The ETF Builder & Backtest System enables users to construct a custom portfolio by selecting up to 10 different assets and assigning specific percentage weights to each. The script calculates a composite portfolio value by tracking the performance of each selected asset over a specified time range, normalizing the starting value to 100 for easy comparison.
As the portfolio progresses, the system automatically records each asset's starting price, continuously updates the asset prices, and computes overall portfolio returns. It generates a comprehensive performance table showing individual asset returns, percentage weights, and annualized returns, providing traders with a detailed view of their hypothetical portfolio's historical performance.
Why it may be useful
This tool empowers traders and investors to quickly assess potential portfolio compositions without complex spreadsheet calculations or external software. By allowing users to experiment with different asset combinations and weightings, the system provides valuable insights into potential risk and return profiles across various market conditions.
The ability to backtest and visualize portfolio performance helps investors make more informed decisions about asset allocation, understand how different assets interact, and develop more sophisticated investment strategies. It serves as an educational and analytical tool that bridges the gap between theoretical portfolio construction and practical performance evaluation.
When to explore it
The ETF Builder & Backtest System is most effective when investors want to explore historical performance of potential multi-asset portfolios before making actual investment decisions. It is particularly useful for long-term investors interested in understanding how different asset combinations might have performed over extended periods.
Traders and portfolio managers can leverage this tool to test hypothetical portfolio strategies, compare different asset weightings, and gain insights into potential portfolio diversification approaches. It is especially valuable for those looking to create balanced, multi-asset investment strategies that go beyond single-asset trading approaches.
