Some Atmus Filtration Technologies Inc. (NYSE:ATMU) shareholders may be a little concerned to see that the CEO, President & Director, Stephanie Disher, recently sold a substantial US$1.2m worth of stock at a price of US$45.25 per share. However, it's crucial to note that they remain very much invested in the stock and that sale only reduced their holding by 6.6%.

The Last 12 Months Of Insider Transactions At Atmus Filtration Technologies

In fact, the recent sale by Stephanie Disher was the biggest sale of Atmus Filtration Technologies shares made by an insider individual in the last twelve months, according to our records. So it's clear an insider wanted to take some cash off the table, even below the current price of US$47.37. We generally consider it a negative if insiders have been selling, especially if they did so below the current price, because it implies that they considered a lower price to be reasonable. 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. This single sale was just 6.6% of Stephanie Disher's stake.
