Stock Markets, Week 37/26: RENIXX World Nearly Unchanged, Bloom Energy and Nordex Lead Gains, Ormat Biggest Loser of the Week
Münster – The RENIXX World renewable energy stock index traded volatile last week. After testing the chart resistance zone identified the week before, the index failed to break through by midweek and fell to a weekly low on Thursday. It recovered toward the end of the week and closed almost unchanged from the previous week.
Weekly Winners and Losers
The RENIXX World closed at 1,223.84 points on Friday, September 11, 2026. Compared with the previous week's close of 1,223.12 points (September 4, 2026), this represents a gain of 0.1 percent, or 0.72 points. The week's biggest gainers were Bloom Energy (+9.0 percent), Nordex (+6.9 percent), Cadeler (+3.2 percent), Grenergy Renovables (+3.2 percent) and First Solar (+2.3 percent). On the losing side were Ormat Technologies (−9.2 percent), BYD (−6.8 percent), Daqo New Energy (−5.7 percent), CATL (−5.3 percent) and Ballard Power Systems (−5.0 percent). On a year-to-date basis, the RENIXX is up 8.3 percent, or 93.47 points, but remains around 21.1 percent below its 52-week high of 1,550.58 points, reached on June 3, 2026.
Technical Picture: Breakout Attempt Fails
Following its 52-week high of 1,550.58 points on June 3, 2026, the index approached the well-known neckline of a double-bottom formation at around 1,257 points on Tuesday, September 8, 2026, reaching 1,257.61 points. The breakout attempt failed, and the neckline remains an intact resistance level. By Thursday, September 10, 2026, the index had fallen to a weekly low of 1,205.74 points. On Friday, September 11, 2026, it closed at 1,223.84 points, up 0.1 percent from the previous week (September 4, 2026).
As long as the RENIXX remains below its 20-day moving average (1,238 points), 50-day moving average (1,260 points), 200-day moving average (1,276 points) and the neckline at around 1,257 points, the recovery attempt remains fragile; a breakout above the 1,257–1,276-point zone would be required for a trend reversal. On the downside, the zone between 1,190 and 1,200 points has repeatedly proven to be support since February/March 2026 — including a low of 1,189.71 points on March 6 — and has not been sustainably breached since. The downtrend that began on June 3, 2026, remains intact.
RENIXX World at the Start of the New Week
In early trading in the new week, the RENIXX is declining. The biggest losses are being recorded by Bloom Energy, Canadian Solar, EDP Renewables, Grenergy Renovables and Ørsted. The strongest gains are being posted by Xpeng, China Longyuan Power, Goldwind Science & Technology, JinkoSolar and CATL.
