JPMorgan analyst Paul Coster upgraded Stratasys (SSYS) to Overweight from Neutral citing a favorable risk/reward profile following the stock's 65% year-to-date decline. The maker of 3D printers can reduce operating expenses while sales of high-end professional and production machines will likely return to 15% annual growth in time, Coster tells investors in a research note. There is near-term earnings risk, however, from declining Makerbot sales and soft end-market demand, the analyst cautions. He has a $42 price target for shares. Stratasys closed yesterday down $1.78 to $28.95. Its peer 3D Systems (DDD) closed down 81c to $12.35.
