Everything you need to get started with building portfolios in Timeline is right here. This guide walks you through the entire process—from adding funds and setting weightings, to selecting the right start date—so you can analyse performance with confidence and precision.
Description
Timeline offers advisers the ability to build bespoke investment portfolios. This feature is ideal for comparing tailored fund combinations against our pre-built model portfolios. The process is intuitive but requires attention to detail, particularly around fund weightings and the start date.
1. Access via the Analytics tab:
To begin, navigate to the Analytics tab, and click "Custom Portfolios."

You’ll be taken to the Custom Portfolio Centre, this is where your existing, prebuilt custom portfolios are stored should you wish to edit them. Then click “+ New model portfolio” in the top right

2. Naming & Start Date:
You’ll then be prompted to enter a portfolio name and set the start date.
⚠️ The start date must be after the date of the youngest fund in the portfolio. This ensures valid historical performance analysis in the system.
3. Adding Funds (3 Methods):
You have three flexible ways to add funds:

- Copy & Paste from Excel:
- Column A: ISIN code
- Column B: Weighting (e.g., 0.5 for 50%)
- Import from FE Analytics:
- Requires FE Analytics license
- Follow prompts after clicking “Import from FE Analytics”
- Add New Fund Manually:
- Search by ISIN or CITI code:

After adding all desired funds and weightings, click "Save and Continue."
Conclusion
Building custom portfolios in Timeline is a powerful way to model tailored investment strategies and compare them against different models. Just remember to align your start date with the youngest fund and enter weightings accurately. Once saved, your custom portfolio will be available for selection and analysis under the “Custom” filter.
