CitiBank's take on CAPEX announcement strategies using RavenPack data

By Peter Hafez, Chief Data Scientist, RavenPack

Recently, Citigroup’s Equity Research team published an interesting report on how investors can profit from CAPEX announcements . As a source for announcement data, they considered RavenPack’s event data that is automatically extracted from textual news and blogs using Natural Language Processing (NLP).

Empirical evidence suggests high reported CAPEX firms experience poor future stock returns. Explanations range from management empire building (over investment) to investors over-reacting, to past growth. In their report, Citi proposes an alternative explanation. They argue that such strategies have more in common with Value than with Growth Investment. Furthermore, they suggest that reported CAPEX results in poor future performance because it is a lagging variable. CAPEX often takes years to complete with fundamental investors being well aware of possible management reinvestment before the information finds its way into financial statements.
