For obvious reasons, it wouldn't be a good idea for me to give investment advice. The use of stops can be subjective, depending on whether you are trading or investing.
However I'm happy to explain how I use stop losses from a trading perspective.
I NEVER trade without a stop. I use it to protect my capital when the trade goes the wrong way - it happens often - and I'm usually happy when it gets hit, that's what it's there for. When a position goes into profit then I have the option of moving the stop to break even or to profit, using a combination of support/resistance, fib levels, targets, etc as a guide. Each trade/position is unique requiring some kind of flexibility.
If you have a specific stock in mind then I'd recommend finding the CHARTS forum and requesting a chart with some key support levels and opinions from the growing group of respected chartists who are more than happy to share and help. There you'll find charts on many stocks and on the broader market in general.
