Over the past year, many Aflac Incorporated (NYSE:AFL) insiders sold a significant stake in the company which may have piqued investors' interest. Knowing whether insiders are buying is usually more helpful when evaluating insider transactions, as insider selling can have various explanations. However, if numerous insiders are selling, shareholders should investigate more.

Although we don't think shareholders should simply follow insider transactions, we do think it is perfectly logical to keep tabs on what insiders are doing.

Aflac Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider sale was by the Executive Vice President, Frederick John Crawford, for US$8.1m worth of shares, at about US$81.37 per share. So it's clear an insider wanted to take some cash off the table, even below the current price of US$83.61. 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 30% of Frederick John Crawford's holding.

In the last twelve months insiders purchased 2.50k shares for US$191k. But they sold 179.43k shares for US$15m. Over the last year we saw more insider selling of Aflac shares, than buying.

Does Aflac Boast High Insider Ownership?

I like to look at how many shares insiders own in a company, to help inform my view of how aligned they are with insiders. I reckon it's a good sign if insiders own a significant number of shares in the company. It's great to see that Aflac insiders own 0.8% of the company, worth about US$404m. This kind of significant ownership by insiders does generally increase the chance that the company is run in the interest of all shareholders.
