A penny stock can file an 8-K disclosing a continued-listing deficiency, and the next morning most retail screeners will still show it as a green "buy." The warning was right there in the filing. The screener never read it.
That gap is the whole reason this tool exists.
Most penny stock and micro-cap screeners sort by price, volume, and a handful of ratios. They don't open the filings. But for a small, thinly covered company, the things that actually matter, dilution, going-concern doubt, a delisting notice, a restatement, are disclosed in SEC filings long before they show up in the price.
