relax- orbis investment is 2% of its portfolio, page-6

It's all so clear now. Share price falling - obviously it's traders shorting and instos buying. As has been pointed out, the fact that a single insto owns some shares makes this a sure thing. No fund manager has ever lost money or made a bad investment choice in the history of the stockmarket, and thank god for that. You'll also notice that if you turn the chart upside down it's in a definate uptrend :D
