Over the past year, many Costco Wholesale Corporation (NASDAQ:COST) 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, 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, logic dictates you should pay some attention to whether insiders are buying or selling shares.

The Last 12 Months Of Insider Transactions At Costco Wholesale

Over the last year, we can see that the biggest insider sale was by the insider, James Klauer, for US$3.9m worth of shares, at about US$981 per share. So it's clear an insider wanted to take some cash off the table, even below the current price of US$1,026. When an insider sells below the current price, it suggests that they considered that lower price to be fair. That makes us wonder what they think of the (higher) recent 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 8.3% of James Klauer's holding.

In the last year Costco Wholesale insiders didn't buy any company stock. 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!
