Answer:
Yes, you can be confident that the portfolio will not lose more than 30% of its value next year
Step-by-step explanation:
In this question , the average return of portfolio is 12.5% and the standard deviation is 19.5%. It is estimated that there will be 30% loss next year. The confidence interval is 95%.
Range = Average return ± 2 x Standard deviation Low aid = 12.5% - (2 x19.5%) =12.5% -39% = -26.5%
High end = 12.5% +(2 x19.5%) =12.5%+39% = 51.5%
Thus, the low end is
26.5%
The range of return at 95% confidence interval is -26.5% to 51.5%
