him as "Amitabh Bachchan of the Stock market". Grow More Research and Asset Management, with the financial assistance of associates, when the BSE auctioned a broker's card. He actively started to trade in 1986. By early 1990, a number of eminent people began to invest in his firm, and utilize his services. It was at this time that he began trading heavily in the shares of Associated Cement Company (ACC). The price of shares in the cement company eventually rose from 200 to nearly 9,000 due to a massive spate of buying from a set of brokers including Mehta. Mehta justified this excessive trading in ACC shares by stating that the stock had been undervalued, and that the market had simply corrected when it revalued the company at a price equivalent to the cost of building a similar enterprise; the so-called "replacement cost theory" that he had put forward. During this period, especially in 1990–1991, the media portrayed a heightened deified image of Mehta, calling him "The Big Bull". He was covered in a cover page article of a number of publications including the popular economic magazine Business Today, in an article titled "Raging Bull". His flashy lifestyle of a sea facing 15,000 square feet penthouse in the tony area of Worli complete with a mini golf course and swimming pool, and his fleet of cars including a Toyota Corolla, Lexus LS400, and Toyota Sera were flashed in publications. These further exemplified his image at a time when these were rarities even for the rich people of India. In criminal indictments later brought by the authorities, it was alleged that Mehta and his associates then undertook a much broader scheme, which resulted in manipulating the rise in the Bombay Stock Exchange. The scheme was financed by supposedly collateralised bank receipts, which were in fact uncollateralised. The bank receipts were used in short-term bank-to-bank lending, known as "ready forward" transactions, which Mehta's firm brokered. By the second half of 1991 Mehta had earned the nickname of the "Big Bull", because he was said to have started the bull run in the stock market. Some of the people who worked in his firm included Ketan Parekh, who later would be involved in his own replicate scam.
