Most active U.S. space-defense ETFs

Screening Filters

1. Price min: 5

   • Purpose: Excludes very low-priced securities.
   • Rationale: For “most active” ETFs, this helps avoid thin or less stable instruments that can distort activity readings. A $5 floor generally keeps the screen focused on more established, tradable ETFs with better liquidity.

2. Monthly average dollar volume min: 0

   • Purpose: Does not impose an additional liquidity cutoff.
   • Rationale: Since the user asked for the most active U.S. space-defense ETFs, the screen is intentionally not excluding any ETF on dollar-volume grounds. This allows the ranking to surface all eligible names in the theme, including those that may be active due to recent news or trading spikes.

3. Relative volume min: 1.5

   • Purpose: Finds ETFs trading at least 50% above their normal volume.
   • Rationale: This is the key “most active” filter. It captures unusual trading interest and helps identify ETFs currently seeing elevated participation, which is especially useful in a theme like space-defense where activity is often driven by headlines, contracts, or geopolitical catalysts.

4. Moving average relationship: PriceAboveMA20, PriceCrossAboveMA20

   • Purpose: Screens for ETFs with short-term price strength.
   • Rationale: ETFs trading above, or just crossing above, the 20-day moving average are showing improving momentum. That makes them more relevant if the user is looking for active names that are not only trading heavily but also demonstrating constructive price action.

5. Themes: Defense, Aerospace, Space, Industrials Equities, Technology Equities, Communications Equities

   • Purpose: Targets ETFs exposed to the space-defense ecosystem.
   • Rationale: “U.S. space-defense ETFs” can span multiple theme buckets because the underlying holdings may include defense contractors, aerospace manufacturers, satellite/space technology firms, and communications infrastructure names. Including these themes broadens the screen so it captures ETFs most likely tied to the requested sector.

6. Sector: Industrials, Technology, Communication Services

   • Purpose: Narrows results to the sectors most associated with space-defense exposure.
   • Rationale: Space-defense ETFs often hold companies in these sectors. Industrials cover defense and aerospace primes, Technology covers satellites, sensors, software, and advanced systems, and Communication Services can include satellite and communications-related businesses. This helps align the screen with the actual composition of ETFs in the theme.

Why Results Match:

• The query is about the most active U.S. space-defense ETFs, so the screen emphasizes elevated trading activity through relative volume.
• The theme and sector filters ensure the results are tied to space, defense, aerospace, and adjacent technology/communications exposures rather than unrelated ETFs.
• The moving average filter favors ETFs with positive short-term momentum, which often matters when looking for the most active and investable names.
• The price floor helps keep the results focused on tradable, established ETFs rather than lower-quality outliers.

In short, these filters aim to find ETFs that are both relevant to U.S. space-defense exposure and actively trading right now.
