How Finance Uses Natural Language Processing

Eight case studies in Banking and Investment Management

Crunching text is the new financial frontier

Natural Language Processing (NLP) is a collective name for a set of techniques for machines to uncover the structure within text data. 

Modern banks and investment managers have built their business on crunching numbers. But, with access to information no longer the competitive edge it once was, pockets of value have become much scarcer. Large volumes of text have become the new frontier for hidden market signals.

Moreover, growing volumes of text information is overwhelming employees.  It’s also becoming harder to keep handling text data with the same processes.

Research Outline

The research aimed to educate financial industry insiders on the world of possibilities that NLP now offers. FinText decided to tell this story through powerful case studies showing the different ways NLP was being put to use in large financial companies – and generating tangible rewards.

The report also explains key NLP and machine learning concepts (Topic Modelling, Named-Entity Recognition, Feature Selection etc.), assuming no prior knowledge.

Finally, the research introduced some of FinText’s use of NLP, applying text analytics to improve the processes of creating effective marketing for financial products.


FinText’s writers researched and wrote a series of case studies. Initially, these were published as gated content, but we’ve since made the information publicly accessible.

FinText Improves Investment Marketing with Text Analytics

How should companies improve their written marketing so it becomes more effective? How do they know what needs to change?

Text analytics looks at the underlying properties in volumes of texts. They’re a full reflection of a company’s content-creation process: how much, who writes, on which topics…text analytics not only reveals these properties, but helps teams improve.

Using data, we help clients measure and tweak their content process to align with what their clients enjoy. The right content builds trust and relationship, resulting in more business.


1.Media Coverage

The topic’s appeal won the report meaningful media coverage in leading industry publications. Most notably, in Institutional Investor, which wrote:

Asset managers seeking an edge in the uncertainty of the pandemic might do well to turn to natural language processing the way firms including American Century Investments do — and avoid the task of digesting massive volumes of research, according to text analytics company FinText.

In a recent paper looking at the ways finance firms uses the machine learning application, FinText said American Century tries to detect deception in management language during companies’ quarterly-earnings calls. Its sentiment model checks for omission of important disclosures, spin, obfuscation, and blame.

Firms such as Barings Asset Management, State Street Corp., and Deutsche Bank are also using natural language processing, according to the paper. The technology removes “text-related grunt work, allowing employees to focus on higher-value tasks,” FinText said in the paper.

2. Establishing the ‘NLP in Financial Services’ content niche

Prior to this report, AI or machine learning in financial services were already hot topics, but NLP in financial services had yet to emerge as a theme. But interest has been consistently growing.

A companion article to this research was published in established machine-learning journal Towards Data Science. For over two years, the article continues to attracts views daily, mostly through Google search.
