Is he also a director in Suzlon?????
While we recognise the investing acumen of any individual, by looking at how his picks have done, we tend to ignore the role of liquidity. Big ticket investors can very easily cause a jack up in the price of the stocks they pick up thanks to their financial might. Thats when they become "operators" from investors......and as all literature on investments would tell you, its better to stay away from "operated" stocks, we should also not place too much trust on others' acumen beyond a point.
I have no clue about Mr. Dhawan's stock picking skills. He may be a wonderful investor, I dont know......but we have to be a bit cautious while we ape him.
