Who Has Been Selling Amphastar Pharmaceuticals, Inc. (NASDAQ:AMPH) Shares?

In this article:

We’ve lost count of how many times insiders have accumulated shares in a company that goes on to improve markedly. On the other hand, we’d be remiss not to mention that insider sales have been known to precede tough periods for a business. So before you buy or sell Amphastar Pharmaceuticals, Inc. (NASDAQ:AMPH), you may well want to know whether insiders have been buying or selling.

Do Insider Transactions Matter?

It’s quite normal to see company insiders, such as board members, trading in company stock, from time to time. However, most countries require that the company discloses such transactions to the market.

We don’t think shareholders should simply follow insider transactions. But equally, we would consider it foolish to ignore insider transactions altogether. As Peter Lynch said, ‘insiders might sell their shares for any number of reasons, but they buy them for only one: they think the price will rise.’

Amphastar Pharmaceuticals Insider Transactions Over The Last Year

CEO, Chief Science Officer & Director Yongfeng Zhang made the biggest insider sale in the last 12 months. That single transaction was for US$892k worth of shares at a price of US$20.48 each. That means that even when the share price was below the current price of US$22.40, an insider wanted to cash in some shares. While sellers have a variety of reasons for selling, this isn’t particularly great to see. When an insider sells below the current price, it does tend to make us wonder about the current valuation. Please note, however, that this single sale was just 2% of Yongfeng Zhang’s stake. Notably Yongfeng Zhang was also the biggest buyer, having purchased US$643k worth of shares.

All up, insiders sold more shares in Amphastar Pharmaceuticals than they bought, over the last year. The sellers received a price of around US$19.61, on average.
