Abstract

This study, conducted with a robust and transparent methodology, aims to determine the occurrence of market overreaction on the Indonesian stock exchange. We analyze two distinct periods, semiannual and annual, from 2016 to 2019, focusing on the LQ-45 index. Our methodology involves classifying stocks into two portfolios based on the Cumulative Abnormal Return (CAR) value. The winner portfolio represents one-third of the stocks with the highest CAR value, while the loser portfolio represents one-third with the lowest CAR value. The presence of overreaction is indicated when the loser's portfolio outperforms the winner's. Our findings from this rigorous methodology, which we detail in the paper, reveal a clear and novel phenomenon of market overreaction on the Indonesian Stock Exchange, particularly on stocks included in the LQ-45 index, but notably, only in the semi-annual period. There is no evidence of market overreaction for the annual period, suggesting a nuanced market behavior that warrants further investigation.

Abstract

Background: Hypertension is one of the leading causes of death among degenerative diseases, leading to heart failure, stroke, and other complications in the elderly. Hypertension can be treated pharmacologically or non-pharmacologically. One non-pharmacological method that can be used is autogenic relaxation combined with listening to classical music. This study aims to determine the effect of autogenic relaxation combined with listening to classical music on reducing blood pressure in elderly hypertensive patients. Objectives: To determine the effect of autogenic relaxation combined with listening to classical music on reducing blood pressure in elderly hypertensive patients. Methods: This study was quantitative with a pre-experimental one-group pretest-posttest design. The study was conducted in Gunung Sinogo Hamlet, Ngargorejo Village, Ngemplak District, Boyolali Regency. The sampling technique used was purposive sampling. The intervention was conducted eight times over four weeks, each session lasting 20 minutes. The autogenic relaxation session was accompanied by classical music, Mozart's Piano Concerto No. 21, II. Data analysis used the Shapiro-Wilk test and paired sample t-test. Results: The results showed that the majority of respondents with hypertension were aged 60-74 years (81%), and the majority of respondents were female (81%). Furthermore, a decrease in systolic blood pressure of 16 mmHg and a decrease in diastolic blood pressure of 11.57 mmHg was found. The statistical test yielded a p-value <0.001, indicating a significant effect of autogenic relaxation through listening to classical music on lowering blood pressure. Conclusion: This study demonstrates a significant effect of autogenic relaxation through listening to classical music on lowering blood pressure in hypertensive patients.
