Although better information about the dynamics of the yields on financial assets is decisive for both borrowers and lenders alike, it is not uncommon, in the literature, for researchers to employ standard unit-root tests to determine the extent of the persistence, and based on such results,...

Based on a method developed by Leybourne, Kim and Taylor (2007) for detecting multiple changes in persistence, we test for changes in persistence in the dividend-price ratio of the NASDAQ stocks. The results confirm the existence of the so-called Dotcom bubble around the last turn of the century...

Expected returns and risk assessment are important issues when evaluating capital investment projects. We use VARX-MGARCH models and asset pricing theory to model the expected rate of return in Brazil, Colombia, Mexico and Peru for late 2006. The main objective of this paper is to present an...

When faced with an investment opportunity in commercial real estate, the investorrequires knowledge of the discount rate since it can be used to convert expected futurecash flows from the property in today's terms and in doing so, place a value on theproperty. The so-called required rate of...

We consider the randomness of market trade as the origin of price and return stochasticity. We look at time series of trade values and volumes as random variables during the averaging interval Δ and describe the dependences of market-based volatilities of price and return on the volatilities...

This paper presents probability distributions for price and returns random processes for averaging time interval Δ. These probabilities determine properties of price and returns volatility. We define statistical moments for price and returns random processes as functions of the costs and the...

The aim of this paper is to develop a hedging methodology for making a portfolio of options delta, vega and gamma neutral by taking positions in other available options, and simultaneously minimizing the net premium to be paid for the hedging. A quadratic programming solution for the problem is...

We show that the price and returns volatilities depend on the first and the second degree of the total values and the total volumes of the transactions aggregated during averaging time interval Δ. We derive expressions that describe price volatility via volatilities of the value and the volume...

The aim of this paper is to develop a hedging methodology for making a portfolio of options delta, vega and gamma neutral by taking positions in other available options, and simultaneously minimizing the net premium to be paid for the hedging. A quadratic programming solution for the problem is...

In this paper we update our 2006 white paper ldquo;A Quantitative Approach to Tactical Asset Allocationrdquo; with new data from the 2008-2012 period. How well did the purpose of the original paper ndash; to present a simple quantitative method that improves the risk-adjusted returns across...
