Abstract: We focus on discretionary portfolio management to examine the impact of advisory on strategic asset allocation and its dynamics. We use a unique and proprietary dataset from a large European private bank of 5,627 clients that covers the period from 2005 to 2013. While high-net-worth clients opt for customised advisory, we show instead that allocations are quite similar across a range of clients; advisors are conservative and favour low-risk profiles regardless of clients' age. We observe a low number of active clients and provide evidence of the low extra returns generated by changes in the portfolio asset allocation. Finally, we highlight that changes in risk attitude mainly depend on portfolios' past performance and/or past market performance, suggesting that advisors are not effective in mitigating extrapolation bias and self-attribution bias. Overall, we provide evidence of the low level of tailoring, suggesting a 'one size fits all' approach in private banking.
