Build a portfolio
Open Portfolios → Builder to create a portfolio from completed runs in your backtest library. The builder guides you through Portfolio setup, Configuration, and Review results.
Choose your strategies
- Enter a name that identifies the experiment.
- Choose Fixed weights or Inverse volatility as the allocation model. The allocation guide explains both.
- Select Choose backtests. Search by the beginning of a run or strategy name, select the finished runs you want, and choose Apply selection.
- Review each strategy's Observed coverage, then continue to Configuration.
You can select a single backtest. With fixed weights, assign it 100% to analyze it on its own or add delta hedging.
If you still need a source backtest, follow Create and run a backtest. Use the Strategy Library for examples you can adapt in the AI Editor.
Configure the analysis
- Requested start and Requested end: choose the period to analyze.
- Benchmark symbol: choose an underlying represented by the selected strategies for the performance comparison.
- Rebalance: choose when to restore fixed weights or calculate new inverse-volatility weights.
- Allocation: enter fixed percentages or configure the volatility calculation and lookback.
- Delta hedging: optionally enable hedge rules for one or more underlyings.
The allocation and rebalancing and delta-hedging guides explain these settings in detail.
Understand the available dates
The analysis uses the overlap between your requested dates and the data available for every selected backtest. For example, if one run covers 2020–2025 and another covers 2022–2025, their combined analysis can begin in 2022. Review any notice that the period was shortened.
Inverse-volatility allocation also reserves an opening lookback period for calculating volatility. That warm-up is excluded from the performance charts and statistics. Choose a period long enough to leave data for the analysis after warm-up.
Changing the requested dates analyzes existing data. To extend beyond the source backtests' coverage, use a portfolio rerun.
Analyze, review, and save
- Select Analyze and review to calculate a preview.
- Inspect Overview, Correlation matrix, Tearsheet, StatSim, and Events. Use the results guide to understand each view.
- To revise the setup, return to Configuration, change one setting, and analyze again.
- When the result matches the setup you want to keep, select Save portfolio.
Analysis creates a temporary preview. It becomes a saved portfolio only after you select Save portfolio. If you change the setup after analyzing, calculate a new preview before saving.
Find the saved result in Portfolios → Simulations.
Resolve missing data
If a selected run is unavailable or has incomplete analysis data, replace it with a finished run that contains the required data. Delta hedging may require rerunning an older backtest; intraday hedging also requires an appropriate data frequency. Follow the message identifying the affected strategy, then analyze again.
