Price Discovery Process

Korea Exchange has widen daily price limits from ±15% to ±30% of previous trading day’s closing price since June 15, 2015. In this paper, we examine how the event of widening price limits affect price discovery process over the course of trading day. In order to conduct this investigation, we compare price efficiency during such price discovery before and after the event. The changes that has occurred after the event can be summarized as follows: First, an analysis on full-sample indicates that price efficiency is maintained over the course of a trading, while it is aggravated temporary in two early intervals. Second, an analysis on sub-samples sorted by market capitalization, shares outstanding, or share price indicates that temporary aggravation of price efficiency in some mid-intervals is observed for shares outstanding lower group and share price top group. Overall, our results suggest that evidence supporting information hypothesis is found for the whole process of price discovery over the course of a trading day, though evidence supporting over-reaction hypothesis is found in some intervals or some types of stocks.

Price Discovery Process

This paper employs the multivariate VAR model to examine the mechanic work of price discovery process between sovereign CDS market and the associated sovereign bond market in contexts of five European and Asian countries, including Vietnam, Korea, Portugal, Italy and France from the beginning of 2008 to the end of April, 2017. The study accentuates on three aspects: the short-term interaction nexus between the sovereign CDS and the associated-sovereign bond market, the long-term co-movement between them and the discovery of which market plays the leading role in the pricing process. The results evidence the short-run and long-run relationship for the two markets. Particularly, the empirical test results support for the predominant role of the sovereign CDS market in the price discovery process in the bulk of sample entities. This might suggests for the governments to use CDS prices as the future indicator for predicting the volatility of debt markets.

Price Discovery Process

We investigate the relation between media coverage and the trading behavior of short sellers around earnings announcements. Prior research provides conflicting evidence on the role of the media, with some studies finding that the media can impede the price discovery process. Our evidence indicates that short sellers increase their activity in line with the tone of media coverage around earnings announcements, after controlling for earnings news and other factors that affect relative levels of short selling. Furthermore, we show that information in the media successfully forecasts earnings information in the days leading up to the earnings announcement, and that short sellers trade in a manner consistent with information reflected in media coverage preceding the earnings announcement. Our findings are consistent with information contained in the media having value relevance, and suggest that the media may help to facilitate the price discovery process around the release of earnings.
