deepeshmodasia,
It has been a very illiquid share, and any moves up or down have been quite swift, which is why I have been happy to hold on. Maybe the move to CREST will help, but generally the pattern has been to drift sideways or down in the absence of any news.
I think that the key issue is going to be the next stage of the EU trading scheme, it is probably the uncertainty caused by the over supply of credits earlier in this year, leading to a crash in the price of CO2 credits, that is holding this share back.
There was a suggestion sometime ago that not only should the amount of free credits allowed by each country be reduced, that industry should also pay for these via an auction or similar. Any announcements along these lines or extension to other industries such as the airline or construction industries would obviously be very favourable to Agcert, by creating further demand for CERs.
So to answer your question, I have no idea what will happen in the short term. Although from past experience, whenever any news does comes out it will probably be too late to catch any rise (or fall) if you are not already a holder.
