An advanced discoverability tool for unstructured content to identify key drivers of equity performance, and changes in outlook over time.
Problem and opportunity
The buy-side spends millions of staff hours combing through unstructured text to drive asset management and investment decisions.
The problem can be illustrated by a buy-side equity analyst covering Amazon.
In a 90-day period, the analyst typically receives over 200 research reports about Amazon, with each report from two to 60 pages in length. On top of this, the analyst will also come across more than 50 company transcripts and filings, as well as hundreds of news stories and emails regarding Amazon.
This is just one of over 50 equities the analyst is covering. A clear case of information overload.
There is a distinct need to make it easier and quicker to understand and extract insights from text-heavy unstructured content.
Refinitiv Labs created SentiMine to help customers gain more value from unstructured content by reducing the time and associated cost of consuming research.
SentiMine combines natural language processing (NLP), sentiment analysis and deep learning to provide insights from thousands of unstructured research reports and company transcripts quickly and efficiently.
- Potential drivers of equity performance
- Changes in analysts’ outlooks (or sentiment) over time and across themes in equity research reports
- Changes in analysts’ and companies’ outlooks over time across themes in multiple transcripts
- Contrarian analyst views in a sea of consensus views
Refinitiv Labs created an ontology of potential drivers of equity performance that analysts look for when consuming equity research reports and transcripts. These potential drivers are referred to as themes. A supervised machine learning model identifies key themes in unstructured text.
The SentiMine engine currently accounts for 110 themes that affect all equities. Each theme falls into one of seven categories: accounting, business drivers, valuation, economics, management change, key risks, and ESG issues.
It also covers 40 themes across business sectors including finance, consumer retail, telecommunications, and technology.
This [SentiMine] is incredible. You have built this so fast. Just few weeks ago we were talking with a PowerPoint. The interface is incredible!
SentiMine in action
The SentiMine prototype includes over 907 tickers / 478 equities and 3 years of research reports and transcripts from 2017 to today. New research reports and transcripts are added on a daily basis.
The prototype includes:
- A thematic overview that breaks down hundreds of reports and transcripts by key themes and provides an analyst’s or company’s outlook (sentiment) for each theme
- A deep dive capability that surfaces every sentence from a report or transcript that contains the theme being investigated; helping to understand the analyst’s outlook
- A change in outlook highlights an analyst’s or company’s outlook on a specific theme over time, as well as comparing the outlook to the stock market price and mean target price
- A functionality to move between content classes, in this case equity research reports and transcripts
- An equity overview that provides a summary of the equity from both research reports and transcripts, as well as a peer analysis
