You may be better to put in a trailing stop loss - instead of a sell target.
If you put in a sell target and the stock goes up - your stock sells and you settle for the profit.
My opinion - a better approach - when your stock gets close to hitting your sale target - if the chart still looks good - cancel your sell and put if for sell with a trailing stop loss of 10%.
That way if your stock goes up for the next 14 days - you get all those additional profits. If one day - while you are at work it drops 12% - your stock sells!
