The Problem with Sentiment Analysis
Most text analysis tools measure sentiment — whether language is positive or negative. This works for tweets and reviews. It fails for SEC filings.
Why? Because SEC filings are written by lawyers. They're always cautious. They're always full of risk factors. Every 10-K sounds negative if you just count warning words.
