The Tata group now commands the highest market capitalisation followed by the Mukesh Ambani group, following a big drop in the price of the RIL Stock. There have been some significant changes in the market wealth report card of India Inc over the past year. A glance at the latest market-cap of leading business houses shows that during last one year, other than the Jindal group, both the Reliance group of companies were the only business houses which saw a decline in their market wealth.

While the ADAG group has been the biggest loser, with a 44% decline in the market capitalisation, the market capitalisation of the Mukesh Ambani-led Reliance companies declined by 21%. The O P Jindal led Jindal group lost 14% of its market wealth.

The Tata group on the other hand emerged as the biggest value creator with a 23% jump in the market-cap of its 28 group companies. Experts believe issues of corporate governance led to a derating in a couple of the ADAG companies.

In contrast, the outstanding market performance of a number of Tata firms have pushed up the market valuation of the Tata Group. ?The Tata group has seen significant wealth creation for shareholders partly because of the inorganic growth in firms like Tata Steel and Tata Motors, ? said Deven Choksey, MD KR Choksey Securities.
