When a stock goes up...the 22 rule

As an investor what should you do when a stock goes up by 8-10% of its value? Look at the timing. If it happened 4 days before a major announcement is expected, buy it. Watch it for 2 days(inclusive of the day you bought the stock), if the value still goes up, hold it, if the value goes down even by 2%, sell it.

How do I know? I really dont know. Please do not share this rule with anyone else.
