As you can see from the chart below, when you have your lines drawn, the market appears to "come to you".
So, we have a stock that's up against where it broke down from on Friday, we have a profit in it and we're not so sure about the overall mkts(See Dow Chart analysis) short term direction.
We also believe that should this one get over $3 again and show support there, we'd be able to get back in for what might very well be the start of a nice run.
If this one breaks down again and retests the prior $2.86 breakout area, well we've got a chance to buy in again at lower levels..should that be what we decide to do.
But it's really important to weight all aspects of holding a position vs. the potential to get back in after trimming.
