VaR_Delta-Normal fails in two counts: subadditivity and potentially producing losses larger than its portfolio value. This paper solves the second inconsistency developing formulas derived from a put option, named PVaR_Delta-Normal and Put_Expected_Shortfall, PSF_Delta-Normal; the latter also...

Leveraged ETFs provide a convenient mechanism to dynamically change portfolio exposure and can be successfully used to construct robust portfolios that perform well during equity market drops. We start with a classical 60 percent Bonds/ 40 percent Stocks portfolio with monthly rebalancing that...

We discuss performance of some known market anomalies like equal-weighted index, low volatility stock index, factor anomalies of Andrea Frazzini, Ronen Israel and Tobias J. Moskowitz. We suggest the utilization of these anomalies through dynamic risk allocation in portfolios based on these...

Cryptocurrencies have grown exponentially and gained increasing attention in recent years, and while it's true that it's secure by design, “Security” remains the cornerstone of any and all cryptoassets.To benchmark the global cryptocurrencies market from a security perspective, track current...

Leveraged ETFs provide a convenient mechanism to dynamically change portfolio exposure. A classical portfolio insurance strategy of Black-Jones-Perold can be easily implemented with leveraged ETFs. More complex dynamic portfolio strategies that also can be implemented using leveraged ETFs. We...

This study aims at analyzing the ability of managers of Alternative Risk Premia (ARP) portfolios to outperform benchmarks and to deliver alphas. Using a sample of more than 200 ARP indices, we first distinguish performance between allocation strategy and picking ability. Our first results show...

NWW Concept (North & all, 2009) determines the necessary threshold conditions for the transition from Limited Access Orders (LAO) to Open Access Orders (OAO). In this article, I offer a sufficient criterion for such a transition. What are the conditions under which a rent-seeking behavior...

Transaction cost, defined as implementation shortfall that is originally proposed by Perold (1988), is an important element in portfolio performance measurement. There are several factors visible or fixed (such as commission and taxes) and variable (that are invisible or indirectly affect cost...

Security indices are central to modern finance. Because corporate bonds trade infrequently – often less than once a month – corporate bond indices cannot rely exclusively on real time prices, and must instead estimate the value of the market portfolio. While commercial indices do this using...

This paper studies portfolio optimization through improvements of ex-ante conditional covariance estimates. We use the cross-section of stock returns over a 52-year sample to analyze trading performance by implementing the machine learning algorithm of hierarchical clustering. We find that...
