Question: when is the best time to sell exxon shares???? 

Answer: When it no longer meets the original reasons you invested in the first place.\n\nWhen it exceeds your "asset allocation" in its class. Consider (if that's the case) selling 25%, 50% etc of your total holdings.\n\nThe key to successful investing is having and maintaining a good "asset allocation". This is more important than getting the right stock or mutual fund.
