| Bar Chart and Performance Table [Heading] | PERFORMANCE INFORMATION | ||||||
| Performance Narrative [Text Block] | The following information provides some indication of the risks of investing in the Portfolio by showing how the Portfolio’s performance has varied over time. The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Portfolio’s average annual returns for the periods indicated to a broad-based securities market index and a style specific index. The indices are not available for direct investment. All figures assume reinvestment of dividends and distributions and include the effect of the Portfolio’s recurring expenses, but do not include fees and expenses of any variable annuity contract. If the fees and expenses of any variable annuity contract were reflected, the performance shown would be lower.
The Portfolio’s past performance does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/clayton-street-trust or by calling 1-800-668-0434. |
