Abstract
Liquidity plays an important role in global research. We identify high quality liquidity proxies based on low-frequency (daily) data, which provide 1,000X to 10,000X computational savings compared to computing high-frequency (intraday) liquidity measures. We find that: (1) Closing Percent Quoted Spread is the best monthly percent-cost proxy when available, (2) Amihud, Closing Percent Quoted Spread Impact, LOT Mixed Impact, High-Low Impact, and FHT Impact are tied as the best monthly cost-per-dollar-volume proxy, (3) the daily version of Closing Percent Quoted Spread is the best daily percent-cost proxy, and (4) the daily version of Amihud is the best daily cost-per-dollar-volume proxy.
