Come on guys - do we have to have a conspiracy theory every time someone sells shares.There has to be a seller for every buyer and we all have different perceptions of value or there would be no market.
Why is it always someone is selling low so he can buy cheaper later on instead of the far more likely motive of buying high to support prices so can sell later on (or support his netwealth and allow him greater purchasing power in margin/cfd purchases).

Do you not think when he purchases back shares he will merely drive prices back up again

Do you not think that in a flurry of buying activity far greater than what we are accustomed to this would be an extremely foolish time to try drive down prices
Do you not think that a person sophisticated enough to drive the prices down would not be aware that any day or hour now O+G shows will probably be announced and could undo all his work whilst he is left with a depleted shareholding
Do you not think it is more likely to be ST traders who have made their money
Or even the sophisticated investors who bought near 100m shares less than 6 weeks ago for 7.2 and are quite happy with a 20-25% return in that time
Not saying it doesnt happen just that it is extremely unlikey in these particular circumstances
