Just remember the bigger the fish; higher is the chances of the survival of the fish and same holds true for the FIIs investment strategy in India.
As a thumbrule study the stocks where FIIs are increasing their stake or pick gems of the market where FIIs stake is on the lower side. These are the stocks which are still not on the radar of the FIIs. Such type of stocks in present market scenario are Persistent, Indusind, Drreddy, Wipro & Oberoi reality. Alternatively check the Top stocks in India and invest in a systematic manner.
However a word of caution is that if you are following FIIs than follow them in totality for entry and exit. Are you ready for this business strategy as Fiis are like rats which are first to leave a sinking ship.
