| About Arch Capital Group Ltd |
| Arch Capital Group Ltd. is a Bermuda-based company, which provides insurance, reinsurance and mortgage insurance through its subsidiaries. The insurance segment consists of the Co.'s insurance underwriting units, which offer specialty product lines, including construction and national accounts; excess and surplus casualty; professional lines; programs; property, energy, marine and aviation; travel, accident and health; warranty and lenders solutions, and others (consisting of alternative markets, excess workers' compensation and surety business). We show 65 historical shares outstanding datapoints in our ACGL shares outstanding history coverage, used to compute ACGL market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing ACGL market cap history over the course of time is important for investors interested in comparing ACGL'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 ACGL versus a peer is one thing; comparing ACGL 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 ACGL can fluctuate over the course of history. With this page we aim to empower investors researching ACGL by allowing them to research the ACGL market cap history. |
