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.
Use the industry table for the split: aerospace and defense, machinery, railroads, trucking, and consulting or waste services are different businesses that happen to share this sector string. Combined cap is size, not an industrial production print.
MarketCapLens includes common equity listed on NASDAQ, NYSE, or AMEX that clears the $1B market-cap floor and is actively trading. ETFs, funds, preferred shares, equity units, and warrants are excluded. Dual share classes of the same company are counted once.
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.
