Borsa Istanbul's Short Selling Decision: Upward Tick Rule to Be Applied

Borsa Istanbul has decided to implement the upward tick rule for BIST 50 stocks that can be short sold, starting from September 22 until further notice. This regulation requires short selling transactions to be executed at a price higher than the last traded price. The upward tick rule mandates that investors who want to short sell must bid above the last transaction price. Thus, short selling transactions cannot be carried out below the current market price. This decision aims to regulate short selling activities in BIST 50 stocks. The implementation will take effect from September 22 and will continue until a new announcement is made. Not investment advice.

Borsa Istanbul's decision to implement the uptick rule for short selling could limit speculative selling pressure in the short term and reduce volatility. However, such regulations generally reduce market liquidity and weaken price discovery, resulting in a neutral effect. Technical indicators are mixed: RSI is flat around 50, MACD is in negative territory but above the signal line, and the price is slightly above the SMA20 but below the SMA50. The limited 0.4% rise in the last 24 hours and weak momentum do not provide a clear directional signal. The news impact may be limited; the 1-3 day outlook is neutral.

📊 GARAN — Piyasa Yorumu

■ neutral · 55%

Borsa Istanbul's implementation of the uptick rule for short selling could limit speculative selling pressure in the short term and reduce volatility. For GARAN, this regulation is not a direct catalyst; however, the current technical outlook is already positive (RSI 62.6, MACD above signal, price above SMA20 and SMA50). Despite the 2.46% rise in the last 24 hours, RSI is approaching overbought territory, increasing the risk of a short-term pause or limited pullback. The news impact could be neutral to positive; the main direction will be determined by additional news flow regarding the banking sector and the overall index outlook. In the 1-3 day period, a sideways-volatile course is likely, with a higher probability of an upward attempt if the price sustains above 133.1.

📊 AKBNK — Piyasa Yorumu

■ neutral · 60%

The implementation of the uptick rule for short selling may contribute to price stability by reducing speculative selling pressure in the short term. However, AKBNK stock has already risen 2.48% in the last 24 hours and its RSI is at 64, approaching overbought territory. MACD is positive and the price is above SMA20 and SMA50, indicating a positive technical outlook. The impact of the news may be limited; market-wide short selling restrictions may not create stock-specific demand. I expect a neutral course in the short term, and the additional buying signal for the continuation of the current trend is weak.
