Exercise $3-19$ Algo

The accompanying data file shows the annual returns $($in $\%)$ for a technology mutual fund and an energy mutual fund

over the past $37$ years.

b$.$ Which fund was riskier over this time period?

c$-1.$ Given a risk$-$free rate of $2\%,$ calculate the Sharpe ratio for each fund. What does this ratio imply?

Note: Round intermediate calculations to at least $4$ decimal places and final answers to $2$ decimal places.

c$-2.$ Over this time period, the Sharpe ratio implies that the:

Technology fund had a higher reward per unit of risk.

Energy fund had a higher reward per unit of risk.

Technology fund had the higher relative dispersion.

Energy fund had the lower relative dispersion.
