Security Selection and Market Universe

Investable-universe, marketable-security, security-classification, and selection-screen terms used before portfolio construction.

Security Selection and Market Universe terms help classify the securities, issuers, vehicles, rights, liquidity profiles, and accounting labels that define an investable universe.

Use this branch when the investable set, ownership right, fair-value input, cash-equivalent status, issuer signal, or cross-border vehicle affects portfolio selection.

What to Check

Check the security type, issuer, listing or trading venue, liquidity, rights, transfer restrictions, fair-value level, accounting classification, and whether the label affects portfolio eligibility.

Common Mistakes

  • Treating eligibility or accounting classification as investment merit.
  • Ignoring liquidity, transfer restrictions, ownership rights, and valuation inputs.
  • Comparing securities from different markets without checking currency and settlement.
  • Using a broad market-universe label without defining what is included and excluded.
