The Joint Dynamics of Liquidity, Returns, and Volatility Across Small and Large Firms Book uri icon

abstract

  • This paper explores liquidity spillovers in market-capitalization based portfolios of NYSE stocks. Return, volatility, and liquidity dynamics across the small and large cap sector are modeled by way of a vector autoregression model, using data that spans more than 3000 trading days. We find that volatility and liquidity innovations in either sector are informative in predicting liquidity shifts in the other. Impulse responses indicate the existence of persistent liquidity, return, and volatility spillovers across the large and small cap sectors. Lead and lag patterns across small and large cap stocks are stronger when spreads in the large cap sector are wider. Consistent with the notion that private informational trading in large cap stocks is transmitted to other stocks with a lag, order flows in large cap stocks decile significantly predict both transaction price-based and mid-quote returns of small cap deciles when large-cap spreads are high.
