What would u buy

Screening Filters

1. relative_vol ≥ 1.5

   • Purpose: Find stocks with noticeably elevated trading activity.
   • Rationale: Since the user is asking which of RKLB, ASTS, or IRDM to buy in a short-term, Starlink-related context, higher relative volume helps identify names that are attracting attention and may be experiencing stronger momentum or a catalyst-driven move. This is especially useful for RKLB and ASTS, which tend to trade more actively when the space theme is in focus.

2. PriceAboveMA20

   • Purpose: Screen for stocks trading above their short-term trend.
   • Rationale: A stock above its 20-day moving average is generally showing near-term strength. For a tactical comparison between these space/satellite names, this helps favor candidates that are already acting well rather than trying to catch a falling stock.

3. PriceAboveMA200

   • Purpose: Confirm the stock is also above its long-term trend.
   • Rationale: This adds a higher-quality momentum check. A stock above both the 20-day and 200-day moving averages is often in a stronger technical position, which is relevant when deciding between speculative names like ASTS and more established ones like IRDM.

4. rsi_category = moderate

   • Purpose: Avoid extremely overbought or extremely weak stocks.
   • Rationale: Moderate RSI suggests the stock has room to continue moving without being too stretched. That’s useful in a stock-picking question because it helps exclude names that may already be overextended after a sharp run, while still keeping stocks with healthy momentum.

5. themes = Space Economy, Telecommunications Services, Aerospace & Defense

   • Purpose: Keep the screen focused on the same economic and industry themes as the user’s request.
   • Rationale: RKLB, ASTS, and IRDM all fit into the broader space/satellite connectivity universe. These themes are the most relevant business categories for a Starlink proxy comparison, so they ensure the results stay centered on the user’s intended area.

6. is_optionable = True

   • Purpose: Restrict the list to stocks with listed options.
   • Rationale: For speculative or momentum-oriented names, optionability is important because it usually reflects better liquidity and gives the trader flexibility to express a bullish view. This matters particularly for names like ASTS and RKLB, which are often traded tactically.

7. option_sentiments = Bullish

   • Purpose: Favor names where options traders are leaning positive.
   • Rationale: Bullish options sentiment can indicate informed traders or market participants are positioning for upside. In a comparison among RKLB, ASTS, and IRDM, this helps surface the stock that the options market currently favors most.

Why Results Match

• The filters are built for a short-term bullish stock selection, which matches the spirit of “What would you buy?” better than a long-term valuation screen.
• The theme filters ensure the results stay within the user’s Starlink proxy universe: space, satellite communications, and defense-adjacent names.
• The trend and momentum filters (PriceAboveMA20, PriceAboveMA200, and relative_vol) help identify which of these stocks is currently strongest technically, which is often the most useful factor for a tactical buy decision.
• The moderate RSI filter avoids chasing stocks that may already be too overbought, improving the quality of the comparison.
• The options and bullish sentiment filters add a market-implied vote of confidence and focus on liquid, tradable names that are more relevant for an active investor.

Overall, these filters are appropriate because they narrow the universe to space-related, tradable, technically strong stocks with supportive sentiment, which is exactly the type of setup you’d want when comparing RKLB, ASTS, and IRDM.
