An equally-weighted portfolio contains eight securities, each with a standard deviation of returns of 50%. If the pairwise correlation of returns for these securities is 0.6, calculate the resulting portfolio's standard deviation of returns. Show all calculations.

Penske Ltd has a standard deviation of returns of 18% and a correlation with the market portfolio of 0.8.
