Abstract

This research is to determine the level of investment risk and stock returns as well as grouping efficient shares and inefficient shares of coal mining companies through the Capital Asset Pricing Model (CAPM) method for the 2019-2021 period. The research method used is descriptive method with a quantitative approach, while the data analysis method uses the Capital Asset Pricing Model (CAPM) method. The results showed that there were 8 shares of coal mining companies with a beta (systematic risk) value of greater than 1 (β > 1), and 16 shares of companies with a beta of less than 1 (β < 1. The highest RI was found in HRUM shares with a rate of return of 0.07650 or 7.65%, while the lowest Ri is found in BOSS shares with an average rate of return of -0.06000 or - 6%. The highest E(Ri) value is found in DOID shares with a value of 0.00177 or 0.18%, while the lowest E(Ri) is found in GEMS companies with a value of 0.00126 or 0.13%. There are 16 shares of coal mining companies which are classified as efficient shares consisting of shares of ADRO, BSSR, BYAN, DOID, DSSA, FIRE, GEMS, iHRUM, INDY, iITMG, MBAP, MYOH, iPTRO, SMMT, iTOBA, and BRMS, as well as 8 inefficient stocks namely ARII, BOSS, BUMI, DEWA, ​​GTBO, KKGI, PTBA, and SMRU.
IDX上市煤炭企业2019-2021年投资风险与股票收益分析
本研究通过资本资产定价模型(CAPM)方法确定2019-2021年期间煤矿公司的投资风险水平和股票收益水平,并对有效股和无效股进行分组。研究方法采用定量方法的描述性方法,数据分析方法采用资本资产定价模型(CAPM)方法。结果表明,贝塔(系统风险)值大于1 (β > 1)的煤矿公司有8股,贝塔值小于1 (β < 1)的煤矿公司有16股。hrm股票的平均收益率最高,为0.07650或7.65%,而BOSS股票的平均收益率最低,为-0.06000或- 6%。E(Ri)值最高的是DOID股票,值为0.00177或0.18%,而E(Ri)值最低的是GEMS公司,值为0.00126或0.13%。煤矿公司有效股共16股,分别为ADRO、BSSR、BYAN、DOID、DSSA、FIRE、GEMS、iHRUM、INDY、iITMG、MBAP、MYOH、iPTRO、SMMT、iTOBA、BRMS;低效股共8股,分别为ARII、BOSS、BUMI、DEWA、GTBO、KKGI、PTBA、SMRU。
