What do I buy?

Screening Filters

1. beta: LowRisk, ModerateRisk

   • Purpose: Focus on stocks with lower to moderate volatility relative to the overall market.
   • Rationale: When someone broadly asks “What financial assets should I consider buying?”, a reasonable interpretation is that they’re looking for candidates that are not excessively risky.
     • A low beta stock tends to move less than the market (less downside in sharp sell‑offs, but also less upside in rallies).
     • A moderate beta stock still participates in market moves but isn’t extremely volatile.
       This helps surface names that are more suitable as core holdings rather than speculative trades.

2. is_index_component: GSPC (S&P 500)

   • Purpose: Limit results to companies that are part of the S&P 500 index.
   • Rationale: The S&P 500 is a widely followed benchmark of large, established U.S. companies. These firms typically have:
     • Larger market caps
     • Better liquidity (easier to buy/sell)
     • More analyst coverage and disclosure
       For someone asking generally what to consider buying, starting with large, well-known companies is a conservative and practical approach.

3. list_exchange: XNYS, XNAS, XASE (NYSE, NASDAQ, AMEX)

   • Purpose: Include only stocks listed on major U.S. exchanges.
   • Rationale: Major exchanges enforce listing standards, which usually translates into:
     • Higher reporting quality and transparency
     • Greater liquidity and narrower bid–ask spreads
       This filter keeps the universe to widely traded, regulated U.S. stocks, which are more accessible and suitable for most investors.

4. net_margin: min 10%

   • Purpose: Require companies to earn at least a 10% net profit margin.
   • Rationale: Net margin measures how much profit a company keeps from each dollar of revenue. A minimum of 10%:
     • Screens out low-margin or barely profitable firms
     • Favors businesses with healthy profitability and pricing power
       For a general “what should I consider buying?” question, emphasizing financially solid, profitable companies is a prudent tilt.

5. quarter_revenue_yoy_growth: min 5%

   • Purpose: Ensure the company’s latest quarter revenue is growing at least 5% year-over-year.
   • Rationale: Revenue growth is a key indicator of business momentum. Requiring at least modest growth:
     • Avoids stagnating or shrinking businesses
     • Focuses on companies that are still expanding their top line
       This balances quality (profitability) with growth potential, which is attractive for long-term investors.

6. pe_ttm: min 10, max 30

   • Purpose: Filter for stocks trading at a “reasonable” valuation relative to earnings.
   • Rationale:
     • PE < 10 can sometimes indicate distressed, cyclical, or low-quality companies (though not always).
     • PE > 30 often reflects very high-growth or overhyped names where expectations may be fragile.
       By constraining the P/E to 10–30, the screen aims at:
     • Avoiding extreme value traps on the low end
     • Avoiding potentially overpriced growth on the high end
       This helps identify companies that are not obviously too cheap for a reason nor excessively expensive.

Why Results Match the User’s Question

• The user asked broadly what financial assets to consider buying. This screen interprets that as: “Which individual stocks might be sensible to look at?” and narrows to large, established U.S. companies.
• The filters collectively target stocks that are:
  • Relatively stable (low to moderate beta)
  • Well-established and liquid (S&P 500 components on major U.S. exchanges)
  • Profitable with solid margins (net margin ≥ 10%)
  • Still growing (revenue growth ≥ 5% YoY)
  • Reasonably valued (P/E between 10 and 30)

Together, this creates a list of higher-quality, moderate-risk, reasonably valued large-cap U.S. stocks, which is a sensible starting universe for someone asking what assets to consider buying, without drifting into very speculative or obscure names.
