Credit Suisse came up with the positive review of 3D printing companies and expecting that the sector will grow in near future and may exceed Wall Street’s expectations. As a result of this the shares of all 3D printing companies went up. Shares of 3D Systems shot up around 5.75%, another company Stratasys went up around 2.6% whereas ExOne didn’t show great results and went down around .77%. Should we start thinking of making some space for these companies in our portfolio?
