Insiders At Howmet Aerospace Sold US$134m In Stock, Alluding To Potential Weakness

Simply Wall St

Over the past year, many Howmet Aerospace Inc. (NYSE:HWM) insiders sold a significant stake in the company which may have piqued investors' interest. 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 would consider it foolish to ignore insider transactions altogether.

Howmet Aerospace Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the Executive Chairman & CEO, John Plant, sold US$126m worth of shares at a price of US$157 per share. So it's clear an insider wanted to take some cash off the table, even below the current price of US$174. 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. We note that the biggest single sale was only 22% of John Plant's holding.
