I built PennyTune because the real risks in a micro-cap, dilution, going-concern doubt, a delisting notice buried in an 8-K, are all sitting in the SEC filings, but most screeners just sort by price and volume and never open a single filing.

The CLI does the reading for you. You point it at a US-listed ticker and it computes forensic risk signals from the company's public SEC filings: financial-distress and accounting-quality scores, dilution, insider activity, 8-K events, and delisting and trading-suspension risk. For event-driven red flags it names the 8-K item behind them.

Public SEC EDGAR data only, no API key, no account. Runs on Linux, macOS, and Windows.

It surfaces evidence for your own due diligence, not buy/sell advice.

365 tests across 12 OS/Python combinations. MIT licensed, open source.

Would love to hear what you think.
