A fag-end rally during Tuesday's session lifted the sensex by 204 points; it also pushed up BSE's market capitalisation to Rs 336 lakh crore or $4.02 trillion, a new all-time peak for the Indian market. One of the major factors behind the $4-tn milestone during the day was a strong rally in the stocks of 10 companies belonging to the Adani group that added more than Rs 1.2 lakh crore or about $12 billion to its market cap in just one session. With $4-trillion market cap, India is now fifth most valued market in world, data from various exchanges showed.
