A detailed brief explaining which managers drove changes in a stock's institutional ownership, whether insider Form 4 activity corroborates the trend, and the specific SEC filing evidence supporting these findings.
The agent receives a stock ticker and calls the capital_change_brief tool. It analyzes the response to identify the largest disclosed changes in 13F positions and checks for qualifying Form 4 purchases or sales over the last 180 days. The agent must verify the outcome status (complete, partial, or uncertain), review the headline and counts, and cite the specific SEC evidence IDs and links provided in the response. It should also note any coverage limitations or quality artifacts that might affect the interpretation of the data.
