Over the past year, many Duke Energy Corporation (NYSE:DUK) 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, logic dictates you should pay some attention to whether insiders are buying or selling shares.

Duke Energy Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider sale was by the Chairman & CEO, Lynn Good, for US$1.5m worth of shares, at about US$103 per share. So it's clear an insider wanted to take some cash off the table, even below the current price of US$117. 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. Please do note, however, that sellers may have a variety of reasons for selling, so we don't know for sure what they think of the stock price. We note that the biggest single sale was only 2.9% of Lynn Good's holding.
