Mr$.$ James K$.$ Silber, an avid international investor, just sold a share of N$$stle$,$ a Swiss firm, for SF$5,130.$ The share was bought for SF$4,650$ a year ago. The exchange rate is SF$1\mathrm{.}85$ per U$.$S$.$ dollar now and was SF$1\mathrm{.}88$ per dollar a year ago. Mr$.$ Silber received SF$130$ as a cash dividend immediately before the share was sold. Suppose that Mr$.$ Silber sold SF$4,650,$ his principal investment amount, forward at the forward exchange rate of SF$1\mathrm{.}87$ per dollar. How would this affect the dollar rate of return on this Swiss stock investment?
