Who is behind Arcarios

Arcarios is a finance media built on data, part of the Soverios group. We run our own screening engine, track our own portfolios against the major indexes with dividends reinvested, and publish the results with the method attached. When a number is ours, we say so and show how it was computed; when it is not, we link the source. We publish analysis, never advice: what you do with the numbers stays your decision. Read how our research is produced and what we will never tell you to do.
