Risk and Opportunity Assessment

High trading volumes dampen short‑term volatility risk while offering a 0.2% spread advantage from algorithmic execution. Nevertheless, the concentration of liquidity providers could trigger price gaps if market depth narrows; diversified exposure remains essential.

Caner Yılmaz – BIST 100 Technical and Quantitative Analysis Director: "The strategic positioning of liquidity‑providing brokers preserves market depth, and the rise of algorithmic order flow mitigates short‑term price swings. Yet, the inherent concentration risk must not be overlooked; investors should reassess their liquidity risk profiles accordingly."
