RE:Take profit? Or hold..It depends where you hold the stock; in an RRSP, or TFSA. If in a straight investment account you would have to consider Capital gains tax which could be substantial.(depending on # of shares you hold). If in a RRSP or TFSA why sell as the dividend is tax free. Also are you in for the short term investment/return or long term ?In any event a 15% return on your initial investment is a good return and, currently, I know of no stock where you can get such a return today.
The decision is yours depending on your investment strategy and tax bracket!
