Abstract:
This thesis examines liquidity commonality in the Stock Exchange of Thailand (SET) during 2003 to 2013 in respect of supply-side (funding liquidity of financial intermediaries) and demand-side (correlated trading of market participants) determinants of liquidity. Unique asymmetric pattern is found, where the commonality greater increases during large market rising than during large market declining period. The result shows more reliable evidence of demand-side hypothesis. Investor-types’ trading activities affect differently to the commonality in liquidity of each stock-size. For instance, retail and foreign investor trading are found to create greater liquidity commonality during high volatility period, while proprietary trading has the opposite effect. On average, large-cap stocks have higher commonality in liquidity, but small-cap stocks have greater commonality risk from correlated trading activity of particular investor-type.
