What Does The Institutional Ownership Tell Us About Costco Wholesale?

Institutions typically measure themselves against a benchmark when reporting to their own investors, so they often become more enthusiastic about a stock once it's included in a major index. We would expect most companies to have some institutions on the register, especially if they are growing.

Costco Wholesale already has institutions on the share registry. Indeed, they own a respectable stake in the company. This can indicate that the company has a certain degree of credibility in the investment community. However, it is best to be wary of relying on the supposed validation that comes with institutional investors. They too, get it wrong sometimes. It is not uncommon to see a big share price drop if two large institutional investors try to sell out of a stock at the same time. So it is worth checking the past earnings trajectory of Costco Wholesale, (below). Of course, keep in mind that there are other factors to consider, too.

Institutional investors own over 50% of the company, so together than can probably strongly influence board decisions. Costco Wholesale is not owned by hedge funds. The Vanguard Group, Inc. is currently the company's largest shareholder with 8.8% of shares outstanding. Meanwhile, the second and third largest shareholders, hold 6.8% and 4.2%, of the shares outstanding, respectively.

Our studies suggest that the top 25 shareholders collectively control less than half of the company's shares, meaning that the company's shares are widely disseminated and there is no dominant shareholder.

Insider Ownership Of Costco Wholesale

The definition of an insider can differ slightly between different countries, but members of the board of directors always count. The company management answer to the board and the latter should represent the interests of shareholders. Notably, sometimes top-level managers are on the board themselves.

Insider ownership is positive when it signals leadership are thinking like the true owners of the company. However, high insider ownership can also give immense power to a small group within the company. This can be negative in some circumstances.

Our data suggests that insiders own under 1% of Costco Wholesale Corporation in their own names. It is a very large company, so it would be surprising to see insiders own a large proportion of the company. Though their holding amounts to less than 1%, we can see that board members collectively own US$532m worth of shares (at current prices). It is good to see board members owning shares, but it might be worth checking if those insiders have been buying.
