If you want to know who really controls Comcast Corporation (NASDAQ:CMCSA), then you'll have to look at the makeup of its share registry. We can see that institutions own the lion's share in the company with 87% ownership. Put another way, the group faces the maximum upside potential (or downside risk).
Because institutional owners have a huge pool of resources and liquidity, their investing decisions tend to carry a great deal of weight, especially with individual investors. As a result, a sizeable amount of institutional money invested in a firm is generally viewed as a positive attribute.
Let's delve deeper into each type of owner of Comcast, beginning with the chart below.
What Does The Institutional Ownership Tell Us About Comcast?
Institutional investors commonly compare their own returns to the returns of a commonly followed index. So they generally do consider buying larger companies that are included in the relevant benchmark index.
As you can see, institutional investors have a fair amount of stake in Comcast. 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. When multiple institutions own a stock, there's always a risk that they are in a 'crowded trade'. When such a trade goes wrong, multiple parties may compete to sell stock fast. This risk is higher in a company without a history of growth. You can see Comcast's historic earnings and revenue below, but keep in mind there's always more to the story.

Investors should note that institutions actually own more than half the company, so they can collectively wield significant power. Hedge funds don't have many shares in Comcast. The company's largest shareholder is The Vanguard Group, Inc., with ownership of 9.9%. For context, the second largest shareholder holds about 8.1% of the shares outstanding, followed by an ownership of 5.9% by the third-largest shareholder. In addition, we found that Brian Roberts, the CEO has 0.9% of the shares allocated to their name.
After doing some more digging, we found that the top 20 have the combined ownership of 51% in the company, suggesting that no single shareholder has significant control over the company.
Researching institutional ownership is a good way to gauge and filter a stock's expected performance. The same can be achieved by studying analyst sentiments. 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. Company management run the business, but the CEO will answer to the board, even if he or she is a member of it.
I generally consider insider ownership to be a good thing. However, on some occasions it makes it more difficult for other shareholders to hold the board accountable for decisions.
Our information suggests that Comcast Corporation insiders own under 1% of the company. 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
The general public-- including retail investors -- own 12% stake in the company, and hence can't easily be ignored. 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.
Next Steps:
While it is well worth considering the different groups that own a company, there are other factors that are even more important. Like risks, for instance. Every company has them, and we've spotted 2 warning signs for Comcast (of which 1 shouldn't be ignored!) you should know about.
