Guys if I sell some of my TECO that I bought for .08 and then turn around and buy the stocks right back for cheaper would that show up as a lose in my bottom line?  I'm not sure if that works or not but I bought and sold some options at the beginning of the year so my short term investments are up for the year and techinically I could wipe those earnings out by selling my higher buys of Treaty.
