Basically the same principal applies . to sell before the Drill. In the case you have mentioned whilst there may not be as large a fall if there was a Duster the Voyager share price has risen a lot recently so it is still risky and I would not risk it myself.The other point with Voyager and STU for that matter is that there is not only a risk of a Duster but also the risk that Any discovery will not be large enough to have a sizeable upward impact on the share price . There are in effect 2 risks with these so called 'better asset cover companies ' Best wishes B2
