| About Realty Income Corp |
| Realty Income Corporation is a real estate investment trust. Co. is engaged in acquiring and managing freestanding commercial properties that generate rental revenue under long-term net lease agreements with its commercial clients. It is engaged in a single business activity, which is the leasing of property to clients, generally on a net basis. That business activity spans various geographic boundaries and includes property types and clients engaged in various industries. We show 65 historical shares outstanding datapoints in our O shares outstanding history coverage, used to compute O market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing O market cap history over the course of time is important for investors interested in comparing O'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 O versus a peer is one thing; comparing O 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 O can fluctuate over the course of history. With this page we aim to empower investors researching O by allowing them to research the O market cap history. |
