Abstract

In practice, there are some aspects which contribute to the decision making process. One of those aspects is the psychological aspect which cannot be separated from human being. The psychological aspect of the study of finance is called the study of behavioural finance (cognitive bias, emotional bias, and social bias) could lead to investor’s irrationality in decision making. This study aimed to analyze the influence of dissonance bias, overconfidence bias, and herding bias on investment decision in Investor Club of Satya Wacana Christian University (SWCU). This study utilizes the purposive sampling method. The sample in this study covers the whole investor in Investor Club of SWCU. The results of this study indicate that: (i) Cognitive dissonance bias has an insignificant influence to investment decision ; (ii) Overconfidence bias has a positive and significant influence to investment decision; (iii) Herding bias has an insignificant influence to the investment decision. This means that investors tend to use the emotional aspect rather than on the cognitive and social aspects of investment decision making. As a result, investors are overconfident of their ability and the outcome of investment decisions is not maximal and can cause losses. DOI: https://doi.org/10.26905/afr.v1i1.1745

Abstract

The cryptocurrency market is a market that attracts researchers and investors because it is open every day. This can be seen by the anomalies that occur in the cryptocurrency market. This research uses cryptocurrencies with the largest market cap in 2020, namely Bitcoin, Ethereum, Tether, XRP, and Bitcoin cash as research objects. The data in this study uses daily returns for testing the day of the week effect and daily volatility on the cryptocurrencies under study. This study uses GARCH (1,1) to determine the day of the week effect and daily volatility in the cryptocurrency under study. The results of this study indicate that there is a day of the week effect and daily volatility in the cryptocurrency under study, and it does not move freely. This causes the cryptocurrency market to become an inefficient market. The patterns that occur can be exploited by investors as well as other research on the cryptocurrency under study. Investors can avoid days that have high volatility for example in Bitcoin which experiences high volatility on Fridays and Saturdays because it has a high risk as well. Investors are advised to be able to trade on Thursday for high returns and less risk.

Investments are made to obtain future benefits. Stocks are one of the most popular investments in the capital market. The advantage that can be obtained from the stock investment is stock returns, where the returns obtained can be positive or negative. This study aims to analyze the influence of fundamental and macroeconomic factors on stock returns of manufacturing companies listed on the Indonesia Stock Exchange from 2016 to 2019. This study used secondary data and the sample of this research was 37 manufacturing companies obtained through the purposive sampling method with panel regression as the data analysis. The results showed that the fundamental factors that affect stock returns are Price to Book Value (PBV), while the Debt to Equity Ratio (DER) and Price to Earnings Ratio (PER) do not affect manufacturing stock returns. Some macroeconomic factors such as inflation, the BI Rate, and changes in world oil prices proved to not affect the stock returns of manufacturing companies. This research implies that manufacturing companies need to pay attention to Price to Book Value (PBV) in determining stock returns.
