摘要

有关资本市场效率的研究已经开展了很多,但目前缺乏对其他金融市场如技术市场中市场效率的弱形式的研究。本研究的目的是分析covid -19大流行期间科技股市场弱形式的效率。本研究使用的数据是印度尼西亚证券交易所2020-2022年科技股的每日收盘价数据。本数据来自雅虎财经科技。使用的分析工具是运行测试,然后是增强的Dickey-Fuller和相关图,用于鲁棒性检查。本研究结果表明,有几只科技股以弱形式包含在有效形式中,这意味着这些股票在Covid-19大流行期间的价格是随机游走的,因此技术分析无法应用于分析几只科技股,即EMTK, MTDL和LUCK。本研究结果表明,投资者在交易EMTK、MTDL和LUCK股票时不使用技术分析。

Weak Market Efficiency for Technology Stocks During The COVID-19 Pandemic
Many studies related to capital market efficiency have been carried out, but currently there is a lack of research on weak forms of market efficiency in other financial markets such as the technology market. The purpose of this study is to analyze the efficiency of the weak form of the market for technology stocks during the Covid-19Pandemic. The data used in this study is data on daily closing prices for technology stocks from 2020-2022 from the Indonesia Stock Exchange. This data is obtained from Yahoo Finance Technology. The analytical tool used is the Runs Test followed by the Augmented Dickey-Fuller and Correlogram for Robustness Checking. The results of this study state that there are several technology stocks that are included in the efficient form in a weak form, which means that the prices of these stocks during the Covid-19 Pandemic are random walk, so that technical analysis cannot be applied in analyzing several technology stocks, namely EMTK, MTDL and LUCK. The results of this study suggest that investors in trading EMTK, MTDL and LUCK shares do not use technical analysis.
