Although we don't think shareholders should simply follow insider transactions, we do think it is perfectly logical to keep tabs on what insiders are doing.

Amgen Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the Executive VP, Jonathan Graham, sold US$3.3m worth of shares at a price of US$242 per share. That means that even when the share price was slightly below the current price of US$246, an insider wanted to cash in some shares. As a general rule we consider it to be discouraging when insiders are selling below the current price, because it suggests they were happy with a lower valuation. However, while insider selling is sometimes discouraging, it's only a weak signal. It is worth noting that this sale was only 40% of Jonathan Graham's holding.
