I agree with your point that Mr. RK Damani likes to stay away from limelight.
But what surprised me is this: -
His investment in VST Industries is one of his major holdings. I think he is invested in VST Industries since early years of 2000, I mean he is holding it for very long time and to top it he is slowly increasing his holding. Just give a thought about these two points. Holding it for long time and increasing his holding plus this holding is a major portion of his investment portfolio. Would one not like to participate directly in the growth of such company? What better way to participate in the growth than becoming a board of director either by himself or by making some one from his side as a member board of directors? Board of director rarely give interviews to media or make posts on social media. Most of them stay away from publicity.
Am I missing something here?
