What Does The Institutional Ownership Tell Us About Comcast?

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.

Comcast already has institutions on the share registry. Indeed, they own a respectable stake in the company. This suggests some credibility amongst professional investors. But we can't rely on that fact alone since institutions make bad investments sometimes, just like everyone does. 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 Comcast, (below). Of course, keep in mind that there are other factors to consider, too.

Investors should note that institutions actually own more than half the company, so they can collectively wield significant power. Comcast is not owned by hedge funds. The company's largest shareholder is The Vanguard Group, Inc., with ownership of 9.8%. With 8.0% and 5.8% of the shares outstanding respectively, BlackRock, Inc. and Capital Research and Management Company are the second and third largest shareholders. Furthermore, CEO Brian Roberts is the owner of 0.9% of the company's shares.

After doing some more digging, we found that the top 20 have the combined ownership of 50% in the company, suggesting that no single shareholder has significant control over the company.

While studying institutional ownership for a company can add value to your research, it is also a good practice to research analyst recommendations to get a deeper understand of a stock's expected performance. There are a reasonable number of analysts covering the stock, so it might be useful to find out their aggregate view on the future.

Insider Ownership Of Comcast

The definition of company insiders can be subjective and does vary between jurisdictions. Our data reflects individual insiders, capturing board members at the very least. 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 Comcast 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$1.2b worth of shares (at current prices). In this sort of situation, it can be more interesting to see if those insiders have been buying or selling.

General Public Ownership

With a 13% ownership, the general public, mostly comprising of individual investors, have some degree of sway over Comcast. While this size of ownership may not be enough to sway a policy decision in their favour, they can still make a collective impact on company policies.
