I do not like them. Trust me if I was worried about the stock I would of pulled the trigger myself. Stop losses can hurt you as well. I used to use them all the time and would get stopped out of a stock to watch the market makers turn and run it into the close. Have no idea how many times that happend to me back in the day.
$CETX unless you are a day trader, Stop Loss IMO not recommended, the float is small. If you plan on CETX putting STOP Mights, might as well just sell at the high or have a trailing stop of .10 cents
