Hi Michael, welcome to the forum.
You are right when you say "It seems sometimes like you don't even use stops at all since you stay in even when a stock drops quite a bit.", my stops are psychological, it all depends of the potential of each stock, for example, I can sell a stock if it drops just 10%, if I think that the stock lost potential to run, even if I see that it will not fall, just trade sideways, and, this was the case of WAVE, for example, and, I can hold a stock like HAYZ, that I bought at .01125 and yesterday touched .0061, about 40% below my buy price, because I believe that it will run to .026, so my stop is my confidence level in a stock.
"Is that the case and, if so, isn't that extremely risky?"
No, it isn't, because I know how volatile a penny stock can be, I don't know what is your knowledge level about penny stocks, but, I trade penny stocks since 1997, and, during the technological bulb, until 2002, I saw many times penny stocks run 500% in a matter of 5 - 10 minutes, good old times, so when I believe that a penny stock will run and I will make money, I hold even if sometimes it is 50% below my entry price.
If you still have doubts, just ask.
Have a nice day.
