Opportunity Loss Problem Solver

I am considering a 'buy-on-dip' strategy for *mid150bees*. I have a total of ₹1 lakh, and the current P/E ratio of *mid150bees* is 30.7. I am waiting for a 9% drop. How many days do you think I should wait starting today? If *mid150bees* does not fall by 9% within that period, I should go ahead and invest at the prevailing P/E ratio to avoid an opportunity loss.
