3D Systems and Stratasys Have a Frightful Fall

Every day, Wall Street analysts upgrade some stocks, downgrade others, and "initiate coverage" on a few more. But do these analysts even know what they're talking about? Today, we're taking one high-profile Wall Street pick and putting it under the microscope.

No two ways about it, yesterday was not a fun day to own 3D printing stocks. Over the course of six-and-a-half trading hours, shares of 3D printing pioneer Stratasys (NASDAQ: SSYS) fell 6.8%, ExOne (NASDAQ: XONE) was down 2.8%, and German rival Voxeljet AG (NYSE: VJET) decreased 0.6%. The biggest drop of all occurred at 3D Systems (NYSE: DDD), where the stock stumbled 23.7% over the course of the day.

And far from reassuring investors that all is still well, Wall Street added to the panic with a series of downgrades, which is where our story begins.
