RT Journal Article SR Electronic T1 Instantaneous Mean-Variance Analysis of Bond Returns JF The Journal of Fixed Income FD Institutional Investor Journals SP 32 OP 39 DO 10.3905/jfi.2004.419551 VO 14 IS 1 A1 Haim Reisman A1 Gady Zohar YR 2004 UL https://pm-research.com/content/14/1/32.abstract AB An explicit formula for the instantaneous expected return of any bond can be used to determine the mean-variance efficient frontier of instantaneous bond returns. Fitting the model to historical U.S. Treasury quotes, the analysis anticipates very high Sharpe ratios. The empirical findings support this prediction.
