TITLE: The Growth-Optimal Portfolio in Fund Models

ABSTRACT: This study concerns the estimation of the growth-optimal portfolio. The growth-optimal portfolio, or the numeraire portfolio, maximises the expected logarithmic growth rate and plays a fundamental role in portfolio choice and asset pricing. Efficient estimates of the growth-optimal portfolio under the CAPM and multi-fund models are derived. The accuracy of estimation is greater, the larger the variances of the returns. A measure of investors' economic loss caused by information loss due to missing data or unavailable observations is provided. In particular, the economic loss is larger, the larger the investment universe or the factors affecting asset returns. The estimate has a Bayesian interpretation. A shrinkage method targets maximal growth with the least amount of deviation of the growth rates.
