Analyzes stock liquidity through bid-ask spreads, volume profiles, order book depth, market impact estimates, and turnover ratios using Yahoo Finance data. Built around six sub-skills that route based on your question: a full dashboard view, spread analysis, volume breakdowns, order book inspection, market impact modeling for large orders, and turnover calculations. Uses the Amihud illiquidity ratio and square-root impact models, which is more rigorous than just eyeballing volume. Helpful when you're sizing positions in less liquid names or estimating real execution costs beyond the quoted price. The liquidity grading rubric is sensible. Worth noting it's educational only and relies on yfinance, which can be spotty for real-time quotes.
