Given the efficient set, investors shall choose according to their risk-return preference represented by a utility function, typically resulting an asset allocation choice in the form of linear combination between cash, which is riskless, and the ?optimal? combination of risky assets (Tobin, 1958.)This study looks at how different types of investors actually make their asset allocation decisions. Based on evidence obtained from private bankers who manages wealth for High Net Worth Individuals (HNWIs,) and private banking client classification in Chung (2014,) we found evidence which suggests that asset allocation decisions made by this group is rather different from that proposed in the literature.enAsset AllocationDiversificationInvestment DecisionsPortfolioPortfolio ChoicePrivate BankingPeer Reviewed Journal Article
