Don't know what other shareholders see when looking at the course of trades today but copied below is what I see.
A number of 0 volume trades and several trades with volumes around 500 to 800 shares.

Is anyone able to shed some light, especially on the 0 volume trades. I understand there may be some people rounding out their portfolios and reducing by 6 or 7 hundred shares but to have four or five people do it within an hour or so would be considered a little strange I would have thought?
