AOT Software Platform ETF(AMEX:AOTS)

AOTS tracks an index of companies classified as software-driven enterprises, whose core business relies on software platforms and generates at least 20% of revenue from software-driven activities (cloud infrastructure, enterprise software, development tools, analytics/AI, middleware, industry solutions). Companies must have a positive Earnings to Price ratio to qualify. Selection is based on the average rank of a factor score (cost of goods sold/revenue, earnings/price, return on invested capital) and market cap, with the top 50 ranked firms and a 10-company buffer for incumbents. Weighting favors companies with over 50% software revenue, while those below are capped at 20%. Weights are float-adjusted, max 7.5%, min 0.5%, with over-5% weights keeping below 45% in total. The index is reconstituted and rebalanced on the third Friday of March, June, September, and December.
