On small cap biofuel companies

Concerning some biofuel companies, John Udovich writes

Small cap biofuel or synthetic fuel stocks Gevo, Inc (GEVO), KiOR Inc (KIOR), Solazyme Inc (SZYM) and Syntroleum Corp (SYNM) have been seeing plenty of trading action in recent days, but their financials and long term performance is not very inspiring.

Udovich did not get into the patent issues with Gevo.
