What Does The Institutional Ownership Tell Us About Amkor Technology?

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.

Amkor Technology 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. 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 Amkor Technology's earnings history below. Of course, the future is what really matters.

We note that hedge funds don't have a meaningful investment in Amkor Technology. Sujochil, LP is currently the company's largest shareholder with 7.9% of shares outstanding.

Susan Kim, who is the second-largest shareholder, also happens to hold the title of Senior Key Executive.

We did some more digging and found that 9 of the top shareholders account for roughly 52% of the register, implying that along with larger shareholders, there are a few smaller shareholders, thereby balancing out each others interests somewhat.
