Some ICU Medical, Inc. (NASDAQ:ICUI) shareholders may be a little concerned to see that the Chief Operating Officer, Christian Voigtlander, recently sold a substantial US$1.5m worth of stock at a price of US$107 per share. Probably the most concerning element of the whole transaction is that the disposal amounted to 100% of their entire holding.

ICU Medical Insider Transactions Over The Last Year

Notably, that recent sale by Christian Voigtlander is the biggest insider sale of ICU Medical shares that we've seen in the last year. That means that an insider was selling shares at around the current price of US$104. While we don't usually like to see insider selling, it's more concerning if the sales take place at a lower price. Given that the sale took place at around current prices, it makes us a little cautious but is hardly a major concern.

Does ICU Medical Boast High Insider Ownership?

Many investors like to check how much of a company is owned by insiders. We usually like to see fairly high levels of insider ownership. ICU Medical insiders own about US$152m worth of shares (which is 6.1% of the company). I like to see this level of insider ownership, because it increases the chances that management are thinking about the best interests of shareholders.
