We show 69 historical shares outstanding datapoints in our FTNT shares outstanding history coverage, used to compute FTNT market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing FTNT market cap history over the course of time is important for investors interested in comparing FTNT'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 FTNT versus a peer is one thing; comparing FTNT 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 FTNT can fluctuate over the course of history. With this page we aim to empower investors researching FTNT by allowing them to research the FTNT market cap history. |
