Dav3J - I believe that in a quiet time like now the assumption is that lower prices also lead to more Buys, as well as the occasional freaked out seller.
Sometimes they are happy to drive the price up to try and attract some momentum investors but it seems that the rest of the time when they have run out of ideas and have a seller's shares burning a hole in their figurative pockets they simply knock the price down (assuming of course the seller has said they'll take less because they obviously want out).
The assumption that Lower price=> buys we know does not always hold true - if there are no news eyes looking at the stock then it doesn't matter if the price is up down, left or right. It does matter to holders who are regular as clockwork checking the SP. It seems a fairly reliable assumption for us at the moment though as we have a mature audience who know the true value of the company, but some of which are sitting on the sidelines, waiting for the cheapest buy back prices.
Ditto increasing the price - the assumption that this leads to more sellers is not necessarily true if the price was up 3% for the last couple of days then chances are trading types are hanging on for even higher highs (it depends where you are in relation to the moving averages no doubt if you ask an exponent of TA for 9-year-olds). Ditto it can act to draw more buyers in who sense that "this could be the end of the overhang this time, cross fingers".
Thus the SP does not simply behave as a spring system with buying/selling pressure acting as a proportional restorative force upon the share price - this would yield simple harmonic oscillation, perhaps damped a little by the reaction of those who have seen multiple cycles before. Some of the mechanisms above give positive feedback which can make the system unstable and drive the price to new semi-equilibrium positions.
For example when a rerate happens the sudden increase in Buying pressure actually means the MM's essentially give up trying to hold the price back and it drives off, in this case upwards, with the MM's simply churning back out to the market the small number of shares they just managed to buy in. The movement up draws in new money which accentuates the process and it gains an upwards momentum. This process may only stop when a sufficiently large seller steps forward to say that they wish to cash out - at this point the MMs have a tool with which to control the price. They sell short, charging top whack, and the move the price back down to the chagrin of the seller. That is why you rarely see soft upward landings.
