I personally rely on it for my own decisions, but like any tool, it's most effective when used as part of a broader analysis process. The system is great at rapidly surfacing the most significant changes in these massive documents and contextualizing them against historical patterns. That's incredibly valuable for making timely decisions, especially since the market often takes days or weeks to fully price in the implications of complex filing changes.
That said, the analysis code has built in multiple validation layers and error handling because filings are just one piece of the market puzzle. The code is designed to be conservative - it'll fail closed rather than make questionable assertions. But for what it's designed to do - deep analysis of filing changes and their implications - it's proven to be a reliable tool for actual decision-making.
probably worth capturing a few successful situations and documenting that in some marketing way.. also probably worth capturing a few Very Big Fails and making a ticket out of that internally, to improve the system. Seize the day!
This doesn't say anything. Exactly how much have you tested and what were the results?
