First Solar Surges on Landmark Spain Solar Deal Ranks 430th in U.S. Trading Volume

On October 8, 2025, First Solar (FSLR) closed with a 1.53% gain, trading on a volume of $0.26 billion, ranking 430th in terms of trading activity among U.S. equities. The stock's performance was influenced by a strategic partnership announced with a European energy firm to supply photovoltaic modules for a 1.2-gigawatt solar project in Spain. The agreement, valued at approximately $450 million, marks First Solar's largest international contract since 2023 and includes a 10-year supply commitment with volume escalations tied to project phase completions.

Analysts highlighted the deal's significance as a validation of First Solar's module technology in competitive global markets. The contract also secures long-term revenue visibility amid sector-wide supply chain uncertainties. However, questions remain about the company's ability to maintain profit margins given recent raw material price volatility. The announcement coincided with broader market skepticism toward renewable energy stocks following mixed Q3 earnings reports from peers in the solar and wind sectors.

Additional catalysts included a regulatory update from the U.S. Department of Energy, which expanded tax credit eligibility for solar projects using domestically manufactured components. First Solar's recent capital expenditure guidance, announced in early October, aligns with this policy shift by prioritizing U.S. plant expansions over overseas production. The company also confirmed plans to allocate 30% of its 2026 R&D budget to next-generation thin-film technology development, potentially enhancing efficiency metrics in its product portfolio.

To run this back-test accurately I need to pin down a few practical details: 1. Market universe • Do we rank all U.S. listed stocks each day, or a narrower universe (e.g., S&P 500 constituents, NASDAQ-100, etc.)? • If you have a preferred exchange or symbol list, let me know. 2. Trading convention • Should we buy at today’s open and sell at today’s close, or buy at today’s close and sell at tomorrow’s close (i.e., a full 1-day holding period)? • Equal-weight across the 500 names, or volume-weighted / dollar-weighted? 3. Data assumptions • Corporate-action-adjusted prices (split-/dividend-adjusted) by default—OK? • Transaction costs or slippage to include? Once I have this information I’ll run the ranking each day, form the daily 500-stock basket, and calculate the aggregated portfolio return from 2022-01-01 to present.
