# Using Yahoo Finance News Tool

> Explains a lightweight Yahoo Finance News Tool that scrapes and returns recent headlines and short summaries for a given stock ticker, with usage, features, and best practices.

This lesson covers the Yahoo Finance News Tool — a lightweight utility that scrapes and returns recent headlines and short summaries for a given stock ticker from Yahoo Finance. It's particularly useful when building finance-focused [agents](https://learn.kodekloud.com/user/courses/ai-agents) or assistants that need up-to-date news context about a company.

## Quick start

Example usage:

```python theme={null}
from langchain_community.tools.yahoo_finance_news import YahooFinanceNewsTool

tool = YahooFinanceNewsTool()
res = tool.run("NVDA")
print(res)
```

Example output:

```plaintext theme={null}
Nvidia (NVDA) Rises But Trails Market: What Investors Should Know
Nvidia (NVDA) closed at $877.57 in the latest trading session, marking a +0.03% move from the prior day.
```

## What the tool returns

This tool scrapes the Yahoo Finance news pages for the provided ticker (for example, `NVDA`) and returns the most relevant or trending news headlines with short summary lines. The returned text commonly includes:

* Headline(s)
* Short summary or status lines (e.g., recent close price and percent change)
* Brief context that helps determine relevance for trading or research

## How it works

* It performs HTTP requests to the public Yahoo Finance news pages for the ticker.
* The tool extracts headlines and short metadata/summaries and formats them as plain text to be consumed directly or fed into an agent pipeline.
* Designed for quick lookups; it is not a full news-aggregation system.

## Feature summary

| Feature        | Details                                                                          |
| -------------- | -------------------------------------------------------------------------------- |
| Input          | A stock ticker symbol (e.g., `NVDA`)                                             |
| Output         | Plain text containing headline(s) and short summaries                            |
| Source         | Yahoo Finance news pages (e.g., `https://finance.yahoo.com/quote/<TICKER>/news`) |
| Typical fields | Headline, short summary/status (close price, percent change)                     |
| Use cases      | Real-time agent context, stock research assistants, quick news checks            |

## Why it is useful

* Adds timely news context to trading agents or research workflows.
* Helps agents detect sentiment shifts or material events that may influence decisions.
* Lightweight and easy to integrate into a toolchain or agent toolkit.

## Best practices

* Cache results to reduce repeated scraping for the same ticker within short time windows.
* Implement error handling and retries for transient network errors.
* Combine with price/time-series tools for richer decision-making context rather than relying on headlines alone.

## Notes and considerations

<Callout icon="lightbulb" color="#1CB2FE">
  The tool scrapes publicly available pages on Yahoo Finance. Be mindful of rate limits and Yahoo's terms of service. Because scraped content can change rapidly, consider caching results and adding robust network error handling in production systems.
</Callout>

<Callout icon="warning" color="#FF6B6B">
  This tool is a scraper of third‑party web pages. Always review Yahoo Finance's terms of service before using scraped data in production, and avoid excessive request rates. For high-volume or commercial use, seek official APIs or licensing options.
