Hi nick08, nice to hear from you. :) Only you can determine what a realistic selling price is for you and your needs. Don't sell any investment at a price that is solely based on a price that someone else says is a realistic selling price. Don't buy any investment solely based on someone elses comments that it is a great investment. Do your own DD and make your own investment decisions. Determine what your financial needs and situation are. Any sale for a profit is a good sale no matter what the profit amount is. :) The return of your money that you invested is paramount and is always more important than the theoretical return that you may or may not realize on your investmment.
It is critical that you learn to read, create, and understand stockcharts. Go to stockcharts.com for more information about how to read, create, and understand stockcharts. IMVHO, trading without an understanding and use of stockcharts can be very dangerous to your financial health. Don't trade or invest without them. I never make any trades or investments without constantly consulting my intraday (ID), daily, weekly, and monthly stock charts. :) I review and/or create at least 30,000 to 50,000 charts a year or more. This includes constantly reviewing many times a day my charts and those of others.
Good luck on your investments.
Bob
