To tie into DaddyCoop's take, I've also gotten tired of the games that go on with penny stocks. It has driven me nuts the way people act before pr's, after pr's...it seems as if they don't use their heads and are so afraid of penny stocks in general that they really shouldn't be investing in them at all. If they're that scared, just find some mutual fund...
I've said it before, although none of us really want to be flippers all day long, you have to at times or you'll be left behind while the rest of the crowd, in fear, jumps in-and-out of certain stocks, making the prices go up and down based on their own actions! If people were simply more level-headed about this kind of investing in general, then penny stocks would probably be pretty solid. Instead the stocks' movement is so heavily based on the emotions of the investor...that's what drives me crazy, but it's also what makes it possible to have crazy gains in one hour.
I think that if something jumps over fifty percent in an hour or two, unless there's a short sqeeze, you need to start paying really close attention to taking some profits...protect your capital at the very least, but leave the rest in there in case pps jumps 180%.
