i've been trading full time for about 2 mos. and i'm learning a lot everyday. My strategy is to get in at the lowest price avail. and if the price goes lower i buy more at the next lowest price to effectively bring down my avg. price per share. sometimes its neccessary to hold a position over night and in rare cases for a couple days. so far so good. today TIVO lost .55. I can't figure out why. The earnings reports don't come out til next week and i can't find any news headlines. someone dropped 100k shares earlier today and the volume was at least at a 2 month high. any1 know why this happened?
