This Insider Has Just Sold Shares In Castle Biosciences, Inc. (NASDAQ:CSTL)

Investors may wish to note that the Independent Chairman of the Board of Castle Biosciences, Inc., Daniel Bradbury, recently netted US$79k from selling stock, receiving an average price of US$62.94. On the bright side, that's just a small sale and only reduced their holding by 0.4%.

Castle Biosciences Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the Chief Business Officer, Bernhard Spiess, sold US$2.0m worth of shares at a price of US$49.97 per share. That means that even when the share price was below the current price of US$61.30, an insider wanted to cash in some shares. We generally consider it a negative if insiders have been selling, especially if they did so below the current price, because it implies that they considered a lower price to be reasonable. While insider selling is not a positive sign, we can't be sure if it does mean insiders think the shares are fully valued, so it's only a weak sign. It is worth noting that this sale was 77% of Bernhard Spiess's holding.
