about

If your portfolio was one company, what would its P/E and P/S be?

Fund P/E figures published by issuers are often simplified.

One major issuer describes portfolio P/E as the weighted average price/earnings ratio of the stocks it holds.

This approach can exclude loss-making companies, causing the reported P/E to appear lower and the portfolio to look more attractively valued than when all holdings’ signed earnings are combined.

ratio/fox treats each ETF, mutual fund, or portfolio as one large conglomerate made up of its holdings. It combines their market values, signed earnings, and sales before calculating P/E and P/S. Loss-making companies reduce total earnings, while missing inputs reduce the reported coverage rather than being treated as zero.

The result is a consistent look-through valuation of the entire basket, with trailing and latest-quarter run-rate figures shown separately.

Public research pages may be cached for up to five minutes, so a newly published price or filing can take that long to appear.

How much of each company do you really own?

A company may appear in several ETFs and mutual funds while also being held directly. ratio/fox looks through every route, calculates each effective position, and combines matching companies. Instead of separate line items, you see your total exposure to the underlying company.

How much of one fund do you already own through another?

Every ETF and mutual-fund page ranks the 25 most similar funds by shared portfolio weight. Matching companies and explicitly reported same-currency cash count toward overlap; unknown positions do not. See whether a new fund genuinely broadens your portfolio or mainly adds more of the companies you already own.

Which investments appear in public discovery?

Public API lists, browse pages, and sitemaps share the same research-ready universe. ETF and mutual-fund discovery requires an official holdings source and at least one disclosed holding. Stock discovery requires a positive locally supported market capitalisation. Direct detail lookups may still resolve identity-only audit rows; those pages show a clear unavailable state and are marked noindex until usable research data arrives.
