Evaluated the performance of classification and regression methods of predicting the market change.

How Headlines Change the Way We Think

Introduction

Headlines are vital in both capturing readers’ attention and in influencing their online reading experience of news. In fact, approximately six in ten people limit their reading to headlines only, without clicking on a link to the full article. Furthermore, there are many online spaces where headlines are the only visible part of the news article, for example, news feeds and social media.

Recently online news and social media data have been widely used in the financial market. Quants and modelers believe that these unstructured and non-traditional data should shed extra light on the prediction of the market.

Both classification and regression methods to predict the market change were applied. Finally, which method is better in terms of performance of signal-based trading was evaluated.

Dataset

In this project, historical news headlines from Reddit WorldNews Channel will be applied. All headlines are ranked by reddit users' votes, and only the top 25 headlines are considered for a single date. (Range: 2008-06-08 to 2016-07-01)

For stock data, Dow Jones Industrial Average (DJIA) is used to "prove the concept". (Range: 2008-08-08 to 2016-07-01).
