Exercise 5.7. The goal of this project is to build a knowledge graph of headwinds and tailwinds facing a company as reported earnings calls transcripts. For this project, you can use any publicly available earnings calls transcripts. This project will give you hands-on experience with text processing, information extraction, and knowledge graph construction. Proceed in the following steps.

1. Select companies and time window
   • Choose a small number of well-known companies to focus on.
   • Select a suitable time window so that you can work with multiple transcripts for the same company across different quarters.
2. Identify financial headwinds and tailwinds
   • Process each transcript to extract factors that may positively (tailwinds) or negatively (headwinds) affect the company's stock performance.
   • Consider categorizing these factors (e.g., market trends, regulatory changes, supply chain issues) to make the database more informative.
3. Optional analysis
   • Even though this task is meant for future chapters, Once your database is populated, begin exploring patterns across companies and quarters, or visualizing the relationships and factors affecting stock performance.
