Bar Chart and Performance Table [Heading] The Fund’s Performance
Performance Narrative [Text Block]
The Fund's investment objective and principal investment strategies are identical to those of the Predecessor Fund. Before the Predecessor Fund commenced operations, all of the assets and liabilities of the DSM Large Cap Growth Fund were transferred to the Predecessor Fund in a tax-free reorganization on August 15, 2016. As a result, the Predecessor Fund assumed the performance and accounting history of the DSM Large Cap Growth Fund.
The Fund is newly formed and will commence operations following the completion of the reorganization of the Predecessor Fund, a series of the Touchstone Strategic Trust, into the Fund, which is expected to occur on or about March 13, 2026 (the “Reorganization”). The performance and accounting history of the Predecessor Fund will be assumed by the Fund. Performance information included herein is that of the Predecessor Fund.
The bar chart and performance table below illustrate some indication of the risks and volatility of an investment in the Fund by showing changes in the Predecessor Fund’s performance from calendar year to calendar year and by showing how the Predecessor Fund’s average annual total returns for one year, five years, and ten years compare with the Russell 3000® Index. The Russell 1000® Growth Index shows how the Predecessor Fund’s performance compares against the returns of an index with similar investments. The bar chart does not reflect any sales charges, which would reduce your return. The performance table reflects any applicable sales charges. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. More recent performance information is available at no cost by visiting TouchstoneInvestments.com or by calling 1.833.368.7383.
