Something I found interesting in the shareholding pattern.
There were a bunch of companies - Seahorse, Highpoint, Abhirati, Newtree, Cyberbetix, Ashtavakra, Bluepearl who all took huge positions in FY11/FY12 - All of them are Mumbai based real-estate or trading companies. These have steadily offloaded over the last few 5 years at different rates of return (See Price field). These companies disappeared from the holding in Dec '17 completely and then came the big crash.
Interestingly LIC made its entry with a huge position in Mar '13 and is now holding the bag with a rather large position.
