I think PCI could still do well, I would just say that the recent press comment adds to uncertainty over value of assets in algeria right now, which adds to uncertainty in general and in particular with regard to timing of deal conclusion. Uncertainty / risk go hand in hand with share price discounts IMO.
Considering the recent run in price in anticipation of good news there must be some potential for retracement ahead of what will hopefully still be very significant good news for PCI over the next 12 months.
Would I buy and hold PCI over the next 12 months? yes, but not my first choice
would I buy and hold expecting price to be higher next week? Probably not I prefer candidates such as RIFT, and OXB over the very short term, being already in both.
