Yes, I placed market order. Putting in limit orders won't help though I think. The volatility is not of that kind.
For example one company tanked 30% in one week after announcing they lost a major contract (LQDT). Same thing with Ruger - they couldn't keep up with the hype sales growth of the past years.
After those swings they tend to hold steady. Again, just 10 stocks for half a year, so anecdotal at most. Some others aren't going anywhere, and yet others have been steadily climbing. In aggregate roughly break-even.
It's just basic small company behavior I guess: relatively small events can cause huge swings in value, both inherent and perceived. Guess that's one of the reasons why there seems to be a small cap excess return in the longer run.
