Stock share prices reflect the current price of a publicly traded company in the stock exchange, every second of the trading day. The price you see is actually the last transaction made for this stock and it is influenced by many factors such as news, expectations, market conditions, and fluctuations of supply and demand.
Overproduction caused farm prices to go down because when there is more than enough product, the demand goes down. Prices only go up when demand goes up.
When price goes up, Quantity supplied goes up with it, vise versa.
Gas prices are set by a supply and demand system. If something happens that effects that system then the price can go up or down. Gas prices will go up in the United States when a Hurricane hits the gulf of Mexico coast and the Oil processing plants and Oil rigs have to close down. The demand for the oil/gas goes up and the supply goes down so the prices go up. In a situation like the Swine flu gas prices are going down because the demand is going down while the supply is going up. As the demand for gas/oil goes up the prices will follow.

When the supply goes down, the price goes up because there is a shortage and there are less to be sold. When supply goes up on account of high prices, the price goes down because there is a surplus. If the demand goes up, the price goes up because people will pay more for it than usual. If the demand goes down due to the increased price, the price goes down.

The price of a stock moves up or down as per the Demand & Supply Theory. When there is a heavy demand for a particular share its price goes up. Similarly when there is an excess supply of a share then its price goes down. There are a lot of criteria that may impact the demand & availability of a share. Like its current quarter profit or high profile client loss etc...
