What Does The Institutional Ownership Tell Us About Marathon Petroleum?

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.

Marathon Petroleum 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. 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 Marathon Petroleum's historic earnings and revenue below, but keep in mind there's always more to the story.

Since institutional investors own more than half the issued stock, the board will likely have to pay attention to their preferences. We note that hedge funds don't have a meaningful investment in Marathon Petroleum. Looking at our data, we can see that the largest shareholder is The Vanguard Group, Inc. with 9.9% of shares outstanding. For context, the second largest shareholder holds about 8.6% of the shares outstanding, followed by an ownership of 6.9% by the third-largest shareholder.

On studying our ownership data, we found that 25 of the top shareholders collectively own less than 50% of the share register, implying that no single individual has a majority interest.

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 Marathon Petroleum

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.

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 data suggests that insiders own under 1% of Marathon Petroleum Corporation in their own names. Being so large, we would not expect insiders to own a large proportion of the stock. Collectively, they own US$82m of stock. It is good to see board members owning shares, but it might be worth checking if those insiders have been buying.

General Public Ownership

With a 22% ownership, the general public, mostly comprising of individual investors, have some degree of sway over Marathon Petroleum. This size of ownership, while considerable, may not be enough to change company policy if the decision is not in sync with other large shareholders.
