EPS and Target P/E are pre-filled from Yahoo Finance fundamentals (trailing-twelve-month EPS and current trailing P/E); Annual dividend / yield likewise. Edit any of them to model your own assumptions. Then: Fair value = EPS × target P/E (or dividend ÷ target yield) · Buy below = fair × (1 − margin of safety) · Sell above = fair × (1 + take-profit premium).

Methodology

Geometric Brownian Motion (GBM)

Each asset class is projected independently using a simplified GBM model. The mean path is deterministic compound interest; the confidence bands scale with time:

mean(t)  = S₀ × (1 + r)^t
upper(t) = mean(t) × e^(+z × σ × √t)
lower(t) = mean(t) × e^(−z × σ × √t)

Asset	Volatility σ
Stocks / ETFs	16%
Bonds	6%
Cash	1%

Mortgage Amortization

The mortgage is reduced month-by-month using standard amortization:

Monthly interest  = balance × (annual_rate / 12)
Principal payment = monthly_payment − monthly_interest

Net Worth = total liquid assets (cash + stocks + bonds) − remaining mortgage balance at each year.

Data & sources

Prices, fundamentals and news come from Yahoo Finance (refreshed daily at 20:00 UTC; fundamentals/news are cached briefly).

Cost basis, gains and tax use your own transactions (FIFO). Tax is a Spanish IRPF savings-base estimate, not advice.

LLM/AI answers are generated from your data + cited news — informational, not financial advice.

What's New

Recent improvements to Portfolio Manager.

Late June – July 2026

AI Chat Agentic tool calling — the assistant can now call 15 portfolio tools mid-conversation (holdings, performance, tax, dividends, and more) instead of working from a static snapshot, across all four LLM providers (Anthropic, Gemini, OpenRouter, Ollama).
Import Generic CSV import for any broker not natively supported, with auto-detected delimiter, date style and decimal style. Import previews also gained editable, autocomplete-backed symbol search.
Tax Multi-currency tax report, estimate and optimizer now convert realised gains, dividends and interest at the historical FX rate on the transaction date, not today's rate — more accurate IRPF figures for foreign-currency holdings.
Dashboard On-demand price refresh — trigger a price update from the dashboard instead of waiting for the nightly job, with live running/status feedback.
Reliability Clearer error message when the backend is unreachable at login, plus assorted import and tax-report edge-case fixes.

June 2026

Assets Auto-fill tickers — one click resolves missing Yahoo Finance tickers for ISIN-keyed assets via the OpenFIGI API.
Analytics Correlation heatmap added to Risk & Diversification. Stress Test tab applies historical crash scenarios to your current holdings.
Analytics Broker Comparison tab shows value, P&L and holdings breakdown across all your brokers.
PWA Install Portfolio Manager on your home screen (Android / iOS). Push notifications for price alerts.

Early 2026

Net Worth New page: investments (auto) + off-brokerage cash, property, pension, mortgage, loans and fixed deposits → total net worth. Monthly cash flow tracker included.
Tax Per-lot FIFO tax report with CSV export, year-end tax optimizer (harvestable losses, Spain's 2-month wash-sale flag), and P2P/savings interest as a first-class transaction type.
Research Workbench with autocomplete, position panel (cost basis, P/L, sell calculator, avg-cost chart), Yahoo fundamentals, LLM web-search analysis, and downloadable Markdown reports.
AI Chat The assistant now reads your real portfolio (holdings, performance, history), renders Markdown, and works in dark mode.
Analytics Lazy-loaded tabs (Performance & Net Worth · Dividends · Gain/Loss · Tax · Risk · Fees); gain/loss leaderboard, dividend calendar, European benchmarks, Sharpe/Sortino/Calmar ratios.
UI Dark mode, grouped collapsible sidebar, settings modal, privacy blur mode, and Help / Glossary / Resources pages.
