I recall a while ago someone much more knowledgable than I explained why "stop losses" should not be used on venture companies. It seems obvious to me that's what happened today.
Some individual(s) with the particular capability saw the opportunity to dip down and trigger stop losses and thereafter letting normal market conditions prevail saw the stock rebound to more conventional levels.
Perhaps a repeat of the relevant instructional information would be relevant here. For we longs it is perhaps not as significant. My sense is that people with stop losses are perhaps playing a little closer to the edge and are taken advantage of.
Onward and Upward.
