best way to short a stock is to short an underforming stock at a lower high but wait for confirmation first. never short a stock just because the price seems too high because it can go higher. My estimate is that Exx can go as high as 215-220.
I can not see Exx continuing upwards without a correction. But I agree, going against the flow is very, very risky. I do not want to short just because it is overbought -Exx has run too far and too hard. And then there was the statement that 'n projected shareprice would be 18800 in a year's time. Maybe a short from 20650 to 20150 might pay of?
