Thanks for assembling this list. I always keep 3 or 4 SEC reporting shells in my portfolio for when they pop. Most recent one was RTRO a year or so ago. Still have SDON. I used to follow shellstock review.com, but that site has not been updated in 3 years.
What screener did you use? I haven't done much screening last couple of years and can't seem to find any to screen on o/s. Maybe I'm not looking at the right ones.
Also, is it possible to put your table in a format that can be imported into Excel for those of us who want to play with/expand it with other stocks and columns? TIA.
