So, buy on line if it's cheaper. There's your opportunity. If you have confidence in PEN and it's objectives, then that should be a no brainer. Either way, it's an opportunity to top up.
By buying on market, you help support the price and get rid of some of the sellers, and soon the price will confidently return to 13c+ which, in turn, will give others more confidence to take up the SPP which, in turn, will help PEN meet its objectives and ultimately benefit us shareholders. And, if you buy on line, then you stand to make an extra 0.006c per share!
Today's volume of over 7M shows that that there are many doing just that.
