Compare funds on risk and cost metrics with charts
A commenter has ChatGPT compare funds on max drawdown, Sharpe ratio, expense ratio, tax drag and overlap, then generate a chart. · Apr 1, 2026
- What They Did
- One commenter said they ask ChatGPT to compare a group of funds across max drawdown, Sharpe ratio, expense ratio, tax drag, three-year return, and holdings overlap, then have it assemble the results into a chart. They used it mainly for comparisons that normally require pulling data from several separate tools such as ETF overlap tools, Portfolio Visualizer, and Morningstar, and relied on their own judgment to catch mistakes.
- How It Went
- The payoff was speed and convenience in combining metrics from multiple sources into one view. The limitation was accuracy: the commenter said it was not entirely accurate and only worked because they could recognize flaws.
- Worth Knowing
- The main catch was verification: the commenter explicitly said the output was not fully accurate, so this only worked for someone able to spot errors themselves.
Try it yourself with ChatGPT
Compare these funds: [list of tickers]. For each, give max drawdown, Sharpe ratio, expense ratio, estimated tax drag, and the holdings overlap between each pair, and show your data sources and time period. Then make one chart that visualizes the risk versus cost tradeoff, and finish with a short summary table ranking them for [my goal, e.g. long-term taxable account].
