Optimal stopping of expected profit and cost yields in an investment under uncertainty
expected profit cost yields investment under uncertainty
2010/10/18
We consider a finite horizon optimal stopping problem related to trade-off strategies between expected profit and cost cash-flows of an investment under uncertainty. The optimal problem is first formu...
Portfolio optimization when expected stock returns are determined by exposure to risk
1/n strategy Black–Scholes model expected stock returns Markowitz’ problem portfolio optimization ranks

It is widely recognized that when classical optimal strategies are applied with parameters estimated from data, the resulting portfolio weights are remarkably volatile and unstable over time.The predo...
Nonparametric Methods for Estimating Conditional VaR and Expected Shortfall
Bandwidth selection Boundary effects Coherent risk measurements Empirical likelihood Expected shortfall Local liner estimation Nonparametric smoothing Quantile regression Time series Value-at-risk Weighted double kernel

In this article we propose a new nonparametric estimation method to estimate the
conditional value-at-risk and expected shortfall functions based on the weighted double
kernel local linear estimator...
