Idiosyncratic risk and foreign investors : Empirical evidence from the Korean stock market
Junho Hwang 한국재무학회 2019 한국재무학회 학술대회 Vol.2019 No.11
This paper examines the effect of foreign ownership on idiosyncratic risk of individual stock in Korean stock market. We find that foreign ownership is negatively related to idiosyncratic risk. This result is robust to multiple idiosyncratic risk measures and regression methods. We find two underlying channels through which foreign ownership reduces the idiosyncratic risk: through influencing price informativeness and enhancing monitoring effect. Our results support that foreign investors reduce the idiosyncratic risk by enhancing monitoring, while the informativeness channel has weaker explanatory power.

The authors derived the criteria on the process parameters of laser depositions with metal powers(SUS316L & IN718) by evaluating the surface and cross-section properties of the deposition layers. The surface characteristics of the deposition layer are investigated through optical microscopy by controlling the process parameters of laser output, powder feeding rate and gas feeding rate. The cross-section characteristics were also analyzed after polishing and chemical etching process. As the gas feeding rate increased, the amount of powder loss increased and the difference in the dilution ratio and heat affected zone depending on laser outputs was observed. In addition, the powder feeding rate used in the experiment did not interfere with the energy absorption of the base material.
