Insiders At Southern Sold US$15m In Stock, Alluding To Potential Weakness

Simply Wall St

Many The Southern Company (NYSE:SO) insiders ditched their stock over the past year, which may be of interest to the company's shareholders. When evaluating insider transactions, knowing whether insiders are buying is usually more beneficial than knowing whether they are selling, as the latter can be open to many interpretations. However, when multiple insiders sell stock over a specific duration, shareholders should take notice as that could possibly be a red flag.

While we would never suggest that investors should base their decisions solely on what the directors of a company have been doing, we would consider it foolish to ignore insider transactions altogether.

Southern Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider sale was by the Chairman, Kimberly Greene, for US$3.0m worth of shares, at about US$93.12 per share. So what is clear is that an insider saw fit to sell at around the current price of US$92.33. While insider selling is a negative, to us, it is more negative if the shares are sold at a lower price. Given that the sale took place at around current prices, it makes us a little cautious but is hardly a major concern.
