If you got them for $138, then well done - a bargain, sell them immediately
Otherwise...
You ask an apparently simple question.
Not wishing to pour cold water, but it raises many others, such as :-
How long you are intending to hold them and how much profit you are aiming for.
Is this a day trade, position trade or what ?
Have you set a stop loss ?
Why didn't you buy them last September at 80p support ?
Why didn't you wait for a break above 140p ?
etc etc.
