This "big investor" is unknown to me and I had only seen the "trading activity". I have posted "estimated profit % earned" and not "profit % change". It may be less than 2%. Even 1% guaranteed profit everyday from "single big investment" is not justified because the "big investor" is moving the stock markets alone.
Price Waterhouse Coopers(PWC) are the Auditors for "Satyam Computers". But PWC were not able to detect the sophisticated & well-engineered fraud from "Satyam Computers". Price Waterhouse Coopers are among the most reputed & biggest Financial Auditors in the world. Satyam computers is a classic example for "Ponzi at stock markets" because investors were made to believe of "inflated profits" which attracted new investors at Stock markets. There is high possibility there are thousands of "Satyam Computers" listed on worldwide stock markets.
