About
Portfolio Performance is an open source tool designed to calculate the overall performance of an investment portfolio across all accounts. Users can record the full history of transactions, including purchases, sales, taxes, and fees. It allows updating historical quotes from various sources such as Yahoo Finance, Finnhub.io, Quandl, or AlphaVantage, and also supports scraping quotes from HTML pages or JSON documents. All data is stored in XML for further processing and can be exported as CSV or JSON. Portfolio Performance enables users to rebalance their investment portfolios based on a freely defined asset allocation and supports foreign currency accounts using exchange rates published by the European Central Bank (ECB). It supports importing data from CSV files and PDF documents, and provides detailed reports including statements of assets and performance calculations.

About
Redstone is a web-based portfolio analytics and investment research product for self-directed investors, analysts and people learning portfolio theory. It provides return and risk measures for about 2,900 U.S. stocks and 1,200 ETFs, including Sharpe ratio, maximum drawdown, volatility and correlations. Users can screen securities, compare tickers, build and share portfolios, review allocations, and backtest portfolios against historical data and benchmarks. Public ticker data and comparisons are available without an account. Free and paid plans add portfolio capacity, optimization tools, private portfolios and watchlists. A free, read-only Model Context Protocol (MCP) server lets compatible AI assistants retrieve metrics, screen or compare securities, look up portfolios and run backtests. Data refreshes daily after the U.S. market close. Redstone is for informational and educational use, not investment advice.
