- Petkim shares were moved temporarily from continuous trading to a single-price call auction.
- The intervention followed an equity-based circuit breaker and was described as operational rather than fundamental.
- Petkim's planned petrochemical expansion remains subject to a final investment decision.
Petkim shares were temporarily moved from continuous trading to a single-price call auction on Friday, October 30, after an equity-based circuit breaker was triggered. TipRanks reported that order collection and matching were to continue under auction conditions before normal trading was scheduled to resume at 17:15:45.
Temporary Halt Limits Price Discovery
The circuit breaker is an exchange mechanism designed to interrupt continuous trading when predefined volatility thresholds are reached. The temporary auction can slow short-term price discovery and affect liquidity, but the event itself does not establish a change in Petkim's operating outlook.
Petkim operates in the petrochemical industry and produces chemical products used in plastics, textiles and other industrial applications. Its shares trade on the local equity market under the PETKM ticker and remain exposed to the trading rules and volatility controls of that market.
Expansion Still Awaits Investment Decision
Petkim is also progressing with a planned polyethylene production complex in Aliaga-Izmir. The project is expected to add 850,000 metric tons of annual capacity through two production lines, while the final investment decision remains pending.
