How do you follow market data as part of valuation?

To follow market data for valuation, I would first identify the relevant data sources such as Bloomberg, Reuters, or public APIs like Alpha Vantage and Yahoo Finance. I would set up automated data pulls using scheduled scripts or services (e.g., AWS Lambda with cron triggers) to fetch daily price, volume, and fundamental metrics. The data would be stored in a time‑series database or a relational table with proper indexing. I would then normalize the data (e.g., adjust for splits, dividends) and compute key valuation metrics such as P/E, EV/EBITDA, or discounted cash flow inputs. Regularly updating the dataset ensures that valuation models reflect current market conditions. Additionally, I would monitor data quality and handle missing values or outliers to maintain model integrity.
