If you want to know who really controls ACM Research, Inc. (NASDAQ:ACMR), then you'll have to look at the makeup of its share registry. And the group that holds the biggest piece of the pie are institutions with 55% ownership. In other words, the group stands to gain the most (or lose the most) from their investment into the company.

Let's take a closer look to see what the different types of shareholders can tell us about ACM Research.

What Does The Institutional Ownership Tell Us About ACM Research?

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 ACM Research. This implies the analysts working for those institutions have looked at the stock and they like it. But just like anyone else, they could be wrong. 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 ACM Research's historic earnings and revenue below, but keep in mind there's always more to the story.
