Previous research finds that machine learning methods predict short-term return variation in the cross-section of stocks, even when these methods do not impose strict economic restrictions. However, without such restrictions, the models' predictions fail to generalize in a number of important...

This essay explores the link between the exponential probability density function and the present value function coupled with moment theory to derive important non probabilistic parameters from the Present value function in which are then used to derive a measure of the volatility of interest...

We identify a component of monetary policy news that is extracted from high-frequency changes in risky asset prices. These surprises, which we call "risk shifts", are uncorrelated, and therefore complementary, to risk-free rate surprises. We show that (i) risk shifts capture the lion's share of...

In this paper we apply Random Matrix Theory (RMT) to study daily returns correlations of 83 companies that are part of the Chilean stock market during the period 2000 to 2011. We find that using RMT to identify statistically significant correlations within our sample of stocks significantly...

Returns merely based on one purchasing price of an asset are uninformative for people regularly contributing to their old-age provision. Here, each purchase has an influence on the outcome. Still, they are commonly used in finance literature, giving an overly optimistic view of expected...

This paper considers a link between momentum profitability and firm ratings. Credit risks for naïve momentum strategies present a U-shaped pattern across momentum portfolios. Due to firms ratings containing valuable information and predicting the cross-sectional stock returns, firm ratings...

This paper analytically solves a heterogeneous agent model with idiosyncratic shocks to marginal utility of consumption and explores the effects of the borrowing constraint on the price of the asset, the composition of borrowers and lenders in the credit market, and wealth inequality. Results...

In 2008, the S&P 500 experienced a drawdown of about 50% from peak to trough. Many assets which are typically considered effective equity diversifiers also faced precipitous losses. In stark contrast, volatility levels as measured by VIX experienced significant increases and in 2008 repeatedly...

This paper investigates mean reversion properties of real effective exchange rates (REERs) using a semi-parametric quantile autoregression approach. This method accounts for non-normality and captures asymmetric and dynamic adjustments towards the REER's long run equilibrium, conditional on the...

The specter of rising interest rates in the US has caused many to consider the impact this will have on the traditional “anchor” to the portfolio: US Treasury bonds. From a mathematical point of view, rising interest rates unambiguously reduce the value of long duration bond holdings,...
