In this paper we will try to improve on the Modern Portfolio Theory (MPT) as developed by Markowitz (1952). As a first step, we combine the MPT model with generalized momentum (see Keller 2012) in order to arrive at a "tactical" MPT. In our second step, we will use the single index model (Elton,...

In 1952 Harry Markowitz put forth a solution to the portfolio selection process. He summarizes the stages and objectives with the following, “The process of selecting a portfolio may be divided into two stages. The first stage starts with observation and experience and ends with beliefs about...

In this paper, we will first discuss the theories in financial economics we have been developed. We will then theories on financial econometrics and statistics we have been developed. Thereafter, we will discuss the applications of financial economic theories and financial econometric theories...

The Modern Portfolio Theory (MPT) has been the cornerstone of the asset allocation for over 40 years. In the past decade though, it led in a rather systematic way to bad investments decisions. One of MPT's main assumptions, investor risk aversion that translates into volatility aversion, biases...

Resilient Asset Allocation (RAA) is a more aggressive version of our Lethargic Asset Allocation (LAA) strategy. It combines a more robust “All Weather” portfolio with even slower growth-trend (GT) filter and a faster market crash-protection. GT timing goes risk-off only when both the US...

The aim of this work is to analyze the so-called "Low Risk Effect" and the evolution of the risk-reward relationship in time. Perhaps one of the milestones of the whole modern finance has been the investigation and the debate about the positive relationship between risk and reward in asset...

Volatility is usually considered as a synonym for risk. Mainstream financial theory states that higher portfolio volatility is translated into higher expected returns while diversification helps eliminate idiosyncratic risks. This leaves us with an apparent anomaly as low-risk (low-beta) stocks...

We examine in this paper the training and test set performance of several equity factor models with a dataset of 20 years of data, 1,200 stocks and 100 factors. First, we examine several models to forecast expected returns, which can be used as baselines for more complex models: linear...

In this paper we estimated IBM beta from 2000 to 2013, then using differential equation mathematical formula we split up the annual beta’s change attributed to the volatility market effect, the stock volatility effect, the correlation effect and the jointly effect of these variables.

The relationship between prices of paintings at public auctions and their attributes has received much attention in recent years. However, the effects of color have been mostly absent from these studies. The present study explored the relationship between price and color in Rothko’s post 1950...
