| About Digital Realty Trust Inc |
| Digital Realty Trust, Inc. operates as a real estate investment trust. Co. is engaged in the business of owning, acquiring, developing, and operating data centers. It is a global provider of data center, colocation, and interconnection solutions for customers across a variety of industry verticals ranging from cloud and information technology services, social networking and communications to financial services, manufacturing, energy, healthcare, and consumer products. We show 62 historical shares outstanding datapoints in our DLR shares outstanding history coverage, used to compute DLR market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing DLR market cap history over the course of time is important for investors interested in comparing DLR'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 DLR versus a peer is one thing; comparing DLR 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 DLR can fluctuate over the course of history. With this page we aim to empower investors researching DLR by allowing them to research the DLR market cap history. |
