DAX Developments in May 2025: Winners and Losers at a Glance

Market Overview in May 2025

In May 2025, significant market developments led to noticeable movement in the DAX. The performance of individual DAX stocks varied widely, which is of high relevance for both private investors and small shareholders. The DAX itself showed strong performance in the year 2025 so far: by May 20, the index was already around 20.7 percent above the previous year’s value. In May, the index fluctuated between an opening value of about 22,649 points and a closing value of around 22,819 points – a moderate increase of about 0.8 percent according to forecasts. However, the actual closing prices at the end of May were significantly higher.

Biggest Winners in the DAX (May 2025)

The ranking of top performers is not fully listed in the available sources; primarily, the flop stocks are specifically mentioned. However, other reports indicate that there were notable winners as well – these are usually only summarized or not explicitly listed.

Typically, in such dynamic months, stocks from the technology sector or companies with positive quarterly results are often among the winners – concrete names are, however, missing in the currently available rankings for May.

Summary

Losers:

  • Sartorius vz (-7.09 %)
  • Merck (-5.25 %)
  • Munich Re (-5.02 %)
  • BASF (-5 %)
  • Allianz (-4.23 %)

Winners: Not explicitly named in current rankings; usually technology companies or stocks with positive quarterly results.

The overall market remained robust despite individual setbacks and continued to show a positive trend over the year.

For private investors, it is particularly relevant to know: The performance of individual stocks can diverge significantly from the overall market – diversification remains an important tool for risk dispersion. Even if some major stocks like Sartorius vz or Merck struggled, the overall index remained stable or slightly rising.

A detailed list of all top winners would be desirable; however, it is currently not available or has not been published in the main sources.
