What Does The Institutional Ownership Tell Us About Johnson Matthey?

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.

We can see that Johnson Matthey does have institutional investors; and they hold a good portion of the company's stock. 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. If multiple institutions change their view on a stock at the same time, you could see the share price drop fast. It's therefore worth looking at Johnson Matthey's earnings history below. Of course, the future is what really matters.

Institutional investors own over 50% of the company, so together than can probably strongly influence board decisions. We note that hedge funds don't have a meaningful investment in Johnson Matthey. Our data shows that RWC Partners Limited is the largest shareholder with 9.4% of shares outstanding. For context, the second largest shareholder holds about 5.8% of the shares outstanding, followed by an ownership of 5.0% by the third-largest shareholder.

A closer look at our ownership figures suggests that the top 13 shareholders have a combined ownership of 50% implying that no single shareholder has a majority.

While it makes sense to study institutional ownership data for a company, it also makes sense to study analyst sentiments to know which way the wind is blowing. There are plenty of analysts covering the stock, so it might be worth seeing what they are forecasting, too.

Insider Ownership Of Johnson Matthey

While the precise definition of an insider can be subjective, almost everyone considers board members to be insiders. Management ultimately answers to the board. However, it is not uncommon for managers to be executive board members, especially if they are a founder or the CEO.

Most consider insider ownership a positive because it can indicate the board is well aligned with other shareholders. However, on some occasions too much power is concentrated within this group.

Our most recent data indicates that insiders own less than 1% of Johnson Matthey Plc. Keep in mind that it's a big company, and the insiders own UK£4.5m worth of shares. The absolute value might be more important than the proportional share. Arguably, recent buying and selling is just as important to consider.
