This article explains how to compare the previous and current editions of an annual securities report and have AI read only the “changes,” such as additions, deletions and rewording, to identify shifts in meaning more quickly. Focusing on changes helps investors concentrate on developments relevant to investment decisions.
Annual securities reports contain a large volume of information, making it inefficient to read the entire document from the beginning. The author argues that readers should use the changes between the previous and current editions to interpret shifts in a company’s perceptions and priorities. Focusing on changes can be made more effective with the use of AI.
Changes include not only newly added text, but also deletions, rewording, numerical changes and changes in order. These may indicate the company’s level of concern about risks or the emphasis it places on its growth strategy. The article explains that it is important to focus on changes in meaning, not merely differences in character count.
As a practical method, the article describes how to extract comparable passages from the previous and current editions, remove noise such as different line breaks and variations in notation, and format the material for submission to AI. It proposes using prompts that require AI to distinguish between additions, deletions and rewording, and to assess their meaning while showing the original text.
The ultimate objective is not to entrust decisions to AI, but to narrow down the areas that require human judgement. The approach is to use changes to identify issues the company prioritised during the year and signs of a shift in direction, thereby strengthening the information supporting investment decisions.
