools for portfolio optimization and options strategy. I spend a lot of time in Excel. I'm reading Graham and Dodd. When not investing, I enjoy skiing and flying. I'm a private pilot, and glider pilot. I have two sons in their 20s. I live in a 1700s house that has a cooking fireplace, so I've been learning Colonial cooking techniques (pics http://www.flickr.com/photos/timothyshea/sets/72157621824250901/). I learn a lot from Seeking Alpha. I enjoy the articles, and the diversity of comments.
