That is, the buying dries up and there are no big bidders. Then some of the bidding MMs start backing off and one or more MMs start lowering their offers and may even initiate the selling by hitting the bid. But it's not important how the selling starts, because the idea is to get the ball rolling which will inevitably attract other sellers and trigger stop orders. Once the price reaches a certain level (e.g., technical support) or larger or more bids start appearing then the MMs on the selling side quickly back off on the offer. Of course, all the while that the price was going down the MMs are also buying from the sellers. The price almost as quickly gets back to where it was when the selling began, and there may be less volume on the way down than on the way up. This type of move is also not characterized by having large volume at the bottom since the reversal is very quick and no one is selling very much. In this scenario it is clear that MMs are trying to replenish their inventory. Your scenario of a large seller dumping stock is different. First of all, a large seller is likely to be selling into strong buying (perhaps at resistance, or this seller may be the one creating the resistance). They rarely try to sell when the buying dries up, because they know what their selling will do to the price. But if this big seller is to sell when there is no buying interest then the price will drop, perhaps in a similar fashion to the running the stops scenario. However, volume would be increasing as the price fell until it reached "support" where there is the greatest volume and is an indication of the bottom. At this point the price is likely to go up again, at least for a bounce, and if the seller has more to sell then the cycle starts all over again. So the major differences between the scenarios from my observations are in the volume of the selling and how quickly it reverses on low volume. And in the running the stops scenario the price usually continues higher in the previously established uptrend. ...tai
