Bank Reuse Explained
How often a strategy appears across your retained portfolio bank, and why it matters.
Bank Reuse tells you how frequently one strategy appears across your entire retained portfolio bank — the full set of portfolios SIPS has generated and kept for you.
What it means
If a strategy is used in a large share of your portfolios, its own ups and downs will be felt across many of those portfolios at once. A strategy used in very few portfolios contributes something more distinctive.
The bands
The same three bands are used everywhere Bank Reuse appears in SIPS:
- Low — 20% or less of the bank
- Moderate — between 20% and 50%
- High — more than 50%
Why it matters
Lower reuse can support a portfolio’s own distinctiveness within your bank, because fewer of its member strategies are shared with your other retained portfolios.
You’ll see Bank Reuse on Portfolio Comparison (Top Reused Strategies and the Bank Reuse Mix column), on Portfolio Analysis, in the Custom Builder draft table and in Portfolio Log. Custom Portfolios are measured against your current retained bank.
Please note
Bank Reuse is information only. It is never used as a Portfolio Builder rule, a ranking score or a Portfolio Settings value.
