Custom Indexing
Build Customizable Stock Portfolios Modeled on Index ETFs
The IBKR Advantage
- Create and customize direct index models based on a wide variety of US based ETFs.
- Modify target weights or use a customized rules module that supports ESG-related exclusion lists.
- Overweight or underweight stocks related to benchmark weights on a variety of financial metrics.
- Unlike traditional ETF investing, Custom Indexing does not have an expense ratio, allows you to customize and personalize investing to your client’s needs and comes with low minimums.
Our Custom Indexing tool makes it easy for advisors to build portfolios that are modeled after Index ETFs and easily customizable for client investment goals. Unlike ETFs, clients own fractional shares of each component stock, so advisors can adjust weightings and exclude stocks or sectors in accordance with client needs.
How It Works
As an illustrative example, the SPY ETF, which tracks the SPDR S&P 500, is comprised of over 500 stocks, each with its own weighting. Using Custom Indexing, advisors can copy a list of SPY’s individual holdings and weightings, save the list as a customized index and deploy it as a model that can be tailored to your strategy or client needs.
Custom Indexing offers several advantages over ETFs:
- No expense ratio
- Low commissions
- Low minimums
- Customize and personalize models to suit client needs
In addition, advisors can:
- Set cash targets
- Exclude any selected stocks
- Apply ESG-related exclusion lists (e.g., “Fossil fuels”)
- Set custom rules (e.g exclude small cap stocks; overweight stocks where PE is within a certain range and stock is in a particular sector; and so on)
- Swap stocks in the model for stocks you want to own with a single click.
