A recent experience and additional observations have created a very jaundiced view of a group of traders who take advantage of less experienced folks. They are poachers with all the negative connotations of that term. Let me explain with an example
I had a short position in RUTH. I stupidly placed a stop lost / limit order to protect my capital from a price increase above my limits. I absent-mindedly left that stop loss order open over night … it was snapped up first thing when market opened at about $0.25 above the next trade. I looked at RUTH trading history and there are several of these very odd very early trades way above the market … Poachers taking advantage of stupid people like me.
Not to self: Never leave stop loss orders open overnight and especially in thinly traded stocks like RUTH.
