ClearSign Technologies Corporation designs and develops products and technologies for the purpose of improving key performance characteristics of industrial and commercial systems, including operational performance, energy efficiency, emission reduction, safety, and overall cost-effectiveness. We show 60 historical shares outstanding datapoints in our CLIR shares outstanding history coverage, used to compute CLIR market cap on those dates.

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