Decomposition of optimal dynamic portfolio choice with wealth-dependent utilities in incomplete markets

Li, Chenxu; Scaillet, Olivier; Shen, Yiwen - 2020

This paper provides a novel five-component decomposition of optimal dynamic portfolio choice. It reveals the simultaneous impacts from market incompleteness and wealth-dependent utilities. The decomposition leads to implementation via either closed-form solutions or Monte Carlo simulations. With...

Mortality risk and real optimal asset allocation for pension funds

Menoncin, Francesco; Scaillet, Olivier - Institut für Schweizerisches Bankwesen <Zürich>; … - 2003

We analyze the problem of real optimal asset allo cation for a p ensionfund maximising the exp ected CRRA utility of its real disp osable wealth.The ﬁnancial horizon of the analysis coincides with the random deathtime of a representative subscriber. We consider a very general settingwhere...

False discoveries in mutual fund performance : measuring luck in estimated alphas

Barras, Laurent; Scaillet, Olivier; Wermers, Russ - 2009 - This version: April 2009

This paper develops a simple technique that controls for ldquo;false discoveries,rdquo; or mutual funds that exhibit significant alphas by luck alone. Our approach precisely separates funds into (1) unskilled, (2) zero-alpha, and (3) skilled funds, even with dependencies in cross-fund estimated...

Spanning tests for Markowitz stochastic dominance

Arvanitis, Stelios; Scaillet, Olivier; Topaloglou, Nikolas - 2018 - Current draft: January 2018

Using properties of the cdf of a random variable defined as a saddle-type point of a real valued continuous stochastic process, we derive first-order asymptotic properties of tests for stochastic spanning w.r.t. a stochastic dominance relation. First, we define the concept of Markowitz...

Spanning analysis of stock market anomalies under prospect stochastic dominance

Arvanitis, Stelios; Scaillet, Olivier; Topaloglou, Nikolas - 2020 - This version: April 2020

We develop and implement methods for determining whether introducing new securities or relaxing investment constraints improves the investment opportunity set for prospect investors. We formulate a new testing procedure for prospect spanning for two nested portfolio sets based on subsampling and...

Market efficiency reloaded: why insider trades do not reveal exploitable information

Dickgiesser, Sebastian; Kaserer, Christoph - 2008

by a subset of stocks with high arbitrage risk as measured by their idiosyncratic volatility. This restrains arbitrageurs … from engaging in otherwise profitable and price-correcting trades. As arbitrage risk is positively related to a stock's bid … mainly be explained by the cost associated with risky arbitrage. Our findings provide evidence that the German stock market …

Market liquidity risk, the difficulty or cost of trading assets in crises, has been recognized as an important factor in risk management. Literature has already proposed several models to include liquidity risk in the standard Value-at-Risk framework. While theoretical comparisons between those...
