Stock Market Week 14/26: RENIXX up +10.7% in Q1 - Market Observers see Shift in Priorities - Plug Power: Major Electrolyzer Order - Vestas and Nordex Continue Order Streak
Münster (Germany) - After the previous week’s losses, the RENIXX rebounded during the shortened trading week before Easter, but remains within the trading range of 1,200 to 1,300 points. Looking at the first quarter, the RENIXX is up nearly 11% in 2026 after the first three months.
Market observers see shift toward energy security
In light of geopolitical risks, market observers are increasingly focusing on energy security and domestic energy sources. According to a recent Reuters report, global renewable energy capacity increased by 692 GW in 2025 to more than 5,149 gigawatts in total - a new record that underscores the growing contribution of clean energy to global power supply.
This development is accompanied by strong investments in the energy transition: BloombergNEF’s annual report shows that global investment flows into the energy transition reached a new record of around USD 2.3 trillion in 2025. A large share went into clean technologies such as renewable energy, power grids, and electrification - even though the expansion of renewable projects in some regions declined slightly compared to the previous year.

Company news Week 14/26
Plug Power scores major order for 275 MW electrolyzer in Canada
The best-performing stock last week was Plug Power. The U.S.-based hydrogen and fuel cell specialist secured a major order for a hydrogen project in Canada. The company will supply a 275-megawatt electrolyzer system for Hy2gen’s “Courant” project - one of the largest projects of its kind to date. The plant will produce low-carbon ammonia and ammonium nitrate for the mining industry and will be powered by hydropower from Québec.
With a gain of 11.7% to EUR 2.10, Plug Power topped the RENIXX last week.
Vestas ends Q1 2026 with strong order intake - share price benefits
The Danish turbine manufacturer Vestas recorded remarkable order momentum over the past two weeks at the end of Q1. This has had a positive impact on its share price. Since March 23, 2026, Vestas has announced orders totaling 1,267 MW, with a focus on the United States. Europe follows with orders from Germany, Italy, France, and the UK. In addition, Vestas secured a major order from Brazil. Alongside turbine deliveries, the contracts also include long-term service and maintenance agreements.
Vestas shares rose 7.6% last week to EUR 24.72.
Nordex with new orders from NRW and world premiere in Brandenburg
The German wind turbine manufacturer Nordex also reported new orders last week. From Max Bögl, Nordex received a contract to supply and install six wind turbines for the Peckelsheim community wind farm in North Rhine-Westphalia. Turbines of the type N163/6.X will be used on 164-meter concrete-steel hybrid towers. In addition, STAWAG Energie GmbH ordered five N163/6.X turbines for the 35 MW Frettertal wind farm in the municipality of Finnentrop (Olpe district).
Beyond new orders, Nordex also reported a world premiere in Brandenburg: at the Mahlsdorf wind farm, a complete wind farm featuring the new Nordex N175/6.X turbine type has been connected to the grid for the first time. The turbines belong to Nordex’s Delta4000 platform and are designed for high energy yields with reduced electricity generation costs.
Nordex shares closed the week up 3.9% at EUR 44.94.
Technical situation: RENIXX at lower end of sideways range
From the end of 2023 to early January 2025, the RENIXX moved within a pronounced sideways range between 1,000 and 1,200 points. The notable interim low of 748 points in 2025 marked a key turning point and has since acted as a central support zone. From this low, the index has recovered significantly and reached a new annual high of 1,288.68 points on February 24, 2026 (previously: 1,279.06 points) - again at the upper end of the former trading range. However, a sustained breakout above this level has not yet occurred.
Currently, the RENIXX remains in a neutral sideways phase within the broader range. The support zone between 1,000 and 1,100 points continues to serve as a stabilizing anchor, while the 1,280 to 1,300 range acts as resistance.
RENIXX declines at the start of the week
In early trading of the new week, the RENIXX is slightly down. The biggest gainers are Plug Power, Meridian Energy, Ørsted, Xinyi Solar, and Verbund. Declines are seen in SolarEdge, Enphase Energy, JinkoSolar, Sunrun, and Ormat.
