Pre-audit showing the fixed basket has 27 verifiable common stocks, too few for the monthly top-100 universe, so data_hold.

A historical record, not rerun in this migration.

The figures, hypotheses and verdicts of the time are preserved. A past positive result or candidate mention does not mean validated profitability today or a live-trading recommendation. Validation periods that were already used are not treated as new independent validation.

This is an English translation of a preserved Korean original. It describes conditions at the time of writing, not current provider specifications, costs or regulations.

EXP-015 universe pre-audit

  • Status: data_hold

| generated_at | 2026-09-17T00:00:00+09:00 |

  • Daily-bar symbol directory in the current CREON snapshot: 3552
  • EXP-011 fixed basket: 30 names; common stocks verifiable after excluding known ETFs and preferred shares: 27
  • Contract requirement: a monthly top-100 liquidity universe; halt new entries if fewer than 50 in a month
  • The current fixed basket alone cannot reproduce the top-100 and 50-name minimum requirements.
  • The full snapshot is the current listing, with no point-in-time listing/delisting master or product classification. Producing EXP-015 performance from the 30-name basket without filling this gap would be a different experiment from the design.

Conclusion: strategy account execution is put on hold. The next start condition is a point-in-time common-stock classification and a month-end 60-day trading-value ledger.
