I can't believe it. Guys, is there any regulations under ASX to forbid a major trade like this from occurring? From what I have seen, there was a major trade of 26 mil shares at around 1 pm right? and possibly from UBS on the speculation of privatisation? What I am annoyed are people who put on the stop loss also sold down, when it reached its lowest of $2.39. This is ridiculous, I was wondering who the hell keeps dragging the price lower from $2.90 to $2.70 and down to $2.39 and flip back at $2.56 closing price. Does that mob know how many people set the stop loss and that is what causing the total of volume traded today to 34 mil shares. What a jerk, because people are setting the stop loss and because of one irresponsibility of a major share holder, triggered other millions of loss from other shareholders too. I didn't set it but I also trust that many remainder in this stock are frustrated to see today price. We all hold it for a reason and a trust on this stock, and $2.90 is still low from our expectation and I believe that no on of the remainder wanted to see today prices.
We shall see the news, but I am very eager to know is it illegal to trade this massive volumes of shares on the stock market? I thought this sort of trade only available before 10 am between brokers or between major shareholder with the Corporation? I just think that it is not right to unload it within normal asx trading hours ,due to the risk of uncertainty and without expectations from the news can cause the triggered of stop loss from everywhere causing hundred of traders losing money for no reason. Any thought please?
