If we use R to denote the unlevered raw return, then fR is the levered raw return, where f is the leverage. Hence the log return per period of a levered portfolio is log(1+fR). The expected log return is therefore just the average of log(1+fR) over many periods, which is also called the expected compounded growth rate.<br /><br />ErnieErnie Chanhttp://www.blogger.com/profile/02747099358519893177noreply@blogger.comtag:blogger.com,1999:blog-35364652.post-83188399711293992772015-09-20T22:14:21.161-04:002015-09-20T22:14:21.161-04:00Hi Ernie,
