Chief Technology Officer Of Coherent Sold 48% Of Their Shares

We wouldn't blame Coherent Corp. (NYSE:COHR) shareholders if they were a little worried about the fact that Julie Eng, the Chief Technology Officer recently netted about US$647k selling shares at an average price of US$90.67. That's a big disposal, and it decreased their holding size by 48%, which is notable but not too bad.

The Last 12 Months Of Insider Transactions At Coherent

In fact, the recent sale by Julie Eng was the biggest sale of Coherent shares made by an insider individual in the last twelve months, according to our records. That means that even when the share price was below the current price of US$95.62, an insider wanted to cash in some shares. 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. However, while insider selling is sometimes discouraging, it's only a weak signal. This single sale was just 48% of Julie Eng's stake.

All up, insiders sold more shares in Coherent than they bought, over the last year. The average sell price was around US$88.75.
