We applied the concept of change of probability measures considering Girsanov’s and the Radon–Nikodym theorems. We found the generator of the Backward Stochastic differential equations defined and employed the Hamilton–Jacobi–Bellman (HJB) dynamic programming in finding the stochastic optimal controls of interest.","PeriodicalId":54088,"journal":{"name":"International Journal of Financial Engineering","volume":"15 5","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139450975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The daily data have been used from January 1, 2013, to February 24, 2023, archived from the wind database. We use a nonlinear autoregressive distributed lag (NARDL) framework for the research to be empirical. The NARDL test reveals the presence of a nonlinear asymmetric relationship, both in the long-run and short-run, among the MSCI-China, MSCI-World, S&P500-ENERGY indices, and the price of Bitcoin. The S&P 500 energy index and Bitcoin price have an inverse asymmetric connection. The prices of Bitcoin are positively influenced by both positive and negative shifts in the MSCI-CHINA and MSCI-WORLD indices. Overall, this study underscores the growing significance of the cryptocurrency market as a hedge against risks, offering evidence that Bitcoin can be perceived as a safe haven amidst the turbulence of the energy market. This insight holds implications for Bitcoin investors, suggesting its potential as a refuge in times of energy market instability.","PeriodicalId":54088,"journal":{"name":"International Journal of Financial Engineering","volume":"116 6","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138953803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It does not value pairs of European spot and futures options consistently even though they are theoretically equivalent. The inconsistency arises from the way dividend yield is incorporated into the jumps and probabilities. In addition, the model also has the tendency to undervalue American options due to suboptimal early exercise decisions. While the lingering effect of this problem diminishes asymptotically, it is nonetheless a concern for someone just beginning to learn the model or in applications where the use of a sufficiently large binomial tree is not practical or economical. We propose a simple modification to solve the problem and demonstrate the effectiveness of the solution.","PeriodicalId":54088,"journal":{"name":"International Journal of Financial Engineering","volume":"31 18","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139006684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One such possible hedging strategy may be the management of a portfolio constituted by the futures contracts holding a short position with respect to the basic asset. Besides that, the amount of having been sold futures is to satisfy the restrictions on the admissible minimal and maximum volume at each instant of time. The goal of such portfolio management is the increase of the weighted average price of futures sales through the speculative transactions realized in the real-time regime. Moreover, as feedback in the process of such management realization, one may use the prices of being executed market bargains only. The efficiency of the proposed hedging scheme is demonstrated by its comparison with the financial results achieved by the static hedging in the process of their both practical realizations based on the historical market prices. In this paper by the “dynamic hedging” concept, one means the execution of speculative transactions with futures taking a short position to provide the additional value of basic asset taking a long position. This notion is introduced in counterweight to the “static hedging” concept when the futures quantity does not vary in time and which goal is to preserve the basic asset value only.","PeriodicalId":54088,"journal":{"name":"International Journal of Financial Engineering","volume":"7 2","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138607141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rapid development and advancement in technology and consumer needs have made the retail sector hold a pivotal role in our economy. Organized retailing has brought in more satisfied and convenient shopping practices among consumers. The major segments covered in organized or modern retailing include store-based and nonstore-based. The organized retail market has a lot of scope and opportunities due to value for money, changing consumer shopping patterns, rural market, enhanced middle-class consumers, growth and awareness of consumerism, technological impact, media and social media apprising and increased income (Suresh, 2019). This study focuses on the supermarket segment of organized retailing, where the major daily groceries and monthly household needs of consumers are extensively delivered. Even though the major online grocery stores and applications have become a part of consumers’ lives, supermarkets and hypermarkets are enduring and growing due to the constant support offered by consumers of all categories. Despite the pandemic hindrances, the organized retailing sectors have registered strong growth and performance. This study aims to analyze consumer preferences for supermarkets and the reasons behind choosing supermarkets. The data were collected from 128 respondents who were shoppers of various supermarkets with reference to Chennai city. The data were collected through a self-administered survey using a structured questionnaire. The analysis of data was performed using descriptive statistics and SPSS AMOS.

Taking the stock price yield of AH stock as the explanatory variable, this paper adopts the panel quantile model to probe into the linkage mechanism of AH stock price from five aspects such as risk difference, liquidity difference, demand elasticity difference, information asymmetry and new regulation policy of reduction. Due to the herding effect, information asymmetry has a negative effect on the H-share yield in the income and loss intervals, and a positive effect in the stable interval. The negative effect of liquidity difference on the H-share yield in the loss interval is converted into the positive effect in the income interval, but it is the most sensitive in high risk areas. The influence of demand elasticity on H-share yield is characterized by the typical characteristics of Chinese stock market “chasing after go up and killing cheapen” or “buying the winners”. Risk difference is not obvious because the behavior of risk lover and risk averter is offset by each other. The introduction of a 2017-year reduction in the new rules has significantly reduced the share price yield of H-shares. Finally, some suggestions are put forward for investors to invest and avoid risk in AH stocks and some specific policy implications for financial regulators are also provided based on these results.","PeriodicalId":54088,"journal":{"name":"International Journal of Financial Engineering","volume":"41 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135430793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We form a portfolio of two well-known ETFs and apply some well-known TTRs like Moving Average (MA), Relative Strength Index (RSI) and Moving Average Convergence Divergence (MACD) techniques to this simple proposed portfolio from January 31, 2007 to August 31, 2021. We design two strategies: (1) Long/Money and (2) Leverage/Money. We compare the risk-adjusted performance of some well-known trading rules applied to our proposed portfolio with strategy (1), Long/Money, which is a more conservative investment strategy, to the risk-adjusted performance of 14 top-ranked BFs. The best trading rules with strategy (1) applied to our portfolio outperform all the top-ranked BFs for the entire period and over two equal sub-periods. Similarly, the best trading rules applied to our portfolio with strategy (2) outperform the ‘market’, a Buy and Hold (B&H) strategy for the entire period and over two equal sub-periods.
