What ai chop makers went down today ?

Screening Filters

1. Market Cap ≥ $2,000,000,000

   • Purpose: Focus on larger, more established AI chip-related companies.
   • Rationale:
     • When users ask about “AI chip makers,” they usually mean well-known, significant players rather than tiny microcaps.
     • A $2B minimum market cap helps filter out very small, illiquid, or speculative names that may not be meaningful in the AI chip ecosystem.

2. Daily Volume ≥ 500,000 shares

   • Purpose: Ensure the stocks are actively traded and price moves are meaningful.
   • Rationale:
     • Higher volume reduces the impact of random or illiquid price moves.
     • When looking for “went down today,” this focuses on names where the decline reflects real market sentiment, not thin trading noise.

3. Price Change % ≤ 0 (Today)

   • Purpose: Capture stocks that were flat or declined today, with emphasis on those that went down.
   • Rationale:
     • The user asked about chip makers that “went down today.”
     • Setting the maximum daily price change at 0% ensures we only see names that did not rise today; most will be negative, i.e., they declined.

4. Industry: Semiconductors & Semiconductor Equipment

   • Purpose: Limit the universe to companies directly in the semiconductor value chain.
   • Rationale:
     • “AI chip makers” are part of the broader semiconductor industry.
     • Including “Semiconductors & Semiconductor Equipment” captures both direct chip manufacturers (designers and fabs) and closely related equipment/materials providers that are integral to AI chip production.

5. Themes: Semiconductor Equipment & Materials

   • Purpose: Emphasize companies tied specifically to chip production infrastructure.
   • Rationale:
     • Many “AI chip” stories involve not only the chip designers but also the equipment and materials companies enabling advanced AI chip manufacturing (e.g., lithography, deposition, testing).
     • This theme tag helps capture those that are structurally important to AI chip making.

6. Themes: AI Beneficiary

   • Purpose: Focus on companies whose business is meaningfully exposed to AI demand.
   • Rationale:
     • The user is specifically interested in “AI” chip makers, not just any semiconductor company.
     • The “AI Beneficiary” theme filters for firms whose revenue growth, product demand, or strategic positioning is tied to AI compute, AI accelerators, data center AI, etc.

7. Themes: Technology

   • Purpose: Ensure all results are within the broader technology sector.
   • Rationale:
     • AI chip makers are by definition tech companies.
     • This theme further filters out any peripheral or misclassified names and keeps the focus on core tech-related exposures.

Why Results Match the Question

• The industry and semiconductor-related themes ensure the list is centered on companies involved in making chips or supplying essential equipment/materials for AI chips.
• The AI Beneficiary theme narrows this to those specifically leveraged to AI, aligning with “AI chip makers” rather than generic semiconductors.
• The price_change_pct ≤ 0 filter directly addresses “went down today” by only including names that did not rise and predominantly declined.
• The market cap and volume filters keep the results focused on significant, actively traded companies where daily moves are relevant and observable to most investors.
