Stocks connected to spaceX

Screening Filters

1. monthly_average_dollar_volume ≥ 500,000

   • Purpose: Ensure the stocks are reasonably liquid and actively traded.
   • Rationale: “Connected to SpaceX” names people care about tend to be larger, well‑followed companies (e.g., suppliers, partners, satellite/launch ecosystem players). A minimum dollar volume threshold filters out illiquid micro‑caps that might nominally be in “space” but are hard to trade and often low quality or speculative.

2. industry ∈ {Aerospace & Defense, Telecommunications Services}

   • Purpose: Target industries that are most likely to have operational or commercial links to SpaceX.
   • Rationale:
     • Aerospace & Defense includes launch providers, satellite manufacturers, avionics, and defense contractors that may be suppliers, competitors, or partners in the launch/satellite ecosystem SpaceX operates in.
     • Telecommunications Services captures satellite communications, broadband, and related network providers that might partner with, compete with, or be strategically affected by Starlink (SpaceX’s satellite internet business).

3. themes ∈ {Aerospace & Defense, Space Economy}

   • Purpose: Refine results to companies thematically involved in space and defense, not just broadly in related sectors.
   • Rationale: Sector/industry labels can be broad. A telecom company might focus purely on terrestrial fiber, while another is heavily exposed to satellites. Using thematic tags like Space Economy and Aerospace & Defense narrows the list to firms where space‑related activities are material to the business, increasing the chance of real strategic or economic ties to SpaceX (e.g., satellite builders, launch infrastructure, space‑focused telecom).

4. is_index_component ∈ {GSPC (S&P 500), RUT (Russell 2000), NDX (Nasdaq 100)}

   • Purpose: Focus on publicly traded, benchmark‑index constituents with established size, reporting, and analyst coverage.
   • Rationale: These indices capture most of the investable U.S. equity universe by size (large + small caps). Companies with meaningful relationships to SpaceX that investors typically talk about (major suppliers, competitors, ecosystem players) are more likely to be listed in these indices, improving quality and relevance while avoiding obscure names.

5. is_optionable = True

   • Purpose: Restrict to stocks that have listed options.
   • Rationale: Optionability is a rough proxy for investor interest, liquidity, and scale. Firms closely watched for their exposure to SpaceX or the broader space ecosystem tend to be large and liquid enough to have options. This eliminates many very small, speculative space‑themed stocks that might be loosely related but not central ecosystem players.

Why Results Match the Question (“stocks connected to SpaceX”)

• The industry and theme filters concentrate on the core parts of the economy where SpaceX operates: launch, satellites, defense, and satellite communications. This is where real commercial, competitive, or supplier relationships are most likely.
• The index membership, liquidity, and optionability filters ensure the output is a practical, tradable list of established companies that the market actually treats as meaningful players in the “SpaceX / space economy” narrative, rather than obscure micro‑caps.

This screen can’t guarantee a direct contractual relationship with SpaceX (those details often aren’t fully disclosed), but it systematically surfaces publicly traded companies most likely to be materially involved in the same ecosystem or to have economic exposure to SpaceX’s growth and activities.
