Statistics used was  multiple regression for aggregated analysis and individual analysis. The results of hypothesis testing revealed that accounting-based risk factor and maeketing-based risk factor  provided a different effects. In regards to explanatory power, accounting-based risk factor can explained return on asset at R2 16.98 percent and increased to 18.55 percent after adding marketing-based risk factor and reverse results for marketing-based risk factor. This reflected that   accounting-base risk factor was not enough to explain firms’ accounting and marketing return. Depth insight, debt ratio played a key role on return on assets at the statistical significance 0.01. Howler, debt ratio provided negative relation. VaR had a positive relation to market-based returns at the statistical significance 0.01, which was consistent with capital asset pricing model theory.
