SIOR is an OTC Pink,, it is an awesome risk.
For an explanation of what the stop sign actually means, see below and make your own interpretation. My interpretation is that this is a risk worth taking.
OTC Pink No Information (with a STOP Sign)
Indicates companies that are not able or willing to provide disclosure to the public markets - either to a regulator, an exchange or OTC Markets Group. Companies in this category do not make Current Information available via OTC Markets Group's News Service, or if they do, the available information is older than six months. This category includes defunct companies that have ceased operations as well as 'dark' companies with questionable management and market disclosure practices. Publicly traded companies that are not willing to provide information to investors should be treated with suspicion and their securities should be considered highly risky.
