Piper Jaffray analyst Troy Jensen downgraded 3D Systems (DDD) to Underweight after his channel checks indicated the company saw a "significant slowdown" in printer demand in Q2. Demand for 3D "was more challenging than ever," Jensen tells investors in a research note. He believes HP's (HPQ) Fusion Jet launch is "pausing demand" and attracting existing 3D Systems channels to partner with HP. The analyst lowered his price target for 3D shares to $10.25 from $12. Jensen tonight also downgraded Stratasys (SSYS) to Neutral from Overweight.

In the firm's Q1 letter to investors, David Einhorn's Greenlight Capital disclosed new long positions taken during the quarter, including taking stakes in HP Inc. (HPQ), Penn Entertainment (PENN) and Roivant Sciences (ROIV). In the letter, the firm stated that it established a new "medium-sized position" in Penn at an average price of $22.69 per share, arguing that "were the market to credit PENN with merely 15% of DraftKings' value, [Penn's ESPN BET] segment alone would be worth $20 per share." On HP Inc., Greenlight stated that it had established an initial position at an average price of $30.76 per share, adding that it believes "that we are, at a minimum, on the cusp of a normal PC refresh cycle, which should drive earnings above estimates." On Roivant, Greenlight said it had established a "small long position," adding that "in addition to an exciting pipeline, ROIV has a strong track record of positive trial results and successful monetization of pharmaceutical assets." Einhorn's Greenlight Capital also noted that it reduced its Teck Resources (TECK) long position into strength during Q1 and that the firm bought a "small position" in Liberty Global (LBTYA) during Q1.
