It is not uncommon to see companies perform well in the years after insiders buy shares. Unfortunately, there are also plenty of examples of share prices declining precipitously after insiders have sold shares. So before you buy or sell Alpine Immune Sciences, Inc. (NASDAQ:ALPN), you may well want to know whether insiders have been buying or selling.
What Is Insider Selling?
Most investors know that it is quite permissible for company leaders, such as directors of the board, to buy and sell stock in the company. However, rules govern insider transactions, and certain disclosures are required.
We would never suggest that investors should base their decisions solely on what the directors of a company have been doing. But equally, we would consider it foolish to ignore insider transactions altogether. For example, a Columbia University study found that 'insiders are more likely to engage in open market purchases of their own company’s stock when the firm is about to reveal new agreements with customers and suppliers'.

Alpine Immune Sciences Insider Transactions Over The Last Year
Over the last year, we can see that the biggest insider purchase was by Independent Director Robert Conway for US$80k worth of shares, at about US$8.03 per share. That implies that an insider found the current price of US$8.58 per share to be enticing. While their view may have changed since the purchase was made, this does at least suggest they have had confidence in the company's future. If someone buys shares at well below current prices, it's a good sign on balance, but keep in mind they may no longer see value. Happily, the Alpine Immune Sciences insider decided to buy shares at close to current prices. The only individual insider to buy over the last year was Robert Conway.
