The cost of equity can be calculated using the Capital Asset Pricing Model (CAPM), which is given by the formula:
\[ \text{Cost of Equity} = \text{Risk-Free Rate} + \beta \times \text{Market Risk Premium} \]
Where:
- \(\text{Risk-Free Rate}\) = 1.68%
- \(\beta\) = 1.39
- \(\text{Market Risk Premium}\) = 6%
Now, substituting the values into the formula:
\[ \text{Cost of Equity} = 1.68% + 1.39 \times 6% \]
Calculating the market risk premium component:
\[ 1.39 \times 6% = 8.34% \]
Now add this to the risk-free rate:
\[ \text{Cost of Equity} = 1.68% + 8.34% = 10.02% \]
Therefore, the cost of equity for the stock is 10.02%.
