نوسانات بازار و بازده سهام: نقش تأمین کنندگان نقدینگی

This study shows that market volatility affects stock returns both directly and indirectly through its impact on liquidity provision. The negative relation between market volatility and stock returns arises not only from greater risk premiums but also greater illiquidity premiums that are associated with higher market volatility. Consistent with our expectation, we also find that stock returns are more sensitive to volatility shocks in the high-frequency trading era, and after the regulatory changes in the U.S. markets that increased competition between public traders and market makers, reduced the tick size, and decreased the role of market makers.
