AGNC Investment Corp. is an internally managed real estate investment trust (REIT) that provides private capital to the U.S. housing market, enhancing liquidity in residential mortgage markets and facilitating home ownership. Co. primarily invests in Agency residential mortgage-backed securities (Agency RMBS) on a leveraged basis. These investments include residential mortgage pass-through securities and collateralized mortgage obligations, with principal and interest payments guaranteed by U.S. Government-sponsored enterprises like Fannie Mae and Freddie Mac, or by a U.S. Government agency like Ginnie Mae. AGNC may also invest in other housing, mortgage, or real estate-related assets. We show 64 historical shares outstanding datapoints in our AGNC shares outstanding history coverage, used to compute AGNC market cap on those dates.

Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing AGNC market cap history over the course of time is important for investors interested in comparing AGNC'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 AGNC versus a peer is one thing; comparing AGNC 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 AGNC can fluctuate over the course of history. With this page we aim to empower investors researching AGNC by allowing them to research the AGNC market cap history.
