Bikash,
Please address me as Raunak. Drop the 'Sir' please.
Now coming back to your query. Dear, we can never know when FII's will pull out their money. Hence, don't pay attention to these news or rumors. If they will, we will come to know through price structure. Till then, its better not to assume. October is cyclically a corrective month for India and the Global markets. This is just a possibility. This is not certainty. Hence, trade with stop losses and you will be fine.
