Listen to the news

We wouldn't blame Griffon Corporation (NYSE:GFF) shareholders if they were a little worried about the fact that Ronald Kramer, the Chairman of the Board & CEO recently netted about US$10m selling shares at an average price of US$102. However, that sale only accounted for 5.5% of their holding, so arguably it doesn't say much about their conviction.

The Last 12 Months Of Insider Transactions At Griffon

In fact, the recent sale by Ronald Kramer was the biggest sale of Griffon 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 slightly below the current price of US$105. 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. We note that the biggest single sale was only 5.5% of Ronald Kramer's holding.

In total, Griffon insiders sold more than they bought over the last year. You can see the insider transactions (by companies and individuals) over the last year depicted in the chart below. If you want to know exactly who sold, for how much, and when, simply click on the graph below!
