RIL, TCS, Infy and SBI common thread in India's m-cap milestones

Reliance Industries (RIL), Tata Consultancy Services (TCS), Infosys and the State Bank of India (SBI) are the only four consistent names in the list of top 10 companies when India hit the milestone of $1 trillion, $ 2 trillion and $ 3 trillion in market capitalisation. India first hit the $1 trillion m-cap mark in May 2007. Over a span of 14 years, the top 10 list has undergone considerable change with names like Reliance Communications, ONGC and NTPC disappearing from the list and new names like Kotak Mahindra Bank and Bajaj Finance stamping their authority. The current list and the list when India hit the $2 trillion milestone in July 2017 are fairly identical as they share seven companies.
