Socially responsible investing is becoming more popular among people because people are becoming more concerned about the environment and society. Socially responsible investors screen the company by considering the ESG factors. The question raced is whether socially responsible investing improves the portfolio performance and how the funds perform during uncertain times like the Covid-19 pandemic. Since many critics of ESG funds say that the ESG funds’ performance highly depends on Software and Service company stocks, so the relevance of Software and Service companies in the fund has been analyzed in this research. The portfolios have been formed by using the Markowitz mean-variance portfolio model, and the performance of the minimum variance portfolio has been studied. The fund performance has been analyzed using the Sharpe ratio, and the result concludes that the ESG fund performance with minimum variance has an abnormally high Sharpe Ratio of 10.8. A similar type of performance was identified during the Covid-19 pandemic. The abnormally high Sharpe ratio will encourage investors to move towards socially responsible investing.

The Portfolio strategies are the effective investment tools pertaining to active and passive investment approaches. This signifies the investor’s inclination of buying and selling the risky and risk-free assets. The research includes four strategies namely buy and hold strategy, dynamic asset allocation, strategic asset allocation and tactical asset allocation along with their dimensions. Strategies based hypothetical portfolios are generated on the basis of 14 years’ stock prices (2005-2017). The annually and monthly risk-adjusted return ratios; Sharpe ratio, Treynor’s measure, CAPM and Jenson Alpha are calculated individually. Simulated annualized portfolios generate significant result with Sharpe and treynor measure. Alpha return is generated with buy and hold if based on growth in stock prices. For empirical result, One-way analysis of variance (ANOVA) is used for studying the relationship between the strategies. Post hoc Tukey’s test is applied to find the difference between the strategies. The ANOVA and Tukey’s post hoc test for monthly portfolios gives significant results with three measure Sharpe ratio, CAPM and Jenson Alpha. No empirical significant result is measured on the basis of treynor measure.

The current redenomination of the rupiah needs to be implemented in Indonesia. The declining value of the rupiah is one reason the government wants to increase the dignity of the rupiah and in Indonesia the largest denomination now is Rp 100,000.-. The rupiah is the second largest in the world after Vietnam's 500,000 Dong. This study aims to determine whether there is a difference of knowledge and perception between the actors of SMEs men with female SMEs actors. The sample in this study amounted to 100 respondents UMKM perpetrators. The data used in this study is the primary data. The method of analysis used in this study is the difference test two free sample average (Independent sample t-test). The result of the test analysis difference of two free samples indicate that, firstly, there is no difference of understanding between the SMEs of men and the female SMEs against the policy of redenominasi rupiah which means most of UMKM perpetrators understand redenominasi rupiah. Secondly, there is no difference of perception between male SMEs and female SMEs against rupiah redenomination policy which means that most of SMEs actors agree to redenominasi rupiah. The suggestion in this research is government to socialize about existence of policy redenominasi rupiah as soon as possible by conducting socialization directly and through mass media so that perpetrator of SMEs actors better understand and more understand about existence of policy redenominasi rupiah. Redenominasi rupiah saat ini perlu dilaksanakan di Indonesia. Nilai rupiah yang semakin melemah menjadi salah satu alasan pemerintah ingin meningkatkan martabat rupiah dan di Indonesia uang pecahan yang terbesar saat ini adalah Rp 100.000,-. Uang rupiah tersebut merupakan pecahan terbesar kedua di dunia setelah mata uang Vietnam yang mencetak 500.000 Dong. Penelitian ini bertujuan untuk mengetahui ada tidaknya perbedaan pengetahuan dan persepsi antara pelaku UMKM laki-laki dengan pelaku UMKM perempuan. Sampel dalam penelitian ini berjumlah 100 responden pelaku UMKM. Data yang digunakan dalam penelitian ini adalah data primer. Metode analisis yang digunakan dalam penelitian ini adalah uji beda dua rata-rata sampel bebas (Independent sample t-test). Hasil analisis uji beda dua rata-rata sampel bebas menunjukkan bahwa pertama tidak terdapat perbedaan pemahaman antara pelaku UMKM laki-laki dengan pelaku UMKM perempuan terhadap kebijakan redenominasi rupiah yang berarti pelaku UMKM sebagian besar paham redenominasi rupiah. Kedua, tidak terdapat perbedaan persepsi antara pelaku UMKM laki-laki dengan pelaku UMKM perempuan terhadap kebijakan redenominasi rupiah yang berarti pelaku UMKM sebagian besar menyetujui redenominasi rupiah. Adapun saran dalam penelitian ini yaitu pemerintah untuk mensosialisasikan tentang adanya kebijakan redenominasi rupiah secepatnya dengan cara mengadakan sosialisasi langsung dan melalui media massa agar pelaku UMKM lebih mengerti dan lebih paham tentang adanya kebijakan redenominasi rupiah.

The objective of this paper is to extend the information embedded in option-implied distribution to asset allocation model. This paper examines whether a parameter estimated from an option-implied distribution can improve a minimum-variance portfolio which consists of many risky assets. The option-implied distribution under a risk-neutral assumption is called risk-neutral density (RND) whereas a risk-world density (RWD) is calculated by incorporating a risk-premium. The computation of option-implied distributions is based on the Dow Jones Industrial Average (DJIA) index options and its constituents. The data covers the period from January 2009 until December 2015. Portfolio performance is evaluated based on portfolio volatility and Sharpe ratio. The performance of a portfolio based on an option-implied distribution is compared to a naive diversification portfolio. The empirical evidence shows that for a portfolio based on an option-implied distribution, the volatility of the portfolio is reduced and the Sharpe ratio is increased.

Several contributions in the literature argue that a significant in-sample risk reduction can be obtained by investing in a relatively small number of assets in an investment universe. Furthermore, selecting small portfolios seems to yield good out-of-sample performances in practice. This analysis provides further evidence that an appropriate preselection of the assets in a market can lead to an improvement in portfolio performance. For preselection, this paper investigates the effectiveness of a minimum variance approach and that of an innovative index (the new Altman Z-score) based on the creditworthiness of the companies. Different classes of portfolio models are examined on real-world data by applying both the minimum variance and the Z-score preselection methods. Preliminary results indicate that the new Altman Z-score preselection provides encouraging out-of-sample performances with respect to those obtained with the minimum variance approach.

The sense of gratitude that women have is not always the same between single and married women. Subjects in this study were 46 participants aged 22-36 years. The instrument used in this study was the GQ-6 gratitude scale compiled by McCullough, Emmons & Tsang. The data analysis used was the 2-sample difference test technique, namely the Independent sample t-test. Based on the results of the research data analysis, it can be concluded that there are significant differences in single and married women related to the level of gratitude. This can be seen from the results of statistical data analysis with the t test technique which shows a probability value of 0.034> 0.05 which indicates a significant difference. Thus the difference in the average actually occurs in real terms. In conclusion, married women have a higher level of gratitude (M = 35.95) than single women (M = 34.04).  Rasa kebersyukuran yang dimiliki oleh perempuan tidak selalu sama antara perempuan lajang dan menikah. Subjek dalam penelitian ini berjumlah 46 orang partisipan yang berumur 22-36 tahun. Instrumen yang digunakan dalam penelitian ini adalah skala syukur GQ-6 yang di susun oleh McCullough, Emmons & Tsang. Analisis data yang digunakan adalah teknik uji perbedaan 2 sampel yaitu Independent sampel t-test. Berdasarkan hasil analisis data penelitian dapat diperoleh kesimpulan bahwa terdapat perbedaan yang signifikan pada perempuan lajang dan sudah menikah terkait dengan tingkat kebersyukuran. Hal tersebut dapat dilihat dari hasil analisis data statistik dengan teknik uji t yang menunjukkan nilai probabilitas 0,034 > 0,05 yang mengindikasikan adanya perbedaan yang signifikan. Dengan demikian perbedaan rata-rata yang ada benar-benar terjadi secara nyata. Sebagai kesimpulannya adalah perempuan yang sudah menikah memiliki tingkat kebersyukuran yang lebih tinggi (M = 35,95) dibandingkan perempuan lajang (M = 34,04).
