I've seen this market participant a few times this week. It might have been him on the Monday morning opening that bought the stock up to 1.60 with approximately 100,000 shares and subsequently let it fall all day to 1.50. Yesterday, this person clearly wanted to mark the stock up on the close. He was on the bid for less than a minute at $1.51 for approximately 55,000 shares...then he reduced it to less than 2,000 shares. He could have bought plenty of stock at 1.53 or better in the last 10-15 minutes before the auction but decided to load it all in at the close at 1.62....Strange and irrational operating in my view....arguably manipulative.... Evidence for that is what has transpired this morning - it is back to 1.53. The stock is clearly awaiting an update. I think its a good short term trade to buy it in the low 50's punting on an update next week - Patience I guess!!
