The fact that multiple Pinnacle West Capital Corporation (NYSE:PNW) insiders offloaded a considerable amount of shares over the past year could have raised some eyebrows amongst investors. When analyzing insider transactions, it is usually more valuable to know whether insiders are buying versus knowing if they are selling, as the latter sends an ambiguous message. However, shareholders should take a deeper look if several insiders are selling stock over a specific time period.

While insider transactions are not the most important thing when it comes to long-term investing, we do think it is perfectly logical to keep tabs on what insiders are doing.

The insider, Jacob Tetlow, made the biggest insider sale in the last 12 months. That single transaction was for US$860k worth of shares at a price of US$90.80 each. So we know that an insider sold shares at around the present share price of US$90.42. While insider selling is a negative, to us, it is more negative if the shares are sold at a lower price. We note that this sale took place at around the current price, so it isn't a major concern, though it's hardly a good sign.
