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%.Quote from makloda:
You fail to mention he also suffers 3% - 5% slippage on the way out, making the entire "moving the markets my way" exercise a zero sum game minus commissions.
Even 1% guaranteed profit everyday from "single big investment" is not justified because the "big investor" is moving the stock markets alone.
