Market values are weekly snapshots in US dollars, not live quotes. Non-US listings are converted at approximate spot rates. A row shows its own date when its quote is older than the snapshot.

Treemap tiles are sized by market value within the tier. Row bars are scaled to the largest company in that layer, so they compare companies within a layer, not across layers.

Week change uses the local-currency share price where both weeks have one, otherwise the USD market cap, and only where this week's quote is newer than last week's; a row whose delayed quote has not changed shows no move. Forward P/E is as published by the quote source; it is not meaningful for REITs or loss-making companies.

Coverage is a representative set of public companies per layer, not an index. Private labs (OpenAI, Anthropic, xAI) appear in the log when they move the chain, not in the table. Nothing here is investment advice.
