Münster (Germany) – The RENIXX World was unable to continue its upward trend last week and failed to reach the yearly high of 1,180.39 points. During the week, the index fell to 1,087 points but managed to recover by Friday. At the end of the week, the RENIXX closed at the same level as the previous week.

The global renewable energy stock index RENIXX World (ISIN: DE000RENX014) rose slightly by 0.2 percent last week, closing at 1,144.27 points (closing price October 24, 2025). This is just below the yearly high, which the RENIXX marked at 1,180.39 points on October 16, 2025.

Technical Overview: RENIXX Nears 1,200-Point Level

From the end of 2023 to January 2025, the RENIXX traded in a sideways range between 1,000 and 1,200 points. The subsequent drop to 748 points marked the “head” of an inverse head-and-shoulders pattern. With the current rise to 1,180 points, the index has returned to the upper edge of its previous range. The recent pullback to 1,087 points is within the expected range. Indications of a possible trend reversal are strengthening, which, if confirmed, could open further upside potential. On a year-to-date basis in 2025, the RENIXX now stands at +16.5% after Friday’s close (previous week: +16.2%).
