# Track Portfolio Performance

Keeping tabs on a portfolio spread across multiple stocks requires checking each position individually -- or paying for a dedicated portfolio tracker. For quick daily checks, neither option is ideal. You want to know your total portfolio value, which positions are up or down, and how the overall portfolio changed today.

By providing your holdings list to the agent, it can fetch real-time quotes for every position, calculate individual and total values, and show you daily gains and losses. The conversation format means you can ask follow-up questions like "which position dragged the portfolio down today?" or "what percentage of my portfolio is in tech?"

This approach works for individual investors managing personal portfolios, financial advisors doing quick client check-ins, and anyone who wants a portfolio snapshot without logging into a brokerage. The agent handles the math so you get actionable insights, not raw numbers.
