I just looked up my stock. I own 1000 shares. It's worth. 33 cents each. I dunno how to get my 330 bucks though... I could use that. I need corn.
This might help:

As for how the stock market works (not quoted, but you asked in an earlier post) stock (share) prices fluctuate depending on whether people are buying or selling shares. Buying drives the share price up. Selling drives the share price down. People will generally buy or sell based on how the company, and the price of its shares, is doing. If the company is wildly profitable, then people buy. If the company is losing money, people sell.
If I were in your shoes right now, before I did anything, I'd look at what the company, and it's share price, is doing. If the price is on the way up, you might want to wait for a while, because the value of your shares is also going up. If it's on the way down, it's likely a good time to sell, because your shares will lose value. HOWEVER, you also want to look at where the price is trending. If it's trending UPWARD, then it's a good idea to leave your money there for a while, even if, in the past few weeks, the price has dropped. It's going to go up again. If it's trending downward, but over the past few weeks, it's gone up, then it's probably time to sell.
Consider, too, the value of your shares today compared to the value of your shares when you bought them. If you bought at $0.25 per share, and they are now worth $0.12 per share, you're going to end up losing money if you sell now. BUT, if the price is trending downward, SELL NOW, because you might lose your shirt (and you without a shirt is NOT a sight I want to see!). If it's trending up, WAIT, because you'll want to try to make back your losses.
Hopefully that's somewhat clear. But, do me (and yourself!) a favour. Do NOT take my advice. I know enough to be dangerous. Talk to a broker before you do anything.
