Portfolio Tracker
Monitor your stock portfolio with live prices, daily changes, total value, and overall P&L. No signup required — all data stays in your browser.
Add holdings with cost basis, update prices, and monitor total value and P&L. Privacy-first: everything stays in your browser, with CSV export when you want a snapshot.
Free portfolio tracker that stays on your device
Most portfolio apps want an account, a feed of ads, or a path to sell you advice. This free portfolio tracker is different: add tickers, shares, and cost basis; update prices; watch total value and P&L — all stored in your browser. We never see what you own.
What you can track
- Positions: Symbol, shares, cost basis, and current price per holding.
- P&L: Dollar and percent gain/loss per position and across the whole portfolio.
- Totals: Market value, invested capital, and overall return at a glance.
- CSV export: Download a snapshot for records or spreadsheets.
How to use this stock portfolio tracker
- Enter symbol, shares, and average cost (cost basis).
- Click Add to save the position locally.
- Refresh prices using live stock lookup or your broker app.
- Review portfolio totals and per-stock performance.
- Export CSV before clearing browser data or switching devices.
Portfolio tracking tips
Cost basis matters for taxes and honest performance. Include all lots if you averaged down. Separately, practice trading ideas in the stock market simulator so paper experiments don’t clutter your real holdings list. Measure multi-year results with the investment return calculator.
Why privacy-first tracking?
Your holdings are sensitive. Cloud trackers can leak data in breaches, upsell products, or profile your wealth. Local storage isn’t perfect (device loss, browser clears), but it’s a strong default for simple monitoring — especially if you already have a brokerage as the system of record.
