We outline how hospital purchase order data can be used by investors to track medical device companies using three case studies provided by a Neudata-listed alternative data provider. Specifically, we look at how purchase order data could provide value for investors across three medical device companies: Penumbra (PEN), Intersect ENT (XENT), and Zimmer Biomet (ZBH). We also share our views on the comparative advantages and disadvantages of different providers offering this type of data.
