Our notes connect public source material with practical questions about investment and technology. Each separates the source facts, the analysis on this site and any illustrative calculations. They do not report EXAM portfolio performance or imply that the organisations cited endorse EXAM.
Costs: compare three fee structures
The same purchase and sale amounts can produce different net results. Reproduce the three hypothetical examples, then enter your own documented costs in the calculator.
AI: read beyond a benchmark score
An AI system benchmark is not a business valuation. Using MLPerf as a reference, the note separates measured performance from assumptions about customer demand and economics.
How to use these notes
Follow the original source and its scope before comparing numbers. Check the assumptions and limits of each example. Where the evidence ends, treat the remaining point as a question rather than an established fact. The notes support reading and discussion; they do not select an investment for you.
