buyers v sellers, page-18

Today was hardly a tree shake...at most a gentle tree rattle as it was there to see in the pre open and people had time to think about their automatic stop loss settings. They also had time to think about why ot may go down a lot or not...tree shakes are more sudden usually.

My understanding is that a buyer will suddenly sell down some existing holding unexpectedly triggering panic and auto stop losses to trigger..sudden severe price drop...buyer then buys back quickly at lower prices.

Tree shaking is described in many stock websites arpund the world...eg just one from seeking alpha....

Tree shaking is bear raiding with the goal of buying low. Suppose a firm is in love with a particular stock, and they are going to take down a big chunk. It is in their best interest to tell the world what a great stock this is before they move in, right? Of course not. That might drive the price up before they buy. They will stay tight-lipped, or sometimes they will use the bear raiding techniques of creating fear to drive the share price down in shock-and-awe "how much worse is this going to get I better sell right now" scare sessions. Then, in the volume of the sell-off, and at discount prices, the firm will buy their shares. They "shake the tree" to see who will capitulate and sell them their shares.
