Stock Market Week 29/26: RENIXX Weaker as Bloom Energy, Goldwind and Ballard Power Drop by Double Digits
Münster — The RENIXX World came under pressure during a volatile trading week, weighed down primarily by sharp declines in fuel cell and wind stocks, while select electric mobility and solar names managed to buck the weak overall market trend.
Analyst and Market Drivers in Focus
The Iran conflict escalated again: after the ceasefire ended on July 8, the United States struck bridges in Iran on July 17, sending oil prices higher (Brent at USD 85.90, WTI at USD 80.90, as of July 17). The European Central Bank had already raised interest rates on June 11 for the first time since 2023 due to elevated inflation (3.2 percent in May), lifting the deposit rate to 2.25 percent; its next meeting is scheduled for July 23, while the US Federal Reserve is holding its rate pause for now. Higher interest rates make project financing for renewables more expensive, though rising oil prices are strengthening their relative competitiveness as a counterbalance.
Climate policy also drew attention: Turkey's incoming COP31 presidency is putting a global electrification target on the UN climate conference agenda for the first time (November 9-20, 2026, in Antalya). The target calls for electricity's share of global final energy consumption to rise from around 20 percent to 35 percent by 2035. According to IRENA data published on July 14, 2026, renewables accounted for 31.7 percent of global electricity generation in 2024, a record 9,836 TWh, up 9.8 percent year-on-year. Meeting the COP31 target would require that share to climb to around 78 percent by 2035.
Company News in Week 29
BYD Energy Storage has secured its first major order from Masdar to supply battery storage systems for the world's largest battery storage project. The round-the-clock (RTC) project, developed by Masdar and the Emirates Water and Electricity Company (EWEC), combines a 5.2 GW photovoltaic plant with a 19 GWh battery storage system. BYD shares rose 3.2 percent last week to EUR 9.85.
Sunrun is aggregating tens of thousands of home battery systems into one of California's largest virtual power plants. More than 80,000 households with over 110,000 battery storage systems are now participating in the virtual power plant this year, a fivefold increase from around 16,000 customers at launch in 2024. The storage systems are being coordinated for the first time through two California grid services programs: the California Energy Commission's Demand Side Grid Support Program and the California Public Utilities Commission's Emergency Load Reduction Program. Sunrun shares fell 4.4 percent last week to EUR 10.40.
Bloom Energy came under pressure after short seller Hunterbrook Media published a report on July 7-8, 2026, alleging that the fuel cell maker remains dependent on Chinese scandium oxide, a key production material, despite claims to the contrary, and that it is overstating its order backlog. The stock briefly lost as much as 12 percent following the report; Bloom Energy rejected the allegations in an SEC filing on July 9, 2026. Short seller reports of this kind are an established but controversial market instrument in the United States, and the allegations remain unconfirmed. Bloom Energy shares fell 14.2 percent last week to EUR 185.40.
Technical Picture: Testing the 200-Day Moving Average
Since reaching its 52-week high of 1,533.57 points on June 2, 2026, the RENIXX World has been in a downtrend, shedding around 272 points. With the index falling below the round 1,300-point mark during the week, the 200-day moving average, currently at 1,257.80 points and previously acting as support, has come within immediate reach of the index for the first time in months.
The index closed the reporting week at 1,261.83 points (Friday, July 17, 2026), just around 4 points above the 200-day moving average and well below both the 20-day moving average (1,338.25 points) and the 50-day moving average (1,399.93 points). Whether the 200-day line holds as support is the key open question for the broader uptrend that has been in place since mid-2025: as long as the roughly 1,258-point mark holds, the trend remains formally intact, while a sustained break would call the support level into question. The 14-day RSI at 39.6 offers no clear signal either way, indicating a neutral market condition without extreme oversold readings.
RENIXX Mixed at Start of New Week
At the start of the new trading week, the RENIXX is trading slightly higher. The biggest early gainers are China Longyuan, CATL, BYD, Jinkosolar and Daqo New Energy. On the losing side are Array Technologies, Canadian Solar, Sunrun, Enphase Energy and Grenergy Renovables.
