The M-Dax index has shown significant strength recently, moving towards its all-time high, primarily fueled by the domestic economy and supportive fiscal policies. This trend highlights the importance of the index selection for passive investments, particularly for medium- and long-term horizons, where success hinges more on the chosen index than on other factors like costs.

In the analysis of Germany's various selection indices—including Dax, M-Dax, S-Dax, and Tec-Dax—it becomes evident that the relative strength or weakness of an index often shows considerable stability over several years. Investors typically experience slow transitions to new favorite indices, underscoring the significance of index choice in investment strategy.

Moreover, the comparison of these indices has shifted noticeably since the recent government transition on May 6, 2025, reflecting an adaptation to new economic and fiscal landscapes. Each index’s performance may reveal insights about investor sentiment and broader market trends, making such analyses pivotal for investors aiming to navigate the evolving financial environment.
