Pyro is a growth stock on the cusp of commercializing its many applications.
Investors are free to agree or disagree with this statement. If they agree, they buy some shares. If they don't agree with this statement, they don't buy.
What investors in Pyro don't do at this time is consider book value of assets. Book value is an accounting term with a very specific definition. Book value has nothing to do with fair market value.
In relation to important financial information for Pyro I think you need to focus on debt, receivables, short term liabilities including payroll. But most importantly, you must seriously consider potential. In doing so you analyze the technology, its relevance and the pipeline of deals and potential deals just for starters. If your interest is piqued you then do more analysis, including barriers to entry and competition, macro issues.
For me, the above information is part of the due diligence. Lots more to consider.
Based on all of this work, I decided Pyro is worth risking some money.
What I didn't do is focus in any way on Pyro's balance sheet because it doesn't come close to telling us the complete story of Pyro.
