Abstract

Investment in financial market is inextricably linked to risk. The risk cannot be eliminated, but indeed it can be minimized. By using Markowitz model, investor can gain optimal result while taking on acceptable risk. This study intends to examine the findings of optimal portfolio construction using Markowitz model on IDX 30. The method was quantitative descriptive. The population was all companies listed on IDX 30. Then, there were three companies chosen as the sample. The investigation of the three stocks yielded two efficient portfolios. First were the stocks of PT Bank Negara Indonesia, Tbk. and PT Astra International. The second was stocks of PT Bank Negara Indonesia, Tbk. and PT Adaro Energy Indonesia, Tbk.  Each stock provided a return of 1.03 % with the risk level of 7.75%, and 4.4% with the risk level of 8.49%. The conclusion is that by using these two portfolios, investor can get optimal expected returns with the degree of risk comparable to individual equities. Thus, it is suggested for the investor to apply the calculation of Markowitz model on Indonesia Stock Exchange over a longer period than the one used in this study. It is also suggested for them to select the portfolio in accordance to their preferences.

Abstract

The development of information and communication technologies has shifted marketing strategies toward digital methods, one of which is Instagram marketing. Instagram marketing is believed to foster customer-based brand equity within the current coffee-to-go industry market conditions.  This study aims to address gaps in past research, particularly the inconsistent findings and the limited investigation of brand experience as a mediator linking Instagram marketing with customer-based brand equity in the coffee-to-go sector.A quantitative research method with an explanatory survey was employed. The sample consisted of 125 respondents who were consumers of the coffee-to-go industry and had viewed content or Instagram accounts of a coffee-to-go brand. The sampling techniques used were purposive and incidental sampling. All instruments were valid and reliable, and all data met the Classical Assumption Test requirements. Hypothesis testing was conducted using Process Macro by Andrew F. Hayes in SPSS v27. The findings of this study reveal that Instagram marketing positively impacts brand experience; brand experience, in turn, positively affects customer-based brand equity. Additionally, Instagram marketing shows a significant influence on customer-based brand equity, with brand experience serving as a partial mediator in this relationship.
