Overview: DAX Performance in May 2025
In May 2025, the DAX exhibited a significant dynamic, with individual stocks recording strong price movements. The analysis of the biggest winners and losers is particularly relevant for investors to better assess opportunities and risks in the current market environment. The DAX itself has shown robust development in the year 2025 so far, standing at an increase of +20.7 percent compared to the previous year as of May 20th. However, there were also noticeable fluctuations within the index in May.
Biggest Losers in the DAX (May 2025)
The following companies were among the biggest losers of the month (based on Xetra prices between April 30, 2025, and May 30, 2025):
- Sartorius vz: -7.09 %
- Merck: -5.25 %
- Munich Re: -5.02 %
- BASF: -5.00 %
- Allianz: -4.23 %
These values indicate a clear weakness in the areas of biotechnology (Sartorius), pharmaceuticals/chemicals (Merck), insurance/reinsurance (Munich Re), and chemicals/basic chemicals (BASF).
Biggest Winners on Ranking Day
For individual trading days, there are also current top winners. For example, on May 30th, the biggest daily winners were:
| Company | Performance (%) |
|---|---|
| Beiersdorf AG | +0.66 |
| Heidelberg Materials | +0.63 |
| Siemens Energy | +0.61 |
| Allianz SE | +0.60 |
| E.ON SE | +0.58 |
Beiersdorf benefited from its defensive character in uncertain markets; Heidelberg Materials from declining financing costs; Siemens Energy through positive impulses from wind power and infrastructure investments; Allianz through stable capital allocation; E.ON as a defensive provider with attractive valuations amid hopes for interest rate cuts.
Note: The daily winners list does not necessarily reflect the monthly top performers.
Summary
Monthly Losers were primarily stocks from defensive sectors such as chemicals/pharmaceuticals as well as insurance/reinsurance – possibly a sign of sector weakness or valuation adjustments. In contrast, Daily Winners benefited from defensiveness or specific market impulses such as expectations of interest rate cuts or infrastructure investments.
A detailed monthly list of absolute top winners is not explicitly listed in the available rankings – they primarily focus on the flops or underperformers. For investors, it remains important: even within an overall strongly rising index, there are significant differences between individual values – diversification remains crucial for risk spreading.
