Stock themes and custom indexes
Thematic investing means building a portfolio around an idea, such as artificial intelligence, nuclear power or gold, rather than around a whole market. These are the 33 themes on Arithmos, with 211 public portfolios between them. Each portfolio is a custom index: a list of companies with a weight for each, which you can buy at your own broker.
