This is a high growth company in the high growth 3D printing sector that is becoming a bit crowded with competitors including DDD and newly announced IPO X-1. These stocks may have gotten overextended, as evidenced by deteriorating technical's and a 10.5% reduction in share price today. 5 Day is now below 13 day EMA, MACD negative turn on Jan 25, with accelerating slide, and a spike in volume is confirming the trend. All of this is coincident with a flat overall market, as reflected in the SPX . If SSYS drops 10% in a flat market, it is likely to be highly and disproportionally vulnerable to a 3-5% market correction that many believe is overdue. Stock could test Dec 28 $ 73.33 bottom, before resuming its growth after the expected market correction.
SSYS may be a medium term buy, but the short term risk reward is biased to the downside.
