Purpose - The purpose of this study is to re-examine the disclosure effect of stock splits and long-term performance after stock splits using stock split data over the past 10 years, and infer the motivation (signal or opportunism) of stock splits. In addition, we focus on exploring the determinants of the short- and long-term market response to stock splits. Design/methodology/approach - We measure the short-term market response to a stock split and the long-term stock performance after the stock split announcement using the event study method. We analyze whether there is a difference in the long-term and short-term market response to a stock split according to various company characteristics through univariate analysis and regression analysis. Findings - In the case of the entire sample, a statistically significant positive excess return is observed on the stock split announcement date, and the excess return during the 24-month holding period after the stock split do not show a difference from zero. In particular, the difference between short-term and long-term returns on stock splits is larger in companies with a large stock split ratio, small companies, large growth potential, and companies with a combination of financial events after a stock split. Research implications or Originality - The results of this study suggest that at least the signal hypothesis for a stock split does not hold in the Korean stock market. On the other hand, it suggests that there is a possibility that a stock split can be abused by the manager's opportunistic motive, and that this opportunism can be discriminated depending on the size of the stock split, corporate characteristics, and financing plan.

The research looks into the impact of stock split announcements on stock prices and market efficiency in the Colombo Stock Exchange (CSE). This research uses a sample of 26 stock split announcements that occurred between 2020 and June 2021. According to the Global Industry Classification Standards, the stock split announcements covered in the study pertain to 26 businesses and 9 industries (GICS). To obtain the results, the usual event research methodology is used. The findings demonstrate significant average abnormal returns of 15.01 percent on the day the stock split news is made public and abnormal returns of 4.11 percent and -4.05 percent one day before and after the stock split announcement date, respectively. The study's findings revealed significant positive abnormal returns one day before the disclosure date, indicating information leakage, and significant negative abnormal returns the next day after the announcement date, indicating CSE informational efficiency. Because stock prices adapt so quickly to public information, these findings support the semi-strong form efficient market hypothesis, which states that investors cannot gain an abnormal return by trading in stocks on the day of the stock split announcement.

Purpose - This study examines the information effect and trading behavior of investors for the 430 stock split data from January 2004 to June 2018 in the Korean stock market. Design/methodology/approach - The stock split samples are classified into two groups by split ratio as well as three groups by price level prior to split. We also investigate the trading behavior of investors categorized by institutional versus individual investors. Findings - First, we find a significantly positive information effect on the announcement day. In particular, the information effect is more distinct in the group of larger split ratio and higher price level of stocks. Second, we find a huge increase in turnover following the stock splits, which mainly results from the trading by individual investors. Also, the increase in turnover by individual investors is evident in the group of larger split ratio and higher price level of stocks. Third, the stock splits have a negative impact on the long-term stock performance. The negative buy-and-hold abnormal return(BHAR) makes no difference in the groups by split ratio as well as price level of stocks. Lastly, we find individual investors tend to buy splitted stocks, which exhibit the long-term under-performance. Research implications or Originality - The results in this paper suggest that the liquidity hypothesis is not supported in the Korean stock splits. In addition, we observe that individual investors are exposed to losses due to their unfavorable trading behavior following the stock split.

The event study analyzes returns around event date at a time. Event study provides estimation periods and cumulative returns. Stock split announcements are generally associated with positive abnormal returns. It is important to investigate the responses of stocks to new information contained in the announcements of stock splits. So It is important to study the long term performance in the case of Stock Split. This Study forced to two approach method in evaluating the performance, the event time portfolio approach and calendar time portfolio approach. The event time portfolio approach exists the CAR model, BHAR model and WR model. And the calendar time portfolio approach has the 3 factor model, 4 factor model, CTAR model, and RATS model.

The major objective of this study is to investigate the dynamic behavior evaluation of split PC sleepers for railway turnout by the field test. In railway engineering, a turnout is necessary to allow a vehicle to move from one track to another. So, turnout is required very complex railway technologies such as lolling stock, track. In reference to conventional line speed-up and improvement railway, accurate assembly of turnout affects travel ins qualify of turnout area and running safety. Because of heavy weight and a large volume of the long sleeper used to turnout and car limit, transport and the prerequisite for trouble-free transport of the factory pre-assembled major turnout components is achieved through division of long sleepers. The one of the advantages for using a split sleeper is to reduce the dynamic vibration according to the information of developed nations. Therefore, we investigate the characteristic of dynamic behaviors of split sleepers which are adopted for the first time to improve performance of turnout From the field test results of the split sleeper, it is evaluated that the modification of weight, material and stiffness compared with wood sleeper is very effective for the ballast safety. However, the decrease in vibration of split sleeper was not found out.

본 논문은 2000$\sim$2007년 5월까지 주식분할공시와 절차를 끝낸 122개사의 131개의 주식분할자료를 바탕으로 우리나라 주식시장에서 주식분할의 공시가 정보내용을 지니고 있는가를 살펴봄으로써 우리나라 유가증권시장에서의 신호효과에 대한 실증분석과 주식분할에 따른 유동성 효과에 대하여 분석한다. 본 연구는 주식분할이 수익률에 미치는 영향과 기업들이 주식분할을 실시하는 이유를 한국의 주식시장 자료를 이용하여 분석하였다. 본 논문의 실증결과를 분석하면 다음과 같다. 첫째, 우리나라 주식시장에서 신호효과에 따른 주식분할 공시일 전후에 초과수익률이 발생하는지 여부를 신주상장일 전후의 초과수익률 발생유무와 최대주주의 주식보유비율과 비교하여 검증한 결과 주식분할 공시일과 신주상장일에 양(+)의 초과수익률이 발생하는 것으로 나타났다. 또한 이러한 초과수익률은 분할 비율이 높을수록 초과수익률이 더 크게 나타나는 것으로 확인되었다. 이러한 실증분석 결과, 우리나라 주식시장에서도 일시적으로 신호가설이 성립하는 것으로 볼 수 있다. 둘째, 우리나라 주식시장에서 주식분할의 목적에 부합되는 유동성 증대의 결과는 분할비율이 클수록 거래량의 증가가 지속적으로 증가하는 것으로 나타났다. 또한 이러한 주식분할비율에 근거한 거래량의 증가는 분할비율이 작을수록 비교적 그 비율대로 증가하는 것으로 나타났으며, 장기적인 관점에서는 분할비율이 높을수록 거래량의 증가가 나타나는 것으로 확인되었다. 셋째, 주식분할에 따른 초과수익률은 공시일과 분할일에 발생하나 그 효과가 일시적으로 나타나는 것으로 확인되었으며, 유동성 증대효과는 단기적으로는 유효하나 점차 거래량이 시장거래량에 근접해가는 추세를 확인할 수 있었다.

본 연구는 우리 나라에서 최근에 다수의 기업들이 실시하고 있는 주식분할(Stock split)이 투자자들에게 실시기업의 미래의 경영상태를 양호하게 보도록 하는 정보를 시장에 신호하는 도구가 되고 있는지 살펴보았으며, Fama-Fisher-Jensen-Roll의 연구처럼 그 정보가 주식분할기업의 향후 배당가능성을 의미하는지를 조사하였다. 만약 배당 가능성이 주식분할의 동기가 아니라면, 다른 동기가 있는지도 검증해 보았다. 연구결과는 우리 나라 시장에서 주식분할공시가 주가에 영향을 주는 것으로 나타났으며, 그 동기가 주식분할실시기업의 향후 배당가능성은 아니며, 오히려 주식분할을 통해 주가를 적정거래범위내에 거래될 수 있도록 유도하려는 의도가 그 동기가 된 것으로 볼 수 있다.

본 연구에서는 1998년부터 2002년 동안 주식분할을 실시한 과거 거래소 상장기업을 대상으로 장기성과를 분석하였다. 장기성과는 Event-time 포트폴리오 접근방식으로 측정되어지는 BHAR과 CAAR을 이용하였고 또한 Calendar-time 포트폴리오 접근방식으로 1요인 CAPM 모형과 3요인 모형을 이용하였다. 분석결과 주식분할의 공시월 부근에서 유의적인 양(+)의 초과수익률을 발견할 수 있었다. 이러한 결과는 기존 국내 연구들에서 밝혀진 바와 같이 주식분할의 공시효과가 존재한다는 것을 재확인 한 것이다. 하지만 이후 기간별 BHAR과 CAAR 모두 유의적인 음(-)의 초과수익률이 나타났으며, 이러한 결과는 Calendar-time 포트폴리오 접근방식인 1요인 CAPM 모형과 3요인 모형에서도 재확인 할 수 있었다. 분할비율에 따른 BHAR과 CAAR을 분석한 결과 분할비율이 높은 기업군도 주식분할 이후 여전히 음(-)의 초과수익률이 나타났으며 주식분할 이전 보다 이후에 영업성과가 더 악화되는 것으로 나타났다. 따라서 주식분할이 기업의 수익성이 개선된다는 신호로 보기에는 무리가 있었다. 배당성향의 증감에 따라 표본을 분류하여 장기성과를 분석한 결과에서 두 표본 간에 뚜렷한 차이를 발견할 수 없었다. 본 연구의 결과를 통하여 볼 때 주식분할은 한국 주식시장에서 단기적으로는 주가에 양(+)의 영향을 미치고 있지만 장기적으로는 주식분할이 주가에 미치는 영향은 없는 것으로 판단된다.

This review presents a series of Key Performance Indicators (KPI) to assist Asian smallholder dairy farmers in identifying the possible causes for their poor farm performance and profitability. When assessing farm profitability, these indicators can be split into two types, those diagnosing problems with feeding management and those indicating poor herd management. As home grown forage is generally cheaper to source than purchased forage, the more produced on farm, the better. Too many stock on limited land is a common feature on Asian dairy small holdings. Unlike other classes of livestock, milking cows have very high nutrient requirements, therefore high quality forages and concentrates are essential for profitable dairying. Milk income less feed cost is one of the simplest and easy to measure indicators of farm profitability and is also quick to respond to small changes in farm practices. Problems with herd management can be diagnosed using measures such as the proportion of cows actually milking in the herd or their peak yield and persistency of production. There are also simple indicators of herd reproductive performance and of health and growth of young stock that assist in searching for the underlying causes of poor farm profitability.
