at any moment, the price is where the supply (seller) and demand (buyer) intersect. this occurs fast enough you don't see it as anything other than bid/ask. what moves it? news of a new drug, device, sandwich, etc. earning release, whether above or below expectations, or even dead-on, will often impact the price.  every night, the talking heads try to explain the day's price moves. when they can't, they often report "profit taking" for a market drop, or other similar nonsense. some moves are simple random change.
