Marginal buyers have a big impact by adding a lot of liquidity, but I'm not sure they manipulate prices that much, given that if they ever tried to move prices far from the margin they would cease to be marginal buyers.
But again, I don't think we're talking about a concerted effort to manipulate prices. We're talking about the effect that particular marginal buyers just so happen to cause.
