If you want safe, stocks probably aren't your best choice. Mutual funds are safer... but you might not be able to get into any with only a few hundred dollars.
Why would you want a stock that won't change much?
How much do you have to invest? It's hard to do stocks with a few hundred. A few thousand is much better.
Personally I just watch some stocks that make money and look for relatively low price per earning ratios. When I find a combination of a low PE, a company that makes money and is trading lower than I believe it should, I buy some shares and immediately put a sell order for more than I bought it at.
For example:
On Sept 17th I bought CFC (CountryWide) for $19. I immediately placed a sell order for $21.25 that went through on Sept 19th. Then I rebought it at $18.17 yesterday and I currently have a sell order for $20.25
I also like buying FLEX every time it goes below $11.00 and selling it when it goes above $11.50
Sometimes the stock jumps up and I can dump it in a couple days. Other times it goes down but since I believe in the company (or in CFC's case, I believe the financial institutions will not let CFC fail), I will hold onto it until it rebounds.
Because I keep my portfolio diversified, I can afford to hold onto some of these for 6 months or longer if they drop instead of taking the loss.
