The effect of sales on stock prices

[rfnel]

Hi All

This is probably a very dumb question, but I know next to nothing about the stock market, and I want to get my ducks in a row before risking any money. (Also, if my terminology is wrong, feel free to correct me.)

I would like to know if the total sales of a company over a given period affects the value of its shares. Why I am asking this, is because I was looking at stocks in a newspaper this morning, and I noticed that one can purchase shares in our local (South African) breweries. To me it would make sense that a lot of alcohol (as well as food) will be sold over the festive season. Therefore, if share prices are affected by sales (which I assume could increase the total value of a company) I would think that those shares would increase in value over the festive season. I'd appreciate it if anyone could tell me if what I'm thinking is sensible. Thank you.

Regards,
