| About Affiliated Managers Group Inc. |
| Affiliated Managers Group, Inc. is a global independent investment management company. Co. is focused on investing in a range of partner-owned investment firms, known as Affiliates. Its Affiliates provide a diverse range of differentiated investment strategies designed to assist institutional and wealth clients worldwide in achieving their investment objectives. Its Affiliates also provide investment management and customized investment counseling and fiduciary services to high-net worth individuals and families and institutional clients. We show 71 historical shares outstanding datapoints in our AMG shares outstanding history coverage, used to compute AMG market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing AMG market cap history over the course of time is important for investors interested in comparing AMG's market cap history versus its peers. Many "beginner" or "novice" investors will look at one stock trading at a price of $10 per share and another trading at a price of $20 per share and think the latter company is worth twice as much. Of course, that is a completely meaningless comparison without also knowing how many shares outstanding there are for each of the two companies, and then calculating their respective market caps. Comparing the share price of AMG versus a peer is one thing; comparing AMG market cap versus a peer is a completely different story. Furthermore, via fluctuation both in per-share price and in the number of shares outstanding (via issuance of new shares over time, the repurchase of existing shares), the market cap for a company like AMG can fluctuate over the course of history. With this page we aim to empower investors researching AMG by allowing them to research the AMG market cap history. |
