How to Deal With Missing Financial Data

25.February 2023

The problem of missing financial data is widespread yet often overlooked. An interesting insight into the structure of missing financial data provides a novel research paper by authors Bryzgalova et al. (2022). Firstly, examining the dataset of the 45 most popular characteristics in asset pricing, the authors found that missing data is frequent among almost any characteristic and affects all kinds of firms – small, large, young, mature, profitable, or in financial distress. The requirement of multiple characteristics simultaneously makes the problem even worse. Moreover, the data is not missing randomly; missing values clusters both cross-sectionally and over time. This may lead to a selection bias, making most famous ad-hoc approaches like the median invalid. Considering the abovementioned findings, the authors propose a novel imputation method based on Principal Component Analysis (PCA).

Evaluating Long-Term Performance of Equities, Bonds, and Commodities Relative to Strength of the US Dollar

10.February 2023

The US dollar is the world’s primary reserve currency, is the most widely traded currency in the world (making up over 85% of all foreign exchange transactions), and is used as the benchmark currency for pricing many commodities such as oil and gold.
