| About MGIC Investment Corp. (WI) |
| MGIC Investment Corporation is a holding company. Co., through its wholly owned subsidiaries, provides private mortgage insurance, other mortgage credit risk management solutions, and ancillary services. Co.'s mortgage insurance product offers Primary Insurance and Pool and Other Insurance. Primary insurance provides mortgage default protection on individual loans and covers a percentage of the unpaid loan principal, delinquent interest and certain expenses associated with the default and subsequent foreclosure on the mortgage or sale of the underlying property. Pool insurance is generally used as an additional credit enhancement for certain secondary market mortgage transactions. We show 67 historical shares outstanding datapoints in our MTG shares outstanding history coverage, used to compute MTG market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing MTG market cap history over the course of time is important for investors interested in comparing MTG'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 MTG versus a peer is one thing; comparing MTG 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 MTG can fluctuate over the course of history. With this page we aim to empower investors researching MTG by allowing them to research the MTG market cap history. |
