After 18 months away from BDR I put an order for 500,000 at 18c last Wed. as ducks are now in a row for this stock to outperform.
I got to the top of the queue on Wed and got a few. On Thursday got another 7000 or so and on Friday got 1 share.
Friday was interesting as the stock traded around 19 cents all day until the close. Someone then decided to take out all the stock at 18.5 cents and one share at 18 cents on the close.
The only rational reason for this is that someone was willing to sacrifice some stock on the close to give the impression that the stock is weak and hopefully shake out a few more sellers during the following days. The fact that I was at the top of the queue and only got one share means it was a well planned move.
My sense is that there is a big buyer out there accumulating.
