Understanding the changing numbers of CMS shares outstanding — and comprehending the concept of differing number of shares outstanding in general comparing companies like CMS versus peers — is critical for investors. 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. Furthermore, via issuance of new shares over time, or the repurchase of existing shares, the number of shares outstanding can fluctuate over the course of history.
