Why Does the Correlation between Stock and Bond Returns Vary Over Time?
Andersson, Magnus - 2011
the time-varying correlation between stock and bond returns. The results indicate that stock and bond prices move in the … same direction during periods of high inflation expectations, while epochs of negative stock-bond return correlation seem …, it is found that the stock-bond return correlation is virtually unaffected by economic growth expectations …

An estimator for the quadratic covariation of asynchronously observed Itô processes with noise : asymptotic distribution theory
Bibinger, Markus - 2011
The article is devoted to the nonparametric estimation of the quadratic covariation of non-synchronously observed Itô processes in an additive microstructure noise model. In a high-frequency setting, we aim at establishing an asymptotic distribution theory for a generalized multiscale estimator...

Asymptotics of asynchronicity
Bibinger, Markus - 2011
In this article we focus on estimating the quadratic covariation of continuous semimartingales from discrete observations that take place at asynchronous observation times. The Hayashi-Yoshida estimator serves as synchronized realized covolatility for that we give our own distinct illustration...

Expected Returns and Large Language Models
Jiang, Jingwen; Kelly, Bryan T.; Xiu, Dacheng - 2023
We extract contextualized representations of news text to predict returns using the state-of-the-art large language models in natural language processing. Unlike the traditional bag-of-words approach, the contextualized representation captures both the syntax and semantics of text, thus...

The Cross-Section of Individual Equity Option Returns
Shafaati, Mobina; Chance, Don M.; Brooks, Robert - 2022
This paper evaluates the underperformance of individual equity options relative to their replicating portfolios. Considering a high-dimensional set of variables, we use a machine learning approach to identify the characteristics of options and their underlying stocks that provide incremental...
