Shares of 3D Systems (DDD) have been trading higher in 2017. In the previous update, I noted that 3D Systems might be following a Gartner Curve: Is 3-D Systems (DDD) Following a Gartner Curve?I still believe in the long-term bullish outlook for DDD, but in the short to medium-term, the technical picture still has a lot of sideways and potential bearish factors to consider. Let's take a look at the daily chart.DDD Daily Chart 1/24(click to enlarge)Bullish-Neutral:- 2016 was basically a bullish year in the beginning going from 6.00 to almost 20. It turned into a sideways market after holding under 20.00 in April. Therefore, I would say it is bullish-neutral.- Note that the consolidation is somewhat of a triangle.- A break above 18.00 could break the triangle. A break above 18.60 would break the October high and therefore introduce a higher high, which would reflect a shift from bullish-neutral to just bullish.Resistance:- Before getting ahead of ourselves with the breakout projection, let's note the resistance under 18.00.- There is the triangle resistance.- Also we see the bullish momentum slowing as the RSI shows a bearish divergence with price. What to anticipate:- I think at this point we should look for some short-term pullback at least towards 15.00. - We might want to consider picking up this stock if price falls back to 13.50 area. Here, a triangle based on an elliott wave count of (a-b-c-d-e) would be complete.- But, if price can hold above 15.00, it could be a good sign as well. - If price holds above 15.00 and heads back towards the triangle resistance, it would represent a failed swing to the triangle support, which hints at the potential of a break above the triangle resistance.
