Sharpe: Portfolio Analytics for DEGIRO

Upgrade DEGIRO with a secure, local dashboard offering advanced return tracking, risk grading, and deep insights.

Sharpe transforms your DEGIRO brokerage into a professional-grade analytics platform. Every calculation runs locally in your browser — your portfolio data never leaves your device. Whether you're a passive investor or an active trader optimising your strategy, Sharpe gives you the tools to understand your portfolio at a deeper level than DEGIRO's built-in interface allows. — WHAT'S NEW IN v1.6 — Portfolio Pulse: A plain-language read on your portfolio. Sharpe highlights what actually matters — creeping concentration, what currency moves cost you, whether your risk-adjusted returns are improving, how your fees compare — each with a link to the chart that proves it. No jargon, no interpretation required. Redesigned Positions Table: See position weight as a bar, a 30-day sparkline per holding, and P&L at a glance. Click any row to expand its details in place — average cost, daily P&L, return contribution, volatility and price chart — instead of hunting for a chart below the table. Filter instantly by name, ISIN or currency (press "/"). Allocation Drill-Down: Replaces the pie chart with a ranked breakdown that shows every holding, no clipped legend. Click any region, currency or asset class to see the holdings inside it. A concentration warning appears when your top 3 holdings dominate the portfolio. Dividends Tab: Track your income over time with a 12-month monthly chart, total received, and yield on cost. Includes estimated upcoming payments projected from each holding's own payment cadence (estimates based on your history, not issuer announcements). Smarter Syncing: Refreshing no longer blanks the screen — your data stays on screen while fresh figures load. Clearer messaging when data is stale, with a single button to fix it. Fixes & Polish: Fixed the S&P 500 comparison silently disappearing after a failed data fetch. Fixed inconsistent number formatting in chart tooltips. Fixed the empty state for brand-new accounts. Faster loads (first sync no longer fetches twice), unified tooltips that no longer clip at card edges, and a lighter, tidier codebase throughout. SHARPE PRO — NEW IN v1.6 Per-Holding Dividend Breakdown: Payments, total received, trailing-12-month income and yield on cost for every holding, with CSV export. — CORE FEATURES — True Time-Weighted Returns (TWR): Performance that strips out the distorting effect of your deposits and withdrawals, so you're measuring your decisions rather than your cash flow. Benchmark Overlays: Compare your portfolio against the S&P 500, Euro Stoxx 50 and Nasdaq 100 directly on the Performance chart — plus a day-by-day "vs S&P 500" comparison on recent activity. Drag-to-Zoom: Click and drag on the main chart to zoom into any custom date range. Professional Metrics: Annualised return, Alpha, Beta, Max Drawdown and Sharpe Ratio, all computed from your own daily portfolio values. Full Cost Transparency: Total fees paid, split between trading commissions and FX conversion fees, plus the exact impact of exchange-rate movements on your non-EUR holdings. Realized P&L: Historical profit and loss from sold positions using FIFO cost-basis matching, including partially closed positions. Privacy Mode: One click blurs every figure on screen — safe for screenshots and shoulder-surfing. SHARPE PRO — FULL LIST Today Tab: Live trading-day dashboard with intraday P&L timeline, today's movers, contribution waterfall, and a portfolio heatmap grouped by asset class or geography. Watchlist: Track your DEGIRO favourites with a composite return chart, correlation to your portfolio per stock, SMA crossover momentum signals and side-by-side comparison stats. Tax Reporting: Country-specific tax summaries (NL, FR, DE, BE) with FIFO-matched realized gains per year. Export as CSV. Rate My Portfolio: A graded assessment of your portfolio against your own stated risk tolerance, goals and time horizon. Correlation Matrix: See which of your holdings actually move together, with weighted average correlation and principal-component analysis. Risk Analysis: Value at Risk plus historical and hypothetical stress-test scenarios. Stock Price Charts: Per-holding price history with your own buy and sell points marked. CSV Export: Available on every chart and table. — PRIVACY & SECURITY — 100% local: no servers, no accounts, no data collection.
