Explain how supply and demand influences the price of common stock. What other forces affect stock prices?

Demand and supply of a good or service influences its price and common stock is no different. If more people are demanding for a stock and yet the supply remains constant, the price of the stock will go up because people will be willing to pay more to acquire the stock as the stock is more scarce.

The same goes for supply, if there is a higher supply than demand, the prices will reduce because people will only be willing to pay less now that the stock seems to be in abundance.

Other factors that affect stock prices include;

my economy is bad lots of people are poor and lots of people are jobless and homeless

there was no passage listed but using the process of elimination i'd say it was d. the high economy would do the opposite. i don't see how low prices would affect it. high unemployment is possible but i feel d is the better answer.
