Listen to the news

The fact that multiple 4D Molecular Therapeutics, Inc. (NASDAQ:FDMT) insiders offloaded a considerable amount of shares over the past year could have raised some eyebrows amongst investors. Knowing whether insiders are buying is usually more helpful when evaluating insider transactions, as insider selling can have various explanations. However, when multiple insiders sell stock over a specific duration, shareholders should take notice as that could possibly be a red flag.

While insider transactions are not the most important thing when it comes to long-term investing, logic dictates you should pay some attention to whether insiders are buying or selling shares.

4D Molecular Therapeutics Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the Co-Founder, David Kirn, sold US$737k worth of shares at a price of US$12.87 per share. That means that an insider was selling shares at slightly below the current price (US$14.49). 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. While insider selling is not a positive sign, we can't be sure if it does mean insiders think the shares are fully valued, so it's only a weak sign. It is worth noting that this sale was only 3.8% of David Kirn's holding.
