Benny went to a good school and he took at least one physics class.
Benny knows that once a big heavy truck starts speeding up, then it's really hard to slow the truck down. Of course, once a big heavy truck starts to stop/slow down, then it's really hard to get it going forward again!
So once the sell volume brings the xyz price down, it takes a little while for xyz to start moving up again.
In case Benny wanted for xyz to go up, then he would just need to have the buy volume exceed the sell volume by just enough. Then, with his large volume, he would create a big heavy truck speeding up. It would take a little while for the truck to slow down in that opposite case.
The absolute best part for Benny is in tomorrows blog. :)
