I am a railroad Engineer with 30 years of investing experience. I predicted the crash in 2006 moving many of my assets to safer investments at that time. Bought back into stocks beginning in Dec 2008 a little early to buy and a little early to sell has been my bio. My Roth investments are up 200% not counting new contributions since March 2009. I look at present economic conditions to predict which companies will win in the future. Presently have been buying hdge, fsys, c, hdge because I believe there are opportunities in shorting companies whose quality of earnings is suspect and need the reverse accounting expertise. Fsys because I like the idea of $1 a gallon fuel and believe Saudi is the next to blow up causing $5 gas and large fuel users such as the US Postal service to make drastic changes in their fleet fuel options, could be the reason fsys is hoarding cash to pay for basic materials to be used in massive production increases coming forward. And C because it is cheap and it can borrow from the fed at 0% and loan it out at 4% plus.
