And naturally having glimpsed examples now and then of gross manipulation and outright theft in other stocks you extrapolate this to explain what you don't understand about why this stock moves the 'wrong' way.
If the entire market is as rigged as you seem to think it is why do you even bother to invest? Because if that were indeed really the case then being not in the know you can only lose.
I'm not saying there isn't plenty of isolated cases of manipulation particularly in the low float stocks momos seem to love. But most of that appears to come in sudden up spikes for no apparent reason that'll drive a stock up 50 - 150% (which we then short) before it slowly returns to earth. Or take a CHNR which saw its trading volume jump from 6,000 a day to 2m two days BEFORE they announced a reverse merger. There it's easy to quantify the manipulation (and the SEC is looking into CHNR).
But for the little penny moves in GGR? No one cares. It's just 'noise'.
