In just a month?s time, the market capitalisation on the Bombay Stock Exchange (BSE) has jumped from Rs 46 lakh crore to around Rs 55 lakh crore, a growth of around 19%. This could easily be one of the most prosperous months in the annals of Indian stock market history, when nearly Rs 8.9 lakh crore were added to the overall market wealth, in just a month.

And making most are the large industrial groups who have also seen a tremendous jump in their collective wealth.

A study by The Financial Express reveals that top industry houses have seen their wealth grow by 25% over the past one month itself.

For the top ten industry houses, the growth was over Rs 2.72 lakh crore over the past one month.

The two Reliance groups owned by the Ambani brothers Mukesh and Anil have been at the forefront of this jump in wealth. While Reliance Group of Mukesh Ambani saw the highest jump in absolute values, a growth of almost Rs 1 lakh crore, brother Anil Ambani’s Anil Dhirubhai Ambani Group (ADAG) saw the highest percentage change (42.65%) in the market capitalisation in a month. For ADAG, there has been an overall escalation of prices in their key group companies.

Reliance Energy saw a near doubling in price, growing to Rs 1,533.65 from Rs 766.65, a month ago.

The announcement of Reliance Power going in for an IPO and high earnings estimates on the basis of its EPC business and real estate projects seem to have gained investor fancy.

This happened despite several leading equity research houses advocating a ?sell? recommendation on Reliance Energy. Others, Reliance Capital and Reliance Communication, gained 54.25% and 35%, respectively, over the month and also aided ADAG gain in market capitalisation. The overall positive sentiment in the metals and steel businesses saw the OP Jindal, Sterlite and AV Birla Group market capitalisations grow.

For the Tata Group too, overall positive price movement in its key companies, Tata Power, Tata Chemicals, Tata Steel and Tata Teleservices see an across the board jump in share prices.

The group saw the third highest growth in market capitalisation in absolute terms.
