There are little things about the Market that continually annoy and frustrate,and we have an example here of someone selling 2,100 share for $893 on the Chi and pushing the SP down to 42.5c....and on the other hand 366 shares being bought on the ASX For $161 keeping the last sale at .44c....I can appreciate that sometimes these are the 'End' of an order....But how these subtle fluctuations play out and who they serve remain a mystery to me....to have your stock down by 10.5% for $893 is really irritating....And it's not a true reflection of what is really going on.
