Listen to the news

We'd be surprised if Arrowhead Pharmaceuticals, Inc. (NASDAQ:ARWR) shareholders haven't noticed that the Independent Director, Mauro Ferrari, recently sold US$493k worth of stock at US$56.39 per share. That sale was 14% of their holding, so it does make us raise an eyebrow.

The Last 12 Months Of Insider Transactions At Arrowhead Pharmaceuticals

In the last twelve months, the biggest single sale by an insider was when the Chairman, Christopher Anzalone, sold US$1.5m worth of shares at a price of US$11.76 per share. That means that even when the share price was below the current price of US$57.95, 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 3.5% of Christopher Anzalone's holding.
