During the day, TCS shares gained nearly 2% to push its m-cap to over R2.61 lakh crore. During the afternoon trade, TCS commanded a m-cap of R2,61,357 crore about Rs 833 crore more than RIL's market value of R2,60,524 crore. A marginal fall of 0.12% in the share price of RIL also acted as a catalyst.

Incidentally, the year-to-date gains of both RIL and TCS are also almost similar. While the software major has gained 15.37% in 2012, the Mukesh Ambani-controlled entity has moved up 16.59% since January 2012.
According to data from Bloomberg, ONGC, with a market valuation of R2.27 lakh crore, stood at the third position, followed by ITC (R2.23 lakh crore) and Coal India (R2.21 lakh crore). The m-cap of a listed company corresponds to the cumulative market price of all its shares.
