Purpose - The purpose of this study is to show the need to use the past long-term returns for investment decisions in U.S. equity funds and to suggest an investment strategy using long-term returns. Design/methodology/approach - This study solves the problem of high return volatility in long-term returns and proposes new investment portfolios based on the behavior of fund investors according to past returns. For the investment portfolio of this study, 60 months are divided into several periods and the average of the performance ranks for each period is used. Findings - First, funds with high average returns over multiple periods have lower future outflows and higher future returns than funds with high 60-month cumulative returns. Second, funds with low average returns over multiple periods have lower future inflows and lower future returns than funds with low 60-month cumulative returns. The findings mean that when making decisions based on past long-term returns, it is a smarter investment choice to buy funds with high average returns over multiple periods and sell funds with low average returns over multiple periods. Research implications or Originality - This study shows that it is necessary to use long-term returns in fund investment by analyzing the characteristics of the portfolio based on past returns. In addition, the study is meaningful in that it suggests a way to use long-term returns more efficiently based on the behavior of fund investors and shows that such investments lead to higher returns in the future.

Feedback herding strategy in stock market means considering other investor's strategy as a basis of market forecasting of next term. Generally, individual investors use that strategy which mimics the strategy of institutional investors. When it is used in stock market, both kind of investors, preceders and followers, can take the higher average of rate of return to normal market in which no feedback herding strategy is not use, the more investors take part in. And variance of return, the risk of investment, are same to both group.

In the later quarter of the twentieth century, the need for foreign capital is realized among the various countries of the world. Developing countries especially developed multi-pronged strategies to attract foreign capital into the country. One such strategy is the adoption of liberalization policy. Almost all the developing countries started opening their economy, out of the compulsion, to achieve faster rate of economic growth and development. Even a communist country like China adopted liberalization policy as a strategy for accelerated economic growth during 1979. India also joined the race by 1991, when the government announced the policy of liberalization. The importance of FDI extends beyond the financial capital that flows into the country. The huge size of the market in this sector and high returns on investment are two important factors in boosting FDI inflows to power sector. 100 percent FDI is allowed under automatic route in almost all the sub sectors of power sector except the atomic energy. Major foreign investment is made in this sector during 2000 to 2009 is Mauritius with an investment of US$ 4490.96 i.e., 4.24 percent of the total FDI inflows into the country during the period. The estimation of future FDI flow shows a marginal decline in the year 2010. Then from 2011 to 2015 onwards upward trend of FDI was observed.

Industrial revolution 4.0 makes business competition more challenging and will impact the instability of the company's financial performance. Dynamic environmental conditions make it difficult for companies to make predictions in making decisions. Investing in information technology (IT) is one way for companies to maintain financial stability and competitive advantage in dynamic competition. Resource-Based Theory (RBT) explains that information technology (IT) is a resource that can create a competitive advantage for the company. This study aims to examine the moderating role of dynamic industrial environments and IT strategic emphasis on the relationship between a lag effect of IT investment and firm's financial performance volatility. Using the data of companies listed on the Indonesia Stock Exchange (IDX) for five years starting from 2013-2017, the method used to estimate the research model's parameters is the generalized method of moments (GMM) approach. The results show that the industrial environment and the emphasis on IT strategy have a role in moderating and strengthening the relationship between the time lag in IT investment in reducing the firm's financial performance volatility.

This paper analyzes a robust optimal reinsurance and investment strategy for an Ambiguity-Averse Insurer (AAI), who worries about model misspecification and insists on seeking robust optimal strategies. The AAI's surplus process is assumed to follow a jump-diffusion model, and he is allowed to purchase proportional reinsurance or acquire new business, meanwhile invest his surplus in a risk-free asset and a risky-asset, whose price is described by an Ornstein-Uhlenbeck process. Under the criterion for maximizing the expected exponential utility of terminal wealth, robust optimal strategy and value function are derived by applying the stochastic dynamic programming approach. Serval numerical examples are given to illustrate the impact of model parameters on the robust optimal strategies and the loss utility function from ignoring the model uncertainty.

우리나라는 글로벌 기술경쟁력 제고를 위해 연구개발에 대한 투자를 지속적으로 증대시켜왔다. 우리나라의 GDP대비 연구개발투자비는 4.15%로 세계 1위 수준이며, 이 가운데 기업부문은 전체 투자의 78.5%를 차지하며 매우 중요한 역할을 수행하고 있다. 그러나 더 이상 양적인 투자 증대에는 한계가 존재하기에 R&D투자에 대한 질적 수준을 높여 효율성을 제고하기 위한 노력이 절실히 필요한 실정이다. 이러한 연유로 본 연구에서는 기업의 경영성과를 제고하기 위한 방안을 강구하기 위한 연구를 수행하였다. 이를 위해 그동안 학문적으로 그 중요성이 강조된 연구개발 초기 단계인 기술전략과 기술기획 역량이 기업의 성과제고에 미치는 영향요인을 실증적으로 검증하고자 하였다. 실증분석 결과, 기술전략과 기술기획 활동이 경영성과 제고에 매우 유의미한 영향을 미치는 것으로 나타났으며, 조직유연성의 경우 개별적인 요인 또한 중요하지만 기술기획 활동을 긍정적으로 조절하여 경영성과 제고에 기여함을 확인하였다. 본 연구에서는 기업의 기술혁신 활동을 실제적으로 파악하기 위해 기업연구소를 운영하고 있는 전체 기업을 대상으로 표본조사를 수행하였으며, 분석방법으로는 다중회귀분석과 분위회귀분석을 활용하였다.

인터넷망에서 동영상 콘텐츠를 스트리밍 서비스로 시청할 수 있게 해주는 OTT 서비스는 최근 많은 각광을 받고 있으며 이용자수 또한 가파르게 증가하고 있다. OTT 회사가 전통적인 미디어 회사들 및 타 OTT 회사들과 관계에서 경쟁 우위를 확보하기 위해 더 많은 콘텐츠를 확보하는 것은 당연한 전략일 것이다. 하지만 OTT 사업자로부터 유발된 인터넷 트래픽양 또한 더불어 같이 증가하게 되므로 이를 전송해 주어야 하는 인터넷 서비스 회사의 설비 투자도 증가해야 한다는 의견도 있다. 본 연구에서는 대표적인 OTT 회사인 넷플릭스의 콘텐츠 투자가 자사의 매출 증가와 인터넷 서비스 회사의 인터넷 망 투자 증가에 어떠한 영향을 미치는 지를 시차 분포 모형을 통해 실증적으로 분석하였다. 분석결과는 넷플릭스의 콘텐츠 투자는 자사의 매출 증대에 기여하고 있으며, 또한 인터넷 서비스 사업자 들의 인터넷 망투자 증가에도 영향을 미치는 것을 보여 준다. 이는 OTT 사업자의 콘텐츠 확대 전략이 유효한 경영 전략임을 확인해주며, OTT 사업자 들로부터 우발디는 막대한 인터넷 트래픽을 지연없이 전송하기 위한 인터넷 망 설비 투자 비용을 OTT 사업자 들이 분담할 필요가 있다는 연구 결과 들을 실증적으로 지지한다.

This paper proposes the Pyramid strategy which is based on the straddle sell. The Pyamid strategy has multi-entry features with starting date and delta parameters. And It is hedged against a loss by mutual trades and dynamic ripples. This paper analyzes the profit and MDD(maximum draw down) of the Pyramid strategy on system trading. The portfolio tool is used for the experiment which is one of the Multicharts' package. The Multicharts is a good trading system of recent years. For the experiment, three call options and three put options are used at october in 2009. Two parameters are used which are the starting date from first October to twentieth October in 2009 and delta from eight percent to fifty percent. As a result, the profit of composite option is about 3 million won. If the strategy starts before the beginning of option month, investors feel uncomfortable because of a large MDD. If a delta belows 20%, it shows high profit and the ratio of profit and MDD builds up a low value. However a low delta makes frequent trades and results in a loss unless increasing entry levels which mean more amount of investment. This work provides a safer trade system than native option trades. It is important how much levels of multi-entry are acceptable. And an amount of investment with appropriate levels of multi-entry is a subject of a future study.

The objective of the study is to propose the catch-up strategy of Hyundai Kia to become the globally leading company in the automobile industry. For this, we try to compare Hyundai Kia with three leading automobile companies: Toyota, VW, and GM by using the Generalized Double Diamond Model. As a result, we present three ways that Hyundai Kia can become a "First Mover." The three strategies are : 1) controlling increase of wage, raising productivity, and increasing R&D investment 2) increasing overseas investment of the small and medium sized automobile factories 3) pursuing the two tracks strategy of a public car and a prestige car more aggressively. This study is significant in the fact that it presents the catch-up strategy of Hyundai Kia in the automobile industry, of which the leaders can not be changed easily, by the Generalized Double Diamond Model approach.

The objective of this study was to investigate the impacts of working capital policy and strategy on a firm's performance including profitability and market value. By applying One-Sample T-Test, working capital investment and financing policies were classified into the three sub-policies and strategies: aggressive, moderate, and conservative, unlike previous studies using two sub- policies and strategies. The results showed that the SET-listed companies in all seven industry sectors primarily adopted an aggressive working capital investment policy and a conservative working capital financing policy, so-called as moderate working capital management strategy (MWS), at 49.40%. While the firms adopted and conservative working capital management strategy (CWS), 45.70%, followed by the aggressive working capital management strategy (AWS), at 4.90%. When examining the impacts among three-sub policies and strategies on a firm's performance, it was found that the conservative working capital financing policy led to the highest profitability and market value in all industry sectors. The findings also revealed that the aggressive strategy has no impact on a firm's performance in terms of profitability and market value.
