We summarise conclusions drawn from an academic paper comparing Japanese CPI data with a Neudata listed alternative data provider in an attempt to evaluate the accuracy of official statistics vs a ‘true’ inflation measure. The authors conclude that 1) the Japanese CPI is a poor predictor of actual inflation when measured inflation is below c.2%, and 2) the US PCE deflator methodology is superior to the Japanese CPI methodology. We also evaluate several alternative Japanese data providers and recommend further academic reading on this topic.

This study attempts to analyse the effectiveness of using Twitter and Google to predict stock index returns across the US, UK, Canada and China by measuring the appearance of bullish or bearish terms across Twitter and Google Trends and subsequently creating a 'bullishness index'. We identify key findings and the alternative data providers that are relevant to this analysis.

With a popular corporate events data aggregator as the primary source of data for this study, the authors claim companies that advance their earnings announcements by 4 or more days exhibit positive earnings surprises, while firms that delay earnings announcements after previously announcing their release date are more likely to have negative earnings surprises. The authors suggest that companies delay their announcement date due to negative events.

We summarise key findings from an academic paper which attempts to show whether financial performance is positively related to environmental performance by studying alternative data across several hundred Japanese manufacturing firms.

In this study, data from a financial news provider was used to examine whether trading in extended hours is predictive of future returns for US stocks. Specifically, the data provider captured a given stock’s return from the time of the news item through to the end of the session.
