I built Portfolio Backtest because I wanted an easy way to backtest hypothetical portfolios.

Alternatives required you to fill out long complicated forms to construct the backtest but I wanted something where you could just describe what you wanted in plain english.

Once created I wanted it to be able to track CAGR, portfolio value over, returns by year, drawdowns and a range of other metrics.

Portfolio Backtest features and specs

  • Easy Portfolio Backtesting
    Portfolio Backtest provides a straightforward interface for testing historical performance of investment portfolios, making it accessible to both beginner and intermediate investors who want to evaluate asset allocation strategies.
  • Multiple Asset Support
    The platform supports backtesting across a variety of asset classes including stocks, ETFs, and mutual funds, allowing users to construct diversified portfolios and analyze their historical behavior.
  • Visual Performance Charts
    The tool provides clear visual charts and graphs showing portfolio growth, drawdowns, and other performance metrics over time, making it easy to compare different allocation strategies at a glance.
  • Free to Use
    Portfolio Backtest offers free access to its core backtesting features, which lowers the barrier to entry for individual investors who want to test strategies without committing to expensive subscription-based tools.
  • Portfolio Comparison
    Users can compare multiple portfolio configurations side by side, enabling them to evaluate the impact of different asset allocations and rebalancing strategies on risk-adjusted returns.

Possible disadvantages of Portfolio Backtest

  • Limited Historical Data
    The platform may have limited historical data depth compared to more premium backtesting tools, which can restrict the ability to test strategies over very long time horizons or during specific market events.
  • Basic Analytics
    Compared to professional-grade tools like Portfolio Visualizer or QuantConnect, the analytics and risk metrics available on Portfolio Backtest can be relatively basic, lacking advanced measures such as factor exposure analysis or Monte Carlo simulations.
  • Limited Customization Options
    The tool may not offer extensive customization for rebalancing frequencies, tax-loss harvesting simulations, or custom benchmarks, which limits its usefulness for more sophisticated portfolio strategies.
  • Smaller User Community
    Portfolio Backtest has a smaller user base and community compared to more established platforms, meaning there are fewer tutorials, forums, and shared strategies available for new users seeking guidance.
  • Survivorship Bias Risk
    Like many free backtesting tools, Portfolio Backtest may be subject to survivorship bias in its asset database, as delisted or failed securities might not be included, potentially leading to overly optimistic backtest results.

SimpleX features and specs

  • Simple and intuitive interface
    SimpleX provides a clean, straightforward interface for decision-making that doesn't overwhelm users with unnecessary complexity, making it accessible to people without technical expertise.
  • Structured decision framework
    The tool helps users organize their thinking by providing a structured approach to evaluating options against multiple criteria, reducing the likelihood of overlooking important factors.
  • Free to use
    SimpleX appears to be a free web-based tool, making it accessible to anyone who needs help making decisions without requiring a financial commitment.
  • Web-based accessibility
    As a browser-based application, SimpleX requires no software installation and can be accessed from any device with an internet connection, making it convenient for quick decision-making on the go.
  • Visual comparison of options
    The tool provides a visual representation of how different options compare against each other across various criteria, making it easier to see which option comes out ahead overall.

Possible disadvantages of SimpleX

  • Limited advanced features
    SimpleX focuses on simplicity, which means it may lack more sophisticated decision analysis features such as sensitivity analysis, probability weighting, or Monte Carlo simulations that more advanced tools offer.
  • Low visibility and community
    SimpleX is a relatively niche tool with a small user base, which means limited community support, fewer tutorials, and less peer feedback compared to more established decision-making platforms.
  • Potential oversimplification
    For complex decisions involving many interdependent variables, the simplified framework may not adequately capture nuances, dependencies, or non-linear relationships between criteria.
  • Limited collaboration features
    The tool may lack robust collaboration capabilities for team-based decision-making, such as real-time co-editing, role-based access, or voting mechanisms for group consensus.
  • No offline functionality
    Being a web-based tool, SimpleX requires an internet connection to function, which can be a limitation in situations where connectivity is unreliable or unavailable.
