We studied how volatilities of earnings, operating incomes, and accruals effect on
the firm value in Korean capital market. In Korean capital market, volatilities of
earnings, operating incomes, and accruals effect on the firm value negatively, and this
result plays important roles to explain many corporate risk management activities.
Unlike the existing risk measures―systematic risk and idiosyncratic risk, these
volatilities is more useful since being calculated easily with financial statement.
The result, that investors have no preference of the low earnings volatility through
cash flow over that through accruals (non-cash flow), disagrees with results of
previous studies. These result needs to be verified in further studies
