The expected rate of return of the portfolio can be calculated using the risk-free rate of return, market risk premium and beta of the portfolio as shown below. First, we need to find out individual holding period returns: $$ \text{Holding period return}\ (\text{A})=\frac{\text{28}-\text{30}+\text{1}}{\text{30}}=-\text{3.33%}\ $$eval(ez_write_tag([[580,400],'xplaind_com-box-4','ezslot_1',107,'0','0'])); $$ \text{Holding period return}\ (\text{B})=\frac{\text{65}-\text{55}+\text{2}}{\text{55}}=\text{21.82%}\ $$, $$ \text{Holding period return}\ (\text{C})=\frac{\text{140}-\text{125}+\text{5}}{\text{125}}=\text{16%}\ $$. Alpha is used to determine by how much the realized return of the portfolio varies from the required return, as determined by CAPM. There is no easy way to determine the cause of a negative alpha without digging deeper into the situation.

$$ \alpha\ =\ \text{R} _ \text{p}-\ (\text{r} _ \text{f}+\beta\times(\text{r} _ \text{m}-\text{r} _ \text{f})) $$.
