Assume you've seen the "stop sign" for SIGO (otcmarkets.com).
That discourages most "serious investors". Mostly traders, speculators, and flippers are interested in these type of SEC-delinquent stocks. I like to trade and flip sometimes, which is why I have continued to follow this stock for the past year.
If SIGO does go on a run, I hope to hop on the train for a brief ride :)
