Medical and tech

Screening Filters

1. sector: ['Healthcare', 'Technology']

   • Purpose: Limits results to companies operating in the medical/health-related space and in technology.
   • Rationale:
     • Your request: “US stocks in the medical and technology sectors.”
     • In most financial databases, “medical” is captured under the broader Healthcare sector (which includes pharmaceuticals, medical devices, healthcare services, biotech, etc.).
     • “Technology” directly corresponds to the Technology sector (software, semiconductors, hardware, IT services, etc.).
     • Using these two sector filters ensures we’re focusing precisely on the types of businesses you asked for.

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

   • Purpose: Restricts results to stocks listed on the major US exchanges:
     • XNYS – New York Stock Exchange (NYSE)
     • XNAS – NASDAQ
     • XASE – NYSE American (formerly AMEX)
   • Rationale:
     • You specified US stocks. Stocks listed on these three exchanges are considered primary US-listed equities.
     • This excludes foreign exchanges and OTC markets, aligning the universe with US-listed companies only.
     • These exchanges generally provide better liquidity, more rigorous listing standards, and more reliable financial disclosure.

Why Results Match:

• Your request was: “Please screen for US stocks in the medical and technology sectors.”
• “Medical” is implemented as the Healthcare sector, which is the standard classification that covers medical-related businesses.
• “Technology” is implemented directly via the Technology sector filter.
• Limiting to XNYS, XNAS, and XASE effectively targets US-listed stocks, fulfilling the “US stocks” requirement.

So the filters used do match your request in a practical, database-ready way:

• Sector filters = medical (via Healthcare) + technology
• Exchange filters = US stock markets (NYSE, NASDAQ, NYSE American)

As a reminder, while we can screen for sectors and exchanges that fit your criteria, no screen can guarantee which stocks “will go up a lot tomorrow.” These filters just define what kind of stocks you’re looking at, not their short-term price movements.
