Welcome to the September 2024 edition of our release notes. This update provides a comprehensive overview of the latest enhancements to the Polygon.io platform, featuring new tools, API functionalities, and educational content designed to improve your experience and capabilities.
This section highlights the latest enhancements and additions to the Polygon.io platform. From infrastructure upgrades to new functionalities, these developments are designed to improve service performance and user experience.
Polygon.io has expanded its infrastructure with a new data center in Chicago, now fully operational and serving live traffic. This addition complements our Equinix NY campus data center, enabling us to operate two dedicated facilities that improve service performance and reliability through added redundancy and decreased latency for all users.
Our Ticker News API has been upgraded to include advanced sentiment analysis, utilizing Large Language Models (LLMs) to extract structured insights such as ticker mentions, sentiment, and summaries from unstructured financial news. This enhancement enables users to monitor sentiment trends efficiently for specific tickers, providing a valuable tool for market analysis.
Here’s a simple example of how to retrieve news insights for a ticker using the API:
from polygon import RESTClient client = RESTClient() # Fetch news articles for 'AAPL' with insights news_articles = client.list_ticker_news( "AAPL", params={"published_utc.gte": "2024-09-03"}, order="desc", limit=1000 ) # Display the title and insights for each article for article in news_articles: print(f"{article.title} [Insights = {article.insights}]")
Here's an example of the Insights object that showcases these enhancements:
Title: Apple, Nvidia Key Supplier TSMC Leads Taiwanese Chip Giants To Localize Neon Gas Production By 2025 Insights = [ Insight( sentiment="positive", sentiment_reasoning="TSMC is leading the initiative to localize neon gas production, which is a significant step towards enhancing supply chain reliability for the Taiwanese semiconductor industry.", ticker="TSM", ), Insight( sentiment="positive", sentiment_reasoning="UMC is considering purchasing locally produced neon gas from Linde LienHwa, further supporting the initiative to localize neon gas production.", ticker="UMC", ), Insight( sentiment="positive", sentiment_reasoning="TSMC, a key supplier for Nvidia, is leading the effort to localize neon gas production, which will benefit Nvidia's supply chain.", ticker="NVDA", ), ]

We are excited to introduce the Related Companies API, a new feature designed to identify and analyze connections between companies based on news articles and financial data. This innovative tool can help you uncover inter-company relationships across various sectors.
Here’s a simple example of how to retrieve related companies for a ticker using the API:
from polygon import RESTClient client = RESTClient() # Retrieve and display companies related to Apple Inc. related_companies = client.get_related_companies("AAPL") print(related_companies)
Here's an example of the related companies being returned:
$ python examples/rest/stocks-related_companies.py [ RelatedCompany(ticker="MSFT"), RelatedCompany(ticker="GOOGL"), RelatedCompany(ticker="AMZN"), RelatedCompany(ticker="GOOG"), RelatedCompany(ticker="TSLA"), RelatedCompany(ticker="NVDA"), RelatedCompany(ticker="META"), RelatedCompany(ticker="NFLX"), RelatedCompany(ticker="DIS"), RelatedCompany(ticker="BRK.B"), ]
