Not interested in any investment opinions. I want a list of who owns who of the biggest companies. I do not care of their success, past or future. Dig deep at the Rand Corporation for their research on topic. Reach out to the Swiss Institute of Technology and see if they have an update report. Email the three pHD's that wrote the report I pointed you to: "The Network of Global Corporate Control" authored by - Stefania Vitali, James B. Glattfelder, and Stefano Battiston. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3202517/
