Reliance Industries Ltd (RIL) has emerged as the biggest wealth creator in FY 09, generating Rs 1,51,400-crore, which accounted for over 15 per cent of the total wealth created last year, a study said.

Brokerage firm Motilal Oswal, in a study released today, said oil and gas continues to be the biggest wealth creator during the last six-years--the first three years led by state-run ONGC and the next three by RIL.

"Reliance Industries has emerged as the biggest wealth creator for the third time in a row. It has created Rs 1,514- billion worth of wealth contributing 15.6 per cent of total wealth created in FY 09," the study titled '14th Motilal Oswal Wealth Creation Study' said.

The Mukesh Ambani-led company is the largest contributor of wealth for the third time in a row, while real estate firm Unitech was the fastest wealth creater since 2004, the study said.

Motilal said that Unitech's five-year stock price recorded a staggering compound growth of 122 per cent. Apart from RIL, home-loan lender HDFC, pharma company Sun Pharma, auto major Hero Honda and software exporter Infosys Technologies have emerged among the top 100 wealth creators in the past 10-years.

"HDFC is ranked as the most consistent wealth creator by virtue of its 10-year price CAGR (compound annual growth rate) being the highest," the study said.

However, this year, mining firm, "NMDC has the unique distinction of featuring in both the biggest and the fastest wealth creators' list," it added.

The brokerage firm, however, noted that eight of the top 10 most consistent wealth creators are consumer-facing businesses with a strong franchise.

Sectors like FMCG and telecom are, however, in the fray of coveting the biggest wealth creator title and are edging out oil and gas firms.
