Common questions

What does Marvin's Overall score mean?

The Overall score runs from 0 to 100 and summarizes how a company compares with others in its industry today. Marvin's quality and opportunity scores feed into it. It describes the present and is not a forecast.

Does a higher rank mean a better investment?

No. The rank shows how a company scores against other device makers on Marvin's measures. It does not say whether a stock will do well, and it is not advice. Two companies with similar scores can have very different strengths, such as fast growth versus high margins.

Why do some stocks have no debt figure or free cash flow figure?

Marvin only shows a figure when the data is available for that company. Where a debt-to-equity ratio or free cash flow margin is missing, the blurb leaves it out, and you may want to check the company's own financial reports.
