Abstract

The rate of return (return) and risk are inseparable in investing activities. One equilibrium model that describes the relationship between return and risk assumes that the expected return is influenced by more than one macroeconomic factor. Furthermore, the causal relationship between stock returns and macroeconomic factor returns was analyzed using VAR. The application of VAR in this study is to predict stock returns through the stages of checking data stationarity, determining the optimal lag length, testing Granger causality between variables, estimating VAR model parameters and Portmanteau diagnostic tests, and predicting stock returns. The results show that the VAR (1) model is the most appropriate model to describe the relationship between stock returns and macroeconomic factor returns with a significant model owned by BBCA, ICBP, INTP, KLBF, and SMGR stocks. Furthermore, the VAR (1) model is used to predict the five stock returns. The prediction results show that INTP's stock returns are negative while the returns of the other four stocks are positive. This shows that INTP shares experienced a capital loss, while the stock returns of BBCA, ICBP, KLBF, and SMGR experienced capital gains

Abstract

Critical thinking skill is necessary to be learned by every students, because by thinking critically students are able to understand other mathematical skills. One of the problems that can improve critical thinking skills is Problem With Contradiction Information (PWCI), which means problem that contains wrong information. Every student has their own characteristics, it also influences their critical thinking. One of the ways to identify a type of personality people is by using the Myers Briggs Type Indicator (MBTI), which classifies humans based on several perspectives, such as how to understanding and receiving information (Sennsing-Intuition), also how to make a conclusion and decision (Thinking-Feeling). The purpose of this study is to describe the critical thinking skills of students with sensing, intuition, thinking and feeling personalities. This research is a descriptive study with a qualitative approach. This research was based on SMAN Arjasa, and the subject was 8 students consisting of 2 students each with sensing, intuition, thinking and feeling personality. Data collection methods used are test and interview. The analysis technique used is the analysis of test results, interviews and triangulation.  The results of this research revealed that students with sensing, intuition, thinking and feeling personality types have their own characteristics when solving the problem. The results of the critical thinking test found that there were no students who were able to fulfill critical thinking skills but there were students who were able to find contradictory information in the question
