Insiders Who Sold Rigel Pharmaceuticals Made The Right Call As Market Cap Slides By US$97m

Simply Wall St · 12/12/2025 12:47

Over the past year, insiders sold US$424k worth of Rigel Pharmaceuticals, Inc. (NASDAQ:RIGL) stock at an average price of US$21.39 per share allowing them to get the most out of their money. After the stock price dropped 11% last week, the company's market value declined by US$97m, but insiders were able to mitigate their losses.

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.

Rigel Pharmaceuticals Insider Transactions Over The Last Year

The President, Raul Rodriguez, made the biggest insider sale in the last 12 months. That single transaction was for US$200k worth of shares at a price of US$21.93 each. So it's clear an insider wanted to take some cash off the table, even below the current price of US$42.05. 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 5.9% of Raul Rodriguez's holding.

Does Rigel Pharmaceuticals Boast High Insider Ownership?

Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. I reckon it's a good sign if insiders own a significant number of shares in the company. It appears that Rigel Pharmaceuticals insiders own 1.4% of the company, worth about US$10m. While this is a strong but not outstanding level of insider ownership, it's enough to indicate some alignment between management and smaller shareholders.
