Ann: Share Purchase Plan Offer Booklet, page-246

One of the best trading or investing strategies i have read about is to have a plan before you buy the shares and stick to it, so for example you might have a plan to buy into a particular stock and sell a percentage of your holding to take a profit on the way up, if you have trouble doing this get some professional advice. Setting a stop loss at a point below your purchase price to protect against down side is a smart move, the important points are to protect your capital and dont fear taking some profit.
Just my opinion here is that a good number of holders took some profits at around $1.80 recently and they will not likely get their full SPP offering due to over subscription so if the SP drops to or below $1.30 the will be a lot of takers.
