DDD is demonstrating a strong bear trend since end of August.
Currently, it's in A2 bear set up (two legged move to EMA in a bear trend) with a good-looking reversal bar (although it's bullish, but still a valid set up as it was a second failed attempt to break above 20 EMA).
Stops will be around 40.45 area (MA), first target - 36.5
In case if set up triggers below 38.70 - should work all the way down to 34.00 where where we had a strong support line and where we have a lot of bull stops.
Fundamentally, it looks like DDD has been a bit overbought with all this 3D printing hype and extreme volatility of the DDD stock itself.
