Do you show sector history or returns?

No. Combined market cap is a size snapshot. It can change because companies got larger or smaller, names crossed the floor, or the mix of constituents changed. That is not a cap-weighted or equal-weighted sector return, and we do not persist constituent dates.

Frequently asked questions

What is the Industrials sector?

Industrials groups manufacturers, machinery, aerospace, transport, and business-services companies under one industry-group label — a wide mix, not a factory index.

How are companies classified?

Each ranking row has one sector string from Financial Modeling Prep (GICS-style groups). MarketCapLens does not license GICS or remap those labels. A company belongs to one sector. Sectors with fewer than 3 companies above the $1B floor are omitted.

How is sector market cap calculated?

Sector market cap is the sum of each constituent company's market cap. A company's weight is its market cap divided by that sector total. Share of tracked market cap is this sector versus every company on MarketCapLens, including untagged names.
