Hong Kong s=22.24, CV = 2.383

Singapoure s=19.2, CV = 2.065

As measured both by standard deviation and CV, Hong Kong market was riskier than the Singapore market. The standard deviation of Hong Kong returns was (22.4 − 19.2)/19.2 = 0.167 or about 17 percent larger than Singapore returns, compared with a difference in the CV of (2.383 − 2.065)/2.065 = 0.154 or about 15 percent. Thus, the CVs reveal slightly less difference between Hong Kong and Singapore return variability than that suggested by the standard deviations alone.
