BOTT aims to track an index consisting of companies specializing in robotics and automation solutions for industrial use. This includes sectors like factory automation equipment, semiconductors, programmable logic and industrial machine parts. To be considered for inclusion, companies must adhere to several criteria, such as being listed on an exchange in a developed country, meeting minimum market capitalization and average daily value traded thresholds, and having a significant portion of their revenue tied to robotics and automation. The selection process considers factors like positive total return over the past 12 months and market capitalization ranking, resulting in the top 30 firms being included in the index. These companies, equally weighted, represent a mix of mid-sized to large corporations, with a cap of nine companies per industry to ensure diversity. Furthermore, the index undergoes review and adjustment every quarter, taking place on the first Fridays of January, April, July, and October.
