Abstract

Trading of KOSPI200 options on Eurex launched in 2010 starts at 17:00 after market and closes at 05:00 in the next morning. This paper attempts to examine the role of put-call ratio of KOSPI200 nighttime options in price discovery process of spot market. The main findings of this paper are summarized as followings; The information content of put-call ratio of nighttime options is significantly incorporated in opening price of spot market next trading day but not delayed to the daytime spot market. Specifically, all put-call ratios measured in terms of total volume, total value, and cleared volume of nighttime options has strongly positive correlation with returns of KOSPI200 next trading day but put-call ratio of daytime option market has no predictive power of next daily return during sample period. This implies that the nighttime options market shows more leading role than daytime options in opening price discovery. This relationship between put-call ration and spot market return remains statistically significant during the period of the multiplier for KOSPI200 options increased. However, the change in put-call ratio of nighttime options is significantly explained by precedent put-call ratio of daytime market. This Overall empirical evidence indicates that traders of KOSPI200 options have tendency to implement strategy of linkage between price movement of daytime and nighttime market.

Abstract

The National Pension Service (NPS) of Korea is one of the largest institutional investors in the world and it has been known as the market stabilizer in the Korean stock market. Nevertheless, it is hard to find the research about the impact of the NPS on the futures market. We investigated the effect of the NPS’s trading KOSPI200 futures on the returns, the liquidity and the volatility of the market using the recent ten years’ transaction data. The main findings are as follows. First, the NPS’s net investment flow (NIF) in the KOSPI200 futures market shows the predictability about the returns of both KOSPI200 futures and KOSPI200 spot index. Second, the NPS’s NIF in the KOSPI200 futures market improves the liquidity of the KOSPI market, where the transactions involved in both the spot market and the futures market occur. Third, the NPS’s NIF in the KOSPI200 futures market reduces the volatility of both the KOSPI200 futures market and the KOSPI market. Unlike the prior studies showing that our futures market tends to increase the volatility of the stock market through the volatility transfer, our finding suggests that the NPS’s trading KOSPI200 futures contributes to decreasing the volatility in both markets. To the best of the authors’ knowledge, this paper is the first study that investigates the impact of the NPS’s trading KOSPI200 futures on the KOSPI200 futures market and the stock market. It shows that the NPS plays a role of the market stabilizer in the futures market. In addition, the NPS’s trading KOSPI200 futures also affects the KOSPI stock market, stabilizing it in terms of both the liquidity and the volatility.

Abstract

It is known that the National Pension Service (NPS) of Korea contributes to the market stability because it tends to pursue the negative feedback trading strategy in the Korean stock market. While many studies deal with institutional investors’ trading in the financial derivatives market, the NPS’s trading in the derivatives market is rarely studied. Using the NPS’s trading data for the period from January 2010 to March, 2020, the authors examine the transactions of the NPS in the KOSPI200 futures market. We find that the NPS’s net investment flow (NIF) in KOSPI200 futures is negatively associated with the past returns of KOSPI200 futures and the KOPI200 index. However, we also find that the NPS’s NIF of KOSPI200 futures is positively associated with its NIF in KOSPI200 stocks. Along with the legal restriction on the NPS’s trading in the derivatives market, the result suggests that the NPS uses KOSPI200 futures to deviate the problems related to non-synchronous trading in the spot market. To the best of our knowledge, this paper is the first study of the NPS’s transactions of KOSPI200 futures. The paper suggests that the NPS does not trade KOSPI200 futures for hedging or arbitrage profit but for complementing its transactions in the spot market of KOSPI200 stocks.

Abstract

This study explores the Granger causal relationship between return and volume in the KOSPI200 spot and option markets for the period from December 13. 2002 to December 9. 2004. using minute-by-minute data. Specifically, we examine the lead-lag relationship among OPtion volume, option return, cash volume, and cash return to determine whether option volume and return impact cash return.

Our results show that option volume has no direct impact on cash return as cash return unilaterally leads option volume‘ While option volume impacts cash volume. cash return unilaterally leads cash volume. implying no indirect impact of option volume on cash return.

However, there is evidence that option return impacts cash return directly, given a bilateral causality between option return and casll return. Option return also impacts cash volume, but again cash volume has no impact on cash return. meaning no indirect impact of option return on cash return. Our findings were generally robust across days of the week and different maturities. Finally, we analyzed lead-lag relationship within the option market. and found a bilateral causality between option volume and option return. This implies that option volume may impact cash return indirectly via option return.

Abstract

Purpose

This paper aims to provide the necessity to activate long-term exchange-traded derivatives (ETD) in Korea. In the era of aging, low interest rates and low economic growth, the investment demand for long-term financial products, and its hedging demand have steadily increased. Unfortunately, long-term ETD do not trade in Korea, and this study presents political suggestions to invigorate long-term ETD based on overseas cases and empirical analysis. Specifically, this study suggests the necessity to activate exchange traded funds (ETFs) options, long-term Korea treasury bond futures and options and long-term Volatility Index of Korea Composite Stock Price Index future and options. The introduction of those long-term ETD not only contributes to providing long-term investment and hedging vehicles but also reduces market inefficiencies in the Korean industry of ETFs, bonds and structured products.

Abstract

The KOSPI200 mini options market, introduced in July 2015, is a market where the trading multiplier is reduced to one-fifth of the regular options. This study shows that the price discovery effect of the original options and the mini options estimated by the vector error correction model (VECM) and Hasbrouck's information share (1995, 2003), based on the regular options-mini options arbitrage and the options-spot arbitrage. The results of the empirical analysis are summarized as follows. First, in the price discovery between the regular options and the mini options, regular options dominate mini options at a statistically significant level. Second, mini options tend to lead the spot, which is stronger than the regular options. Therefore, the regular options and the mini options show asymmetrical behavior in the price discovery process of the spot, opposite to each other and are interpreted as alternative derivatives in terms of investment strategy. Considering the immaturity of mini options market established during the sample period, the price discovery is efficient even though the trading activity in the mini options is lower than that of the regular options.

Abstract

This study investigates the deviation from put-call parity in the KOSPI200 options market. The sample period is from January 2, 2006 to May 31, 2009. Due to the financial crisis in 2008, short sale of stocks had been prohibited from October 1, 2008 to May 31, 2009. The sample is divided into the pre-crisis period and the crisis period. The crisis period is the period during which short sale of stocks are prohibited. The summary statistics shows that the trading volume of KOSPI200 stocks doubled, but the trading volume of call options and that of put options declined to one half and one third from the pre-crisis period to the crisis period, respectively. The equation which relates the deviation of futures price to the deviation of put-call parity is derived and the deviation from put-call parity is analyzed by using two stage least square. This paper looks into not only the prior 60 day return's momentum effect, but also the intraday spot return's momentum effect. Evidence indicates that the intraday momentum does exist in options and stock prices. Empirical results show that the prior 60 day return's momentum effect is statistically insignificant during the pre-crisis period, but statistically significant during the crisis period whereas the intraday return's momentum effect is strongly significant for both of the periods. This result lends support to the argument that the deviation of futures price from its theoretical price is a component of the deviation from put-call parity. The sign and significance of the regression coefficient for momentum effects are consistent with Kim and Park (2011) and Kim (2012) again lending support to the validity of their regression equation. Overall, our results are consistent with the validity of the derived equation, Kim and Park (2011) and Kim (2013)’s rationale.

Abstract

This paper investigates a retrospective on the Journal of Derivatives and Quantitative Studies (JDQS) on its 30th anniversary based on bibliometric. JDQSs yearly publications, citations, impact factors, and centrality indices grew up in early 2010s, and diminished in 2020. Keyword network analysis reveals the JDQS's main keywords including behavioral finance, implied volatility, information asymmetry, price discovery, KOSPI200 futures, volatility, and KOSPI200 options. Citations of JDQS articles are mainly driven by article age, demeaned age squared, conference, nonacademic authors and language. In comparison between number of views and downloads for JDQS articles, we find that recent changes in publisher and editorial and publishing policies have increased visibility of JDQS.

Abstract

Informed traders may prefer the options market to the stock market for reasons including the leverage effect, transaction costs, restrictions on short sale. Many studies try to predict future returns of stocks using informed traders' behavior in the options market. In this study, we examine whether the trading volume ratios of single stock options have the predictive power for future returns of the underlying stock. By analyzing the stock price responses to the “preliminary announcement of performance” of 36 underlying stocks on the Korea Exchange from November 2014 to March 2021 and the trading volume of options written on those stocks, we investigate the relation between the option ratios, which are the call option volume to put option volume ratio (C/P ratio) and the option volume to stock volume ratio (O/S ratio), and the future returns of the underlying stock. We also examine which ratio is better in predicting the future returns. The authors found that both option ratios showed the statistically significant predictability about future returns of the underlying stock and that the return predictability of the O/S ratio is more robust than that of the C/P ratio. This study shows that indicators generated in the options market can be used to predict future underlying stock returns. Further, the findings of this study contributed to a dearth of literature pertaining to single stock options. The results suggest that the single stock options market is efficient and influences the price discovery in the stock market.

Abstract

Purpose

Amid benign monetary policy in mature market countries and high liquidity‐induced demand, lower risk premia have encouraged risk diversification into alternative asset classes outside the scope of conventional investment. The development of derivative markets in emerging economies plays a special role in this context as more institutional money is managed on a global mandate, with more and more capital being dedicated to emerging market equity. This paper aims to focus on these issues.

Design/methodology/approach

This paper reviews the recent development of equity derivative markets in emerging Asia and informs a critical debate about market practices and prudential supervision. Goal of the paper is also to outline essential elements and key policy considerations in developing derivative markets.

Findings

The supervision of emerging derivative markets depends on the expedient and tractable resolution of challenges arising from consistent risk management, risk mutualization, and prudential standards that guarantee market stability in crisis situations. In particular, further efforts are needed in areas of cash market liquidity, trading infrastructure as well as legal and regulatory frameworks based on a set of coherent principles for capital market development.

Originality/value

The paper offers a comprehensive set of principles for the development of equity derivative markets based on the current state of equity derivative trading in emerging Asia. Given current efforts by national regulators in the region to implement comprehensive guidelines on derivatives and revise short selling restrictions, the scope of this paper has topical appeal from the perspective of market participants and regulators.
