Mario Marin Fernandez
Mario Marin Fernandez is the owner and editor of Inversión Mensual and the person responsible for what is published on the site. Their details as owner are in the legal notice.
What they do on the site
- Decide which strategies are included and write the strategy pages and guides.
- Review each page against the primary sources (the book, the paper or the author's website) and note the date of the last review on it.
- Calculate each month's signal with the published rules, log it on the day of the close and make it available in the signal log.
- Handle error reports and publish corrections, as explained in the editorial policy.
What they are not
Inversión Mensual is an educational project. Its owner does not provide personalised financial advice and nothing published is a recommendation to buy or sell. If you need a decision about your money, consult a registered financial or tax adviser who knows your situation.
Interests and funding
The site displays advertising and currently has no affiliate links to brokers. The separation between that income and editorial content is described on the advertising and affiliates page.
Contact and corrections
