Important Measures on 4 Stocks from BIST: Short Selling and Order Restrictions

Developments Continue in Borsa İstanbul

Borsa İstanbul has decided to implement preventive measures for 4 stocks in its recent assessments aimed at increasing market security. This move is considered an important development not only in attracting investors' attention but also for the overall health of the market.

Implemented Measures and Their Effects

Within the framework of the Volatility-Based Measure System (VBTS), the shares of AHES GYO (AHSGY.E) and İmaş Makina (IMASM.E) have been closed to short selling and margin trading from the transactions dated November 10, 2025, until December 9, 2025. This situation aims to restrict investors' opportunities for speculative trades on these stocks.

At the same time, Burçelik (BURCE.E) and Oyak Yatırım Ortaklığı (OYAYO.E) will be subject to order package measures. This measure includes restrictions on the entry of market orders and limit orders during the trading of these stocks, banning order cancellations and quantity reductions, and limiting the publication of order aggregation information.

Market Reactions

Such measures are generally used to reduce the risk of market fluctuation and to ensure investor safety. The precautions taken may cause investors to reconsider their risk management strategies. The restrictions on short selling and margin trading will pose a significant obstacle, especially for investors with short-term trading strategies.

Conclusion

The measures implemented by Borsa İstanbul may lead to significant changes in the liquidity of stocks and investor behavior. It is crucial for investors to closely monitor these developments and make their investment decisions accordingly.
