How to Find Public Companies by Industry

Whether you're looking for companies in the technology, healthcare, energy, or financial sector, organizing businesses by industry can make research much easier. It allows investors to compare competitors, identify market leaders, and discover new investment opportunities.

Finding companies by industry

In this guide, we'll show you how to find public companies by industry and where to access reliable company information.

Why Search by Industry?

Grouping companies by industry makes it easier to:

  • Compare similar businesses
  • Research competitors
  • Identify industry trends
  • Build watchlists
  • Discover companies you may not have considered

For example, instead of researching one technology company, you can compare several companies operating in the same market.

Where to Find Public Companies

Several resources allow you to browse publicly traded companies by industry.

Common sources include:

  • Stock exchanges
  • Financial market websites
  • Company screeners
  • SEC filings
  • Investor research platforms

Many of these tools let you filter companies by sector, industry, market capitalization, exchange, and other criteria.

Research Companies Using SEC Filings

Once you've identified a company, its SEC filings provide detailed information about its business and financial performance.

Useful filings include:

  • 10-K - Annual reports
  • 10-Q - Quarterly reports
  • 8-K - Major company announcements
  • Proxy statements - Corporate governance information

These filings are available through the SEC's EDGAR database. For help locating them, read our guide to finding any company's SEC filings.

What Information Can You Compare?

When researching companies within the same industry, investors often compare:

  • Revenue growth
  • Profitability
  • Business model
  • Market position
  • Financial statements
  • Risk factors
  • Recent company developments

Reviewing these metrics across multiple businesses can provide a better understanding of the industry as a whole.

Build a Watchlist

After identifying companies that interest you, consider creating a watchlist.

Tracking a consistent group of companies makes it easier to:

  • Follow quarterly earnings
  • Monitor SEC filings
  • Compare financial performance over time
  • Stay informed about industry news

As you become familiar with an industry, comparing SEC filings between competitors can provide valuable insights into how different companies are performing.
