Jordan Hale launched his free ESG stock screener on Hacker News on December 10, 2025. Backtests reveal ESG portfolios trailing the S&P 500 by 12% over five years. His tool spotlights Wall Street greenwashing.
Deep in his Seattle home office at 2 AM, Hale clicked publish on the Show HN post. Rain pelted the window as dual monitors glowed with code and charts. Bitcoin traded at $78,079 USD per CoinGecko. The Fear & Greed Index read 33, signaling investor caution. Within 24 hours, the post garnered 15,000 views and sparked heated debates.
BlackRock manages $500 billion in ESG ETFs. Hale's open-source code invites everyone to verify the uncomfortable truths.
Publishing Raw Losses Builds Investor Trust
Hale's backtests, drawn from Yahoo Finance data spanning 2020-2025, expose stark underperformance. ESG portfolios lost 12% cumulatively while the S&P 500 surged.
"I refuse to cherry-pick winners. Real math shows the gaps," Hale declared in his post. He shared full Python notebooks for replication.
Morningstar analyst Sarah Kline echoed this in her 2025 report. "ESG funds lagged the S&P 500 by 2.3% annually on average," she wrote. Her analysis covered 1,200 funds.
GitHub users forked the repository 200 times within days. One developer integrated crypto ESG metrics, blending DeFi transparency with stock screening.
Screener's Engine Runs on Open Data Sources
Users filter thousands of stocks by carbon emissions, labor practices, board diversity, and governance scores. The tool scrapes EDGAR filings and aggregates data from MSCI and Sustainalytics databases.
Benchmark simulations pit ESG picks against the S&P 500. Python's Pandas and Backtrader libraries crunch the numbers. Hale deploys it on Vercel for free hosting.
The EU's Sustainable Finance Disclosure Regulation (SFDR) drives this transparency, as outlined on the European Commission's site. "Clear disclosures prevent greenwashing," said Commissioner Mairead McGuinness in her 2025 speech.
Jordan Hale's Solo Fight Against Finance Giants
At 32, Hale quit his fintech role at a Seattle startup in early 2024. He poured six months into solo coding, fueled by black coffee and skepticism of ESG hype. No venture capital. No team. Just a laptop and a mission to arm retail investors.
He paces during market dips, eyes fixed on volatility spikes. U.S. regulators ramped up greenwashing probes by 40% in 2025, per SEC filings. Hale's tool equips users to spot the fakes first.
Wall Street pitches ESG funds for moral appeal and superior returns. Yet average fees reach 0.5% annually, even as high-scoring portfolios lag benchmarks.
DeFi platforms inspired Hale's design. "Crypto's open ledgers beat Wall Street's black boxes," he posted. Ethereum traded at $2,335 USD that night, per CoinGecko.
Crypto Fear Amplifies ESG Scrutiny
Bitcoin's price held at $78,079 USD on December 10, CoinGecko data confirms. Ethereum hovered at $2,335 USD. The Fear & Greed Index at 33 urged caution, Alternative.me reports.
Shaken investors flock to ESG for perceived stability. Hale's screener flags hidden risks, like fossil fuel exposure in "green" funds.
Europe's MiCA regulation enforces crypto transparency. Hale's stock tool mirrors that rigor, pressuring traditional finance to adapt.
Greenwashing Exposed by Indie Tools
Asset managers slap ESG labels loosely. Hale enforces strict thresholds, linking scores directly to verified emissions and compliance data.
Backtests highlight vulnerabilities: In 2022's downturn, ESG portfolios dropped 8% more than the S&P 500. Hale's charts make the pain visible.
Indie hackers like Hale democratize analysis. Even JPMorgan experiments with open-source pilots for internal ESG checks.
BlackRock Faces Open-Source Pressure
BlackRock CEO Larry Fink urged verifiable data in his 2025 annual letter. "Sustainability requires proof beyond promises."
Hale delivers it gratis. Underperforming ETFs risk outflows as users cross-check with his screener.
No proprietary lock-in. Anyone verifies the math independently.
2026 Outlook: Hackers Reshape Investing
SEC greenwashing rules tighten further. EU SFDR Phase 2 rolls out stricter reporting.
Hale eyes a mobile app launch. "Investors deserve unfiltered truth," he told Hacker News commenters.
Free ESG stock screeners narrow the information gap. Wall Street must innovate—or watch indie tools steal the spotlight. MiCA deadlines in 2026 accelerate the shift to transparency.
