dc.description.abstract | Justifying intraday trading rate as the proportion of trades by whom a person buy and sell
the same stock in a day, the Korea Stock Exchange market recorded the highest level last two years (2000 and 2001). So we can doubt about its harmful influence as an angle of volatility and destabilization and market inefficiency. I have used two ways of approaches to test it. One is intraday trading volume to total trading volume ratio of every stocks of Korean stock market approach as a cross-sectional analysis, the other is vector-auto regression approach as a time-series analysis. As the cross-sectional analysis, I have tested six suspicious problems in relation to intraday tradings. First, I found that a portfolio with higher rate of intraday trading has recorded significantly higher intraday volatilities. But this fact doesnt mean intraday tradings make the stock market more riskier, because intraday trader gathered on the stock which has high intraday volatility. Second, I have tested if intraday traders have a habitude of flocking together on the high idiosyncratic risk stocks or not. And intraday tradings distorted price formation patterns. As for the time-series analysis, I have tested with VAR method whether intraday tradings make Korean stock market more volatile. I couldnt find any reasonable evidence of it. I have tested it with daily trading volume data of KOSPI index. Because the index is aggregated data and it couldnt figure out the nature of intraday tradings. These results support the opinion of ristrictionist that intraday trading hasnt made market more inefficiently in the cross-sectional approach and the time series approach. | - |
