Not that all these manipulations are absent in stock market but there are rules which mitigate it to the barest minimum even when you flout the rule, there are appropriate punishments to be meted out which is why when they put out data from that end, people take not because its right but there are not enough substantive evidence to invalidate those figures.
The rules you refer to don't really do much.... institutions continue to rig the markets they are active in, just on a level it doesn't appear to be manipulation. It's not about pumps and dumps, but about multi year plans to control markets.
From time to time you read about banks being fined for manipulating this or that market, which the governments aren't too unhappy with because it provides them an opportunity to fine banks hundreds of millions of dollars.
Banks on their turn know that they are going to get fined so they already calculated that into their budget, collateral damage that is called. Making billions in profits but only pay a few hundred million in fines, not a bad deal, right?
