The evaluation of quantiles (or VaR, Value at Risk) and that of CVaR, Conditional Value at Risk in risk management (or mean excess in actuarial sciences) is a very crucial point in the decision processes. Indeed, there are often great difficulties (or impossibilities) in finding the kind of...

We derive an expression for the lifetime ruin probability (LRP), defined as the probability a fixed consumption plan will deplete an investment portfolio prior to a retiree's stochastic time of death, assuming the investment return driving the portfolio obeys a jump-diffusion process. This is in...

Time series momentum or trend following strategies have grown in popularity among institutional investors, with over $300 billion assets under management in managed futures strategies. A portfolio approach on recent return history of 60 liquid futures across different asset classes shows that...

We consider two forms of volatility weighting (own volatility and underlying asset volatility) applied to cross-sectional and time-series momentum strategies. We present some simple theoretical results for the Sharpe ratios of weighted strategies and show empirical results for momentum...

Motivated by studies of the impact of frictions on asset prices, we examine the effect of key components of time-series momentum strategies on turnover and performance. We show that more efficient volatility estimation and price trend detection can significantly reduce portfolio turnover by more...

In studies of time series momentum (TSM), the Newey-West t-test has size distortion for linear predictive regression with excess returns because of non-stationarity, endogeneity due to correlated errors, and a lack of finite moments due to heavy tails. To solve these problems, we propose a new...

The growing adoption of factor investing simultaneously prompted the active topic of factor timing approaches for the dynamic allocation of multi-factor portfolios. The trend represents a natural development of filling the gap between passive and active management. The paper addresses this...

We investigate whether long-term and short-term components of typical conditioning variables in asset pricing studies, such as the dividend yield or yield spread, have different implications for optimal asset allocation. We argue that short-term components relate mostly to momentum, and...

Paper studies the Momentum and mean reversion phenomena in the US markets. On the basis of listing in S&P 100 index, 100 stocks are undertaken for analysis. CLHL ratio helps to identify the stocks for the formation of the desired portfolios. CLHL ratio is calculated on the basis of closing...

Motivated by experimental findings and the literature on modular brain functions, we simulate the intertemporal decisions of consumers affected by temptation. In this framework, the lack of self-control distorts agents choices and reduces their wellbeing. While their consumption behaviour is...
