This study examined the effect of Debt Equity Ratio (DER), Net Profit Margin (NPM), and Size on stock prices with company performance as measured by Return on Assets (ROA) as a mediating variable. The sample used is 136 manufacturing companies listed on the Indonesia Stock Exchange (IDX) in the 2014-2018 period. This research was tested using a Warp PLS statistical test tool to prove the proposed hypothesis. The results showed that DER has a significant negative effect on ROA and a significant positive effect on Stock Price. NPM has a significant positive effect on ROA as well as a significant positive effect on Stock Price. While Size has a significant positive effect on ROA but has no effect on Stock Price. ROA has a significant positive effect on Stock Price. ROA does not act as a mediating variable in the relationship between Size and Stock Price; however, ROA acts as a mediating variable in the DER and Stock Price relationship, as well as, in the relationship between NPM and Stock Price. The implications of the results of this study can be used by investors in making investment decisions, paying attention to the company's financial aspects, namely DER, NPM, Size, and ROA.

To investigate an effect of Gam-Roa tea on the free radical or alcohol detoxicating enzyme activities, the rats got a drink at the Gam-Roa tea instead of water for 3 months, and then the animals were sacrificed and obtained the following findings. The animals receiving Gam-Roa tea showed a decreasing tendency of hepatic xanthine oxithine oxidase activity and significantly incresed content of cytochrome P-450 compared with the control. Furthermore, hepatic superoxide dismutase and glutathione S-transferase activities were also more increased in rats received Gam-Roa tea than in the control group, those receiving water. On the other hand, alcohol or aldehyde dehydrogenase activities were more increased in rats receiving Gam-Roa tea than the control. In conclusion, it is likely that the liver of rats receiving Gam-Roa tea may have the oxygen free radical or alcohol detoxication potential.

The research aims to investigate the determinants of the financial performance of 1343 Vietnamese companies categorized into six different industries listed on the Vietnamese Stock Exchange over a four-year period from 2014 to 2017 using STATA software. Those determinants include firm size, liquidity, solvency, financial leverage, and financial adequacy while the financial performance is evaluated by three different ratios: return on assets (ROA), return on equity (ROE), and return on sales (ROS). The research results from these companies during the given period indicate that: (1) Firm size has a positive impact on both ROA and ROS, especially ROA but it has the opposite effect on ROE, (2) Adequacy ratio impacts positively on ROA and ROS but negatively on ROE, (3) Financial leverage considerably negative influences on ROE and ROS but positively impacts on ROA, (4) Liquidity has a positive effect on both ROA and ROE but a negative one on ROS and (5) Solvency has a positive impact on ROA and ROS but the negative impact on ROE. Furthermore, agriculture accounted for the highest percentage of profitability at the beginning, which was replaced by service for ROA but manufacture for ROE from 2016 to 2017 as opposed to the least in transportation.

A study was carried to compare two varieties of tall fescue(Festuca arundinacea Schr.): Fawn (endophyte infection) and Roa(endophyte-free). The study examined plant height, botanical composition, and dry matter yield of mixed pasture. The cattle grazed on a mixed pasture of tall fescue species and orchardgrass(Dactylis glomerata L.), perennial ryegrass(Lolium perenne L.) and white clover(Trifolium repens L.) during March 22, 1997, to September 21, 1997. The number of grazing animals was 4.3/ paddock(50m x50m) and was adjusted according to the condition of pasture. Dry matter yields determined on ungrazed pasture(7-time harvests) were 1,690 $\pm$407kg and 1,128 $\pm$ 238kg/ha on pastures consisting of Fawn and Roa, respectively. This difference was significant(P<0.01). There were 17.71 $\pm$ 1.27cm and 12.83$\pm$0.90cm in average plant lengths of Fawn and Roa(P<0.01), respectively The botanical composition of tall fescue and orchardgrass in the mixture treatment included in the Fawn variety were shown in 34.2 and 3.8％, comparing Roa with 17.1 and 9.6％, on the 21th of September, 1997, respectively. Tall fescue Roa represented a higher botanical composition than orchardgrass(a main species on Cheju). Crude protein content of Fawn was slightly less than that of Roa. From these results, we may conclude that Roa variety is nutritionally better, but is less adaptible to high temperature climate than Fawn. However, Roa variety is still better than orchardgrass in high temperature conditions.

The objective of this study was to establish whether global macroeconomic indicators affect the profitability of Korean shipping companies by using panel regression analysis. OROA (operating return on assets) and ROA (ratio of net profit to assets) were selected as proxy variables for profitability. OROA and ROA were used as dependent variables. The world GDP growth rate, interest rate, exchange rate, stock index, bunker price, freight, demand and supply of the world shipping market were set as independent variables. The size of the firm was added to the control variable. For small-sized firms, OROA was not affect by macroeconomic indicators. However, ROA was affected by variables such as interest rates, bunker prices, and size of firms. For medium-sized firms, OROA was affected by demand, supply, GDP, freight, and asset variables. However, macroeconomic indicators did not affect ROA. For large-sized firms, freight, GDP, and stock index (SCI; Shanghai Composite Index) have an effect on OROA. ROA was analyzed to be influenced by bunker price and SCI.

미국의 증권시장에서는 EVA가 주요한 주자지표로 주목을 받고 있다. 그동안 주요 투자지표로 사용되던 EPS, ROA, ROE, PER 등의 회계적 이익지표들에 비해 EVA의 활용도가 점차 높아지고 있다. 우리 나라에서도 투자지표로서, 경영관리지표로서의 활용 가능성에 대해 관심이 증가하고 있다. 본 연구에서는 우리 나라 주식시장에서 EVA가 유용한 투자지표로 활용될 수 있는가를 살펴보고자 하였다. 1991년부터 1995년의 분석기간에 걸쳐 첫째, 주당EVA가 회계적 이익지표보다 주식수익률을 더 잘 설명하는가, 둘째, 주당EVA가 높은 기업이 더 높은 초과수익률을 실현하는가, 셋째, 주당EVA는 개별 종목 초과수익률의 선행지표로 활용될 수 있는가를 EPS, ROA, ROE, PER 등의 회계적 이익지표와 비교하여 분석하였다. 분석결과 첫째, 우리 나라 주식시장에서 주식수익률은 주당EVA보다 회계적 이익지표인 EPS, ROA, ROE가 더 잘 설명하는 것으로 나타났다. 둘째, EPS, ROA, ROE를 기준으로 포트폴리오를 구성하는 경우 유의적인 초과수익률을 획득할 수 있는 것으로 나타난다. 주방EVA를 기준으로 포트폴리오를 구성하는 경우에는 3월 이후에 포트폴리오간 유의적인 초과수익률 차이가 발생하여 초과수익률 획득이 가능한 것으로 나타났다. 셋째, 주당EVA, EPS, ROA 등은 초과수익률에 대해 동행적 투자지표로 유용하고, ROE는 동행적 지표와 선행적 지표로 모두 유용하고, PER는 선행지표로 유용한 것으로 나타났다. 이와 같은 분석결과는 우리 나라 주식시장에서 EVA는 회계적 이익지표인 EPS, ROA, ROE, PER보다 더 우월한 투자지표라고 말하기는 어렵지만, 회계적 이익지표와 보완적으로 활용하는 경우에는 유용한 투자지표로 활용될 수 있음을 나타내고 있다.

The study aims to examine and analyze the factors that affect the return on assets (ROA) by placing net interest margin (NIM) as a moderating variable in influencing ROA. This research was conducted on 27 banks listed on the Indonesia Stock Exchange (IDX) for the period 2015 to 2018 with a total sample data of 91. The data used is a combination of time series data and cross-section data. The sampling technique used was the purposive sampling method. The data analysis technique used was path analysis with multiple regression analysis technique. The results of the analysis showed that the capital adequacy ratio (CAR) and loan to deposit ratio (LDR) have a positive but insignificant effect on ROA. NIM as a moderating variable does not influence the impact of CAR on ROA. However, NIM as a moderating variable is able to influence the impact of LDR on ROA. From the results of this study, it is evident that the LDR will increase the ROA at banks that generate high NIM.

This study comprehensively investigates whether there is an impact of risk, size, profitability, earnings per share, dividend yield, and book-to-market equity on the stock prices of Jordanian banks listed on the Amman Stock Exchange (ASE) for the period 2006-2018. To mitigate endogeneity concerns and to control for within-bank dynamics, panel data fixed effects estimations are used. This study shows that size (SIZE), profitability (ROA), dividend yield (DY) and book-to-market equity (BE/ME) ratios are statistically significant determinants of stock prices. The risk (RISK) factor measured by volatility of ROA has a positive and significant effect on the stock prices, while earnings per share has minimum influence on the stock prices. The results show that ROA has a significant and positive effect and provides the largest effect among all variables used in this study, while the RISK factor has a positive and significant effect. In contrast, SIZE, DY, and BE/ME have a significant negative effect on stock prices. The paper presented new evidence showing that ROA is a better determinant of stock prices in Jordanian banks, and RISK significantly affects stock prices. The researcher recommends using a factor of profitability represented by ROA which has a significant positive effect on the stock prices in Jordanian banks and applying the ROA variable to other sectors.

This study conducted correlation analysis and multiple regression analysis using financial statements, loan structure, ROA and ROA volatility of domestic commercial banks, regional banks and special banks for the past five years (2012 ~ 2016). The result is as follows. First, as a result of correlation analysis, bank's ROA is positively related to household loans and SME loans, but it is negatively correlated with the ratio of loans to large companies, sector bias, and loan loss provision ratio. Second, ROA volatility was negatively related to household loans and SME loans, but it was positively correlated with large corporate loans, sector bias ratio, and loan loss provision ratio. Third, as a result of the regression analysis, the variables that have a statistically significant effect on the ROA volatility of banks were household loans, SME loans, and large enterprise loans. From these empirical results, special banks with high volatility in profits need to diversify loan types and sectors in order to achieve business performance outside of policy finance. and Especially, Suhyup Bank and Nonghyup Bank, which have a large commercial role, have a large size per unit by focusing on short-term profit and Rather than focusing on large companies or large loans that are easy to obtain financial information, it is necessary to focus management capabilities on household loans and SME loans by developing capabilities such as screening techniques.
