TEK HİSSE SENEDİ VADELİ İŞLEMLERİ VE SPOT VOLATİLİTE: BORSA İSTANBUL'DA BİR OLAY ARAŞTIRMASI

Özet

This study investigates the impact of the introduction of Single-Stock Futures (SSFs) on stock volatility and trading volume in Türkiye's Borsa Istanbul. Utilizing an event study methodology with the Exponential Generalized Autoregressive Conditional Heteroskedasticity (EGARCH) model, it examines 43 stocks listed on Borsa Istanbul with corresponding futures contracts on the VIOP exchange. The results show that introducing SSFs correlates with increased market volatility and trading activity, challenging the traditional market stability theory associated with derivatives. This study contributes significantly to the literature on financial derivatives in emerging markets, highlighting the dynamics and implications of SSFs on underlying stock behavior, and provides insights for investors, fund managers, and policymakers in assessing the impact of derivative trading on market dynamics.
