How to add ESG factors to your portfolio? Positive/ Best-in-class screening

The best-in-class approach involves selecting top companies in terms of ESG metrics. These companies are actively making an effort to improve their ESG impact. Best-in-class screening rewards them by overweighting these companies in their portfolios. 

This method has the advantage of including companies that operate in industries that are not necessarily ESG-friendly. To illustrate, the energy sector is one of the worst sectors for sustainable investment due to its devastating effects on the environment. The energy sector represents 10.2% of the total nominal gross domestic product in Canada and represents over 12% of the S&P/TSX Composite Index as of March 31, 2021. Excluding this sector would mean a substantial deviation from the main Canadian market index. Positive screening also has the benefit of encouraging companies to adopt better ESG guidelines because that would make them more competitive compared to their peers. 

However, implementing a best-in-class screen is time-consuming, if done without the use of third party ESG ratings. Analysts must examine each company in the universe and rank them in terms of sustainability. Third party such as Sustainalytics, offered by InoAdvisor as an add-on, can considerably improve this tedious process. We provide a breakdown of the ESG Risk Rating, Notable Material ESG Issues, Product Involvement and a list of Controversies on over 12,000 companies worldwide. 


Best-in-class selection can be done on an absolute basis, when companies are selected based on their outperformance in terms of ESG characteristics in the entire universe, or on a relative basis, when companies are compared to their competitors within the same industry/sector and are selected based on their superior ESG ratings. 

We focus on the relative basis as it is the most used method. The steps are as follows: 

1. Assign an ESG rating to each company in the investible universe

Each company
has to be analyzed and assigned an ESG score in order to compare companies across sectors or industries and determine which ones are the best in terms of ESG performance. An alternative to this lengthy process is to use readily available ESG data providers.

2. Rank the stocks from best to worst in each sector

Classify the companies in each sector or indus
try from best ESG scored companies to worst ESG scored companies.

3. Overweight the ESG leaders and underweight the ESG losers in your portfolio

Depending on your strategy, you can overweight top ESG companies and underweight bottom ESG companies or only include top ESG companies in your po
