The pattern of intra-day stock price volatility is established in the academic literature as having a U-shape, with heightened volatility at the open and at the close compared to the other periods of the trading day. We establish in this study that there are variations in this pattern across different days of the week. More precisely, we see that the intra-day U-shaped pattern is more accentuated when we take into consideration the day of the week. Using intra-day data from the New York Stock Exchange, London Stock Exchange, Deutsche Boerse and Euronext Paris stock markets we show that Monday openings are consistently more volatile than opening periods of other days, and similarly Friday closings are consistently more volatile than closing periods of other days. These findings indicate the increased difficulty of price discovery just before and after the weekend non-trading period. Variance-ratio statistics are employed to test for the significance of our findings.

This paper examines the stock price behavior around the ex-split dates both before and after the decimalization on the New York Stock Exchange (NYSE). We find that the abnormal ex-split day returns decrease and the abnormal trading volume increases in the 1/16th and decimal pricing eras, relative to the 1/8th pricing era. These findings are consistent with the microstructure-based explanations for the ex-day price movements. Our study also supports the hypothesis that short-term traders perform arbitrage activities during the ex-split dates when transaction costs become lower after the tick size is reduced.

This paper studies the degree of impact of stock prices listed on the New York Stock Exchange and Tokyo Stock Exchange regarding price behavior in Asian stock markets. Our evidence shows that the pattern and magnitude of impact varies. Returns in Hong Kong, Singapore, and Malaysia are more sensitive than those in Taiwan, Korea and Thailand. The response patterns in the Asian markets suggest that foreign influence is significantly correlated to the degree of market openness.

Opening And Closing

This paper examines opening and closing return patterns on the Chinese stock markets. We find that open-to-open returns are significantly more volatile than close-to-close returns. In addition, the correlation of the overnight return with the following daytime return is significantly negative, while the correlation of the daytime return with the following overnight return is strongly positive. The results show strong price continuation around the close and strong price reversal at the open, and the findings are not sensitive to trading volume. The findings are less likely to be caused by price limits. Our results are inconsistent with previous findings from the Tokyo Stock Exchange, yet similar to those from the New York Stock Exchange, albeit under a different market structure.

Hourly Basis

Contemporary business continues to intensify its radical relation to time. The New York Stock Exchange recently announced that in pursuing (as traders call it) the ‘race to zero’ they will begin using laser technology originally developed for military communications to send information about trades nearly at the speed of light. This is just one example of short-term temporal rhythms embedded in the practices of contemporary firms which watch their stock price on an hourly basis, report their earnings quarterly, and dissolve future consequences and costs through discounting procedures. There is reason to believe that these radical conceptions of time and its passing impair the ability of businesses to function in a morally coherent manner. In the spirit of other recent critiques of modern temporality such as David Couzen Hoys The Time of Our Lives, in this paper, I present a critique of the temporality of modern business. In response, I assess the recent attempt to provide an alternative account of temporality using theological concepts by Giorgio Agamben. I argue that Agamben’s more integrative account of messianic time provides a richer ambitemporal account which might provide a viable temporality for a new sustainable economic future.

The Individual

Trading friction leads into accentuated stock price volatility over the short term. As such, short-term accentuated volatility can be viewed as symptomatic of a market with increased inefficiencies in the price discovery process. If price discovery is marked by price swings, runs and reversals, then short period (intra-day) volatility is heightened in that market. In this study, we use return series with various differencing intervals that are as short as half-hour and as long as two weeks to investigate the short-term volatility accentuation in five different equity markets: the Nasdaq Stock Market and the New York Stock Exchange in the US, and the London Stock Exchange, Deutsche Boerse and Euronext Paris in Europe. In all these markets, we investigate the individual stocks that make up a major index during the calendar year 2000. Variance-ratio statistics are employed to investigate the quality of these five markets. Results confirm an intra-day reverse J-shaped pattern of half-hour volatility in these markets. The evidence also suggests an accentuation of volatility during longer periods, such as 24-hour intervals. This accentuation appears to subside when we extend our differencing interval to longer periods such as one-week or two-week returns.

Dual Listing

Various studies have been carried out in relation to the behavior of dual listing stock prices, unfortunately, study on the effects of changes in dual listing stock prices on the Indonesia Stock Exchange (IDX) is still limited. Differences in trading time and stock exchange class between one stock exchange with another in different countries raise an opportunity for the accumulation of information when one of the exchanges is experiencing a closing trading period. Indonesian companies such as PT. Telekomunikasi Indonesia (Persero) Tbk. (TLKM) whose shares are listed on the New York Stock Exchange (NYSE) and IDX experience the difference in time of their transaction which can affect the shares on the NYSE and on the IDX. This study conducted by using daily data from January 2018 to December 2018. This study found that there is a significant effect of changes in TLKM stock prices on the NYSE in (t-1) period to changes in TLKM stock prices on IDX in t-period. This finding proves that there was the existence of transmission of information between the stock exchanges utilized by investors.

International Investors

Two possible causes of international stock price co-movement are examined: the existence of global common shocks and portfolio adjustments by international investors. Empirical analyses indicate that the former explains a significant part of the co-movement and the latter is unlikely to play an important role. We extend the analysis to intra-day high-frequency data. For example, when the Tokyo Stock Exchange begins its daily trading at 9:00 A.M. Japan Standard Time (JST), stock prices in Tokyo exhibit responses to preceding changes in New York. An analysis with minute-byminute data indicates that Tokyo's response to New York dissipates within about six minutes after opening. On the other hand, when the New York Stock Exchange (NYSE) opens at 9:30 A.M. Eastern Standard Time (EST), its response to Tokyo dissipates within 14 minutes. Thus, the movement of stock prices is transmitted rapidly across countries. Finally real-time simultaneous interactions between Shanghai (Shenzhen) and Tokyo are analyzed for a 30-minute period in the morning and a 60-minute period in the afternoon. Investors in Tokyo are watching stock prices in Shanghai, but not vice versa. Tight regulations on Chinese investors to prevent them from holding foreign stocks may be the reason why they do not pay any attention to stock price movements in Tokyo.
