Here's my take on the situation. Screened about 180/300 stocks until now. About half of them failed the test and I would consider them "high risk" or "extreme risk". That doesn't mean they were blatant frauds, but as several criteria were missed (earnings quality, dilution, management continuity, ownership, auditors, backing, history, underwriters, etc) you should be prepared for (very) unpleasant surprises (see WATG tonight) unless you have done your homework.
Here are the names that came out green with my system. It is meant to be a starting point for further due diligence, not the ultimate truth. Only five RTO stocks made this list so far. Discussion welcome. (The list is sorted from highest safety to lowest)
