Several Asia-Pacific financial markets impose price limits to reduce excessive fluctuations. We examine stock price behavior following daily limit moves on the Shanghai Stock Exchange for 200 firms in the period 1997–2004. We find weak evidence for the occurrence of overreaction on the Shanghai stock market on the basis of price limits. We conclude that investors do not exhibit overreaction to the event of limit activation except in the case of 1-day up limit moves. We also conclude that the Shanghai Stock Exchange can be regarded as a (semistrong) efficient market.

The effects of price limits and market illiquidity are crucial for pricing derivatives based on some underlying assets traded in the markets with a price limit rule and an illiquidity phenomenon. We develop models to value options for the cases of either the underlying assets encountering price limits and market illiquidity, or when the underlying assets are imposed with price limits and the options themselves show market illiquidity in this paper. The Black–Scholes (1973) model, the Krakovsky (1999) model, and the Ban, Choi, and Ku (2000) model are presented as special cases of our model. Our numerical results show that both the price limit and market illiquidity significantly affect the option values.

The purpose of this study is to examine how the volatility interruption (VI) mechanisms affect idiosyncratic volatilities in Korean stock markets.

Collecting the South Korea Stock Market (KOSPI) data from June 15, 2015 to March 31, 2019, we collect each residual,  εi,t, from three different estimated models: capital asset pricing model (CAPM), FF3 and FF5. To estimate the conditional idiosyncratic volatility, the authors employ two conditional time-varying measurements: GARCH and TGARCH.

The results show that the conditional idiosyncratic volatility increases when stock prices reach the upper and lower static limits, indicating the implementation of adopting static VI mechanism neither stabilize market conditions nor reduce excess volatility along with the existence of price limits.

Although market regulators and policymakers improve market conditions with the advanced VI mechanism, the empirical results show the adverse effect of the mechanism. Not allowing investors to earn above average returns without accepting above average risks makes Korean stock markets inefficient along with advanced VI mechanisms.

The purpose of this paper is to explore how the price limit policy implemented in 2014 affects initial public offering (IPO) underpricing and long-term performance in China.

The data are the IPOs from Shanghai Stock Exchange (SSE) and Shenzhen Stock Exchange (SZSE) between 2004 and 2018. The data are firstly divided into the IPOs before the price limit policy and the IPOs after the price limit policy according to the time of issuance. Then the two groups are divided into 4 subsamples according to the market blocks and the P/E ratio. The authors use multiple regression models to explore the effect of price limit policy in each subsample.

The first-day price limit system for IPOs is similar to the upward fuse mechanism, the purpose of which is to suppress IPO underpricing. However, this study finds that the policy does not suppress IPO underpricing, but increases the underpricing rate in all subsamples. Besides, the long-term performance in each subsample is different from each other. Main Board stocks’ long-term performance is worse after the policy. The policy makes Small and Medium Enterprise Board (SME Board) and Growth Enterprise Market Board (GEM Board) stocks with high P/E ratios perform better in the long term. For SME Board and GEM Board stocks with low P/E ratios, the policy makes no significant effect.

Good policy intentions may sometimes lead to counterproductive effects. However, since the long-term performance of each subsample is different, it is difficult to judge whether the policy should continue to be implemented or cancelled. Implementing different policies for different subsamples may be a better way to solve this problem.

This paper contributes to the study of IPO underpricing and long-term performance from the perspective of price limit policy.

This paper aims to analyze the impact of price-limit hits by hit type and when such hits start and stop using intraday trades and quotes at a one-second frequency for firms included in the BIST-50 index during the 13-months starting with March 2008. Like the recent COVID-19 period, this period includes the heightened stress in global financial markets in September 2008.

Using intra-day trades and quotes at a one-second frequency, the authors examine the market effects of price limits for firms included in the BIST-50 index during the global financial crisis. The authors compare the values of various metrics for 60 min centered on price-limit hit periods. The authors conduct robustness tests using auto regressive integrated moving average (ARIMA) models with trade-by-trade and with 3-min returns.

The findings are supportive of the following hypotheses: magnet price effects, greater informational asymmetric effects of market quality and each version of price discovery. Results are robust using samples differentiated by cross-listed status, same-day quotes instead of transaction prices and equidistant and trade-by-trade returns.

The authors use intraday data to reduce measurement error that is particularly pronounced when daily data are used to assess price limits that start and/or stop during a trading session. The authors contribute to the micro-structure literature by using ARIMA models with trade-by-trade and 3-min returns to alleviate some bias due to the autocorrelations in returns around price-limit hits in the presence of a magnet effect. The authors include some recent regulation changes in various countries to illustrate the importance of circuit breakers using price limits during COVID-19.

The purpose of this paper is to re-examine the effectiveness of price limits on stock volatilities in China over a more recent time period spanning from 2007 to 2012. The motivation stems from the fact that very high stock market volatilities are observed in China and we are sceptical of the volatility mitigating effect claimed by advocates of price limits.

The effectiveness of price limits on volatilities is examined using an event study methodology and within an expanded framework of volatility-volume relationships. The sample stocks include the 300 component stocks of the CSI300 Index.

Both event study and regression analysis suggest that price limits exaggerate market volatilities by causing volatility spillovers. The destabilising effect is much more pronounced for small firm stocks and when the market falls. In addition to the informational source of volatilities (represented by volume), price limits create another non-trivial frictional source of volatilities in China’s stock market.

This research is the first to re-examine the price limit effect in China’s stock market in an expanded framework of volatility-volume relationships. It identifies price limits, in addition to information, as another non-trivial frictional source of volatilities. The findings derived from a recent sample period confirm the conventional view of inefficiency of price limits raised by Fama (1989) and provide evidence in support of the pervasive trend of stock market deregulations.

The purpose of this paper is to take advantage of a natural experiment in Taiwan to test the effect of short‐sales constraints on price dynamics.

Since September 1998, short‐selling is banned at a price below the close price of the previous trading day. The new rule creates unique daily dynamics of short‐sales constraints. The paper employs a difference‐in‐difference method to evaluate whether the short‐sales constraint rule plays an important role in the price dynamics.

The results show that stock prices react to information in a way similar to if short‐selling was not banned. This is in line with the implication of a rational expectation framework like Diamond and Verrecchia.

The paper has implications on the short selling bans in the 2008/2009 credit crisis and the European debt crisis because the bans are public information as those in this setting. The rational agents in the market could incorporate the bans into price beliefs which could lead to the ineffectiveness of the policy. The short‐sales constraints may be widely imposed in the crisis but they are not the effective tools to alleviate downward price pressures.

The results suggest that the effort of the government to boost stock price by imposing short sales constraints will not be effective if rational investors take the constraints into account while forming their beliefs.

Unlike existing short‐sales constraint proxies like short interest or lending fees, the dynamic constraints do not suffer from endogeneity. Moreover, the constraints are public information and thus ideal for testing the rational expectation models, in which investors have to be aware of the level of the constraints.

This paper seeks to provide a detailed study of the impact of offers incorporating a time‐limit restriction on consumers in the context of price promotions. Time limited offers are those where a pricing offer is only available for a specified, normally relatively short, period of time. Although price promotions have been the subject of much previous research, a detailed study of the effects of time limit restrictions on consumer behavior is warranted.

The study incorporates an experimental approach whereby the impact of time‐limited and non time‐limited offers on consumers' assessments of value and search and purchase intentions are isolated.

Findings show that the presence of a time limit does not impact directly on perceptions of value or search and purchase behavior. A marginally significant interaction effect between time limit and discount size is present, impacting in particular on search behavior.

The research was carried out in the context of a consumer durable good (TV) and it is recommended that the study is replicated in other contexts, such as services and packaged goods, to ensure that the results reported here are generalisable.

The results suggest that policy makers should not assign significant time and resources to investigating influences of alleged false time limit promotion, as the findings would lead to the conclusion that such resources would be better used controlling other forms of misleading advertising and promotion. Marketing managers should note that time limited offers have no significant impact on consumer perceptions or purchase intentions.

The paper is of value to both the policy making community and practitioners and provides important and original insights into the minimal impact of time limit restrictions on consumers' evaluation of price promotion offers and subsequent behavioral intentions.

Despite regulatory claims of straitening volatility and preventing crashes, evidences on circuit breakers' ability to achieve so are nonconclusive. While previous scholars studies general performances of circuit breakers, the authors examine whether Malaysian price limits aggravate volatility, impede price discovery, and interfere with trading activities in both tranquil and stressful periods.

The study uses a combination of parametric and nonparametric techniques consistent with Kim and Rhee (1997) to examine the major ex-post hypotheses in circuit breaker research.

For calm markets, the authors find significant success of upper limits in tempering volatility with low trading interference. Lower limits show mixed results. Conversely, in crisis markets limits fare poorly in nearly all aspects, particularly for lower limits.

Ramifications of the paper's findings are discussed through highlighting the asymmetric nature of price limits' ex-post effects. The paper also contributes to regulatory debate surrounding the quest for an optimal price limit.

The paper is the first of its kind in documenting long-horizon evidence of ex-post effects of a wide-band price limit. Moreover, the paper is unique in its approach in bifurcating circuit breaker performance along the line of market stability periods.

Magnet effect entails a hypothesis in market microstructure entailing a systemic likelihood of prices being sucked toward the theoretical threshold. The purpose of this paper is to investigate the existence of magnet effect in Bursa Malaysia via overnight returns.

This study investigates the existence of magnet effect via overnight returns in Bursa Malaysia by utilizing historical daily price data from 1994 to 2017 by probabilistic regression approaches. The authors divide the study period into three distinct regimes based on regulatory limit mechanisms.

Based on demarcated regimes, the authors find evidence of magnet effect in Bursa Malaysia throughout all regimes, with a heightened magnitude detected between 2002 and 2013. Moreover, upper limit scenarios exhibit a greater propensity for magnet effect. The authors end the paper with implications of the findings for portfolio managers, intraday traders, and policymakers.

The research is the first of its kind in attempting to measure the magnet effect in Malaysia via overnight jumps.
