We haven't seen the fundamentals change as of yet but if you believe the chart says all then bail. There was a short article in Barron's recently more than likely by someone that is short or has connections to shorts but that is Wall Street for you, where a lack of integrity seems to be the norm.
The outgoing CEO has been accused of posting on this message board but the one post that was supposedly his was totally factual.
I would hold here but it could hit recent low's in the 8's or if there is bad news it will go lower.
All that said the new CEO handles himself very well on the calls and definitely seems to know what he is doing. Now the appointment of the daughter to COO is questionable. All IMHO.
It's a very volatile small cap stock. 20% isn't a huge move for this. I generally play the swings on MED and consider it a buy at 10.50 or less, and a sell at 13-14. My own valuation on this is roughly 13.00 if earnings stay in line this quarter.
I definitely would not sell here. A lot of bad press and manipulation has this down farther than it belongs IMHO.
