Why 3D Systems Stock Just Rocketed 24.5%

Shares of 3D Systems (NYSE: DDD) stock are rocking 24.5% higher as of 11:15 a.m. EDT Tuesday, one day after the 3D printing machine maker reported blockbuster earnings for its fiscal first quarter of 2021. Analysts had forecast that 3D would earn only $0.02 per share (pro forma) on sales of $136.6 million in the quarter. 3D Systems sales, according to generally accepted accounting principles (GAAP) grew 7.7% year over year, but if you exclude sales from businesses divested in 3D's restructuring, to focus on its core strengths, those core businesses grew revenue 16.6% -- twice as fast as the headline revenue growth.
