<prompt> Human: I am NOT a stock trader. Ive just happen to own some stock for a company which I think seems fairly volitle. The stock regularly fluctates between 18.00 and 20.00. At times there are higher spikes Ive seen it at 24.00 and lower troughs 15.00 or so. Im wondering if it would be profitable or wise to have a rule that causes me to sell at 20.00 and repurchase at 18.00. It would be with 5,000.00 worth of stick Im small potatoes really and the eTrade fee is something like 20.00, which is negligible. Or is this just day trading stuff that would make me go bonkers? Im sure others have seen this kind of behavior with a stock that fluctuates between two values. - Thank you for the input - I think someone below said it best when they said, If you could make money this way, everyone would be doing it!. Plus the added tax implications bother me.Thank you all for your input.  <response>: If it was easy to get rich doing this, everybody would do it. You should find better ways to determine your companys value.
