Have Insiders Sold Natera Shares Recently?

Simply Wall St · 1d ago

Some Natera, Inc. (NASDAQ:NTRA) shareholders may be a little concerned to see that the Chief Financial Officer, Michael Brophy, recently sold a substantial US$1.3m worth of stock at a price of US$426 per share. That sale reduced their total holding by 16% which is hardly insignificant, but far from the worst we've seen.

Natera Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the Lead Independent Director, Roelof Botha, sold US$18m worth of shares at a price of US$239 per share. That means that even when the share price was below the current price of US$389, an insider wanted to cash in some shares. When an insider sells below the current price, it suggests that they considered that lower price to be fair. That makes us wonder what they think of the (higher) recent valuation. However, while insider selling is sometimes discouraging, it's only a weak signal. We note that the biggest single sale was only 6.1% of Roelof Botha's holding.
