New stocks hitting the market today

Screening Filters

1. region: ['US']

   • Purpose: Limits results to companies listed in the United States.
   • Rationale:
     • The question asks generally about “new stocks entering the market today” without specifying a country.
     • By defaulting to the U.S. market, the screener focuses on the largest, most liquid, and most commonly followed equity markets, where IPO and new listing data is tracked reliably.
     • This avoids pulling in obscure or illiquid listings from many different countries that might not match what most users mean by “the market” unless they specify a different region.

2. list_exchange: ['XNYS', 'XNAS', 'XASE']

   • Purpose: Restricts results to stocks listed on the main U.S. exchanges:
     • XNYS – New York Stock Exchange (NYSE)
     • XNAS – NASDAQ
     • XASE – NYSE American (formerly AMEX)
   • Rationale:
     • New “stocks entering the market” usually refers to IPOs and new primary listings on major exchanges, not over-the-counter (OTC) or pink sheet securities.
     • Focusing on NYSE, NASDAQ, and NYSE American ensures the screener captures the core set of U.S. IPOs and new listings that most investors care about.
     • It filters out less regulated venues and non-exchange-traded instruments, keeping the list aligned with typical investable stock universes.

Why Results Match the User’s Request

• By combining region: US with the three main U.S. exchanges, the screener is effectively looking for companies that have just started trading today on major U.S. stock markets—which is the practical definition of “new stocks entering the market today” for most investors.
• The filters exclude foreign markets and non-exchange venues, so the resulting stocks are the most relevant, widely followed “new entrants” rather than obscure or illiquid listings.
