Turkey introduces ‘uptick rule’ for short selling following sharp stock market decline

Turkish market authorities have introduced the so-called " uptick rule" for short selling in the stock market.

This measure comes as a direct response to Turkey' s primary stock exchange index, the BIST 100, falling by more than two percent during the trading session.

The regulation is intended to help stabilise the market and will apply to all short sale transactions executed in the stock market for the remainder of the current trading session.

The decision highlights the authorities' rapid response to managing periods of increased volatility. The " uptick rule" is a mechanism that typically requires a short sale to be executed at a price higher than the previous trade, or at least at the last traded price if that price was an uptick.

The primary purpose of this rule is to limit aggressive short selling, which can amplify declines in share prices during falling markets.

By activating this rule, Turkish market regulators aim to dampen downward pressure on share prices.

This is particularly important when key indices show significant declines, as is the case with the BIST 100 index, which has surpassed a two percent drop. For investors and participants in the Turkish stock market, this means that short selling strategies will be temporarily restricted.

The measure signals the authorities' willingness to intervene to protect market stability and potentially prevent further uncertainty or speculative selling that could undermine investor confidence.
