Common questions

Why do telecommunications companies often carry a lot of debt?

Building and upgrading networks takes large upfront spending, and many telecom companies borrow to pay for it. That is why debt-to-equity is a useful figure to check, with higher values meaning heavier reliance on borrowing.

What does Marvin's Overall score tell me?

It summarizes how a company compares with others in its industry today, drawing on Quality and Opportunity. It describes the present and does not predict future returns.

Why are some figures missing for certain stocks?

Marvin only shows a figure when the data is available for that company. Where a debt, margin or cash flow figure is missing, treat the picture as incomplete and look at the company's own financial reports.
