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

Developments Continue in Borsa Istanbul

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

Implemented Measures and Their Effects

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

During the same period, an order package measure will be applied to Burçelik (BURCE.E) and Oyak Investment Trust (OYAYO.E) stocks. This measure includes restrictions on the entry of market orders and limit orders, a ban on order cancellations and quantity reductions, and the limitation of order aggregation information dissemination during the trading of these stocks.

Market Reflections

Such measures are generally used to reduce market volatility risk and ensure investor safety. The taken precautions may prompt investors to revisit their risk management strategies. The restrictions on short selling and margin trading will particularly pose a significant barrier for investors with short-term trading strategies.

Conclusion

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