Fibonacci divider and 5 waves

It anyone knew about Elliott , we could have used Fibonacci divider to show us the the top. This was a perfect wave .
Note how wave iv divided the entire wave into 0.618 : 0.382 ratio . A Fibonacci divider.
Now just hope this wave should not be retraced by more than 0.618 percent . If it does the we can assume this was an extended wave 5 which will put a cap on the stock for atleast double the time of its current wave up. Regards
