Dentsply Sirona (NASDAQ:XRAY) is the leading manufacturer of dental consumables and equipment. The stock sold off due to distribution problems involving fellow Parnassus Fund’s holding Patterson Companies. We believe these issues are temporary, so we used the weakness as an opportunity to add Dentsply Sirona to the portfolio at what we believe is an attractive valuation.
