This is a pattern to watch for now. Just think, many will be knowing that Fridays could be a dangerous day to sell or short. Instead of getting out of the market for the weekend many may think that will be better to stay invested or cover their shorts. I believe that will add more price stability in the long run. Many companies release bad news on a Friday, but PTSC is changing that. IMO, this company really is helping to bring something new to the market place in more ways than one.
