Stock Market Week 48/25: RENIXX Recovers Strongly - Bloom Energy, Canadian Solar, Sunrun, Daqo, Cadeler And Enphase With Double-Digit Gains
Münster (Germany) - After a sharp pullback the previous week, the RENIXX World recovered significantly last week. At the close of trading, the RENIXX was up almost 7 percent. The best performer of the week was Bloom Energy with a gain of over 20 percent. Only a few stocks recorded losses.
Technical situation: RENIXX heading back toward the 1,200-point mark
From the end of 2023 to January 2025, the RENIXX moved sideways in a range between 1,000 and 1,200 points. The subsequent drop to 748 points marked a significant interim low and continues to represent the key support zone in the long-term chart. With a steady rise amid increasing volatility to almost 1,300 points, the index recently reached the upper end of the former trading range again - but the momentum proved insufficient. Profit-taking then pushed the index back down noticeably, at times close to the 1,000-point mark. A counter-movement is now underway. Year-to-date 2025, the RENIXX is now up 18.1 percent based on Friday’s closing price (previous week: 10.5%).

New test facility strengthens Nordex’s grid-integration expertise
Nordex is investing in its industrial future.

With the new test stand, Nordex can simulate diverse grid conditions without having to conduct field tests first, thereby shortening development times and improving the grid compatibility of its turbines.

Solaredge makes strong entry into the German commercial storage market
Solaredge is seeing high demand in Germany just weeks after launching its commercial storage system CSS-OD, with 150 orders already placed. The CSS-OD combines a battery cabinet with 102.4 kWh capacity and a 50 kW inverter. The solution is scalable up to 1 MWh per site and is designed for both indoor and outdoor installations. This opens up a new business area for installation companies, as existing commercial and industrial systems can reportedly be easily expanded with storage. Solaredge shares did not benefit, slipping 1.1 percent last week to €30.05.
