I have been moving in and out of DDD since September. I use a 3D printer at my workplace and understand where this technology is going. How I play this one, since it has a lot of swings, is I established my base shares of 250 which I am holding long term. Depending how the stock is moving I will add. When it was getting hammered last quarter, I bought more. After they released the positive earnings, Staples news, and small acquisition, I bought more. This brought my total amount to 1100. When it shot up to 51 and some change this week I sold 600 at $50, when it went down again yesterday, I sold 250 more at $47. I will keep my base shares and look to add on this pullback.
I don't see this thing going to the 30's. For one I strongly believe in this technology and think the selling last quarter was way overdone. Also people bringing up the insider trading, that was included in the offering. Since the secondary offering price was $40, I don't see it going below that. Finally don't forget they are sitting on that secondary cash which they have clearly stated will be for an acquisition and we all know that this company loves to use those to increase revenue.
Don't listen to the naysayers. If you are unsure about it, why did you buy i in the first place?
