Following the contribution of Mr. Mathieu LAMIEN entitled "The BRVM facing COVID-19" published on August 17, 2020, we provide the following clarifications on the variation of the indices.
The WAEMU Regional Stock Exchange (BRVM) notes that this contribution has a number of errors:

The decline in the BRVM Composite index over the period from March to August 14 is 12.27% and not 17% as indicated; The indices for the Agriculture and Public Services sectors fell by 25.7% and 15.9% respectively, not by 32% and 21%;

 
In addition, the article refers to the "services" sector, the correct name is "Public Services"; The fall recorded by the benchmarks on 18 May 2020 is due to the detachment of the dividend from sonatel shares during the same session and not to the publication of the Notice on compliance with the dissemination of financial information by listed companies; The opinion in question was, moreover, published by the BRVM and not by the "Autorité du marché financier (AMF)" as indicated in the article.
