About Silicon Floor

Silicon Floor is a free terminal that tracks 207 listed companies across the AI and semiconductor supply chain — chips, interconnect, optics, memory, servers, power, neoclouds, equipment, AI software and the cloud giants — in one place, with the same figures for everyone.

Where the numbers come from

Prices refresh every minute during US hours. Fundamentals are read straight from SEC XBRL filings, not from a data vendor's summary. Institutional ownership is rebuilt from Schedule 13D/G and Form 13F; insider activity from Form 4; short volume from FINRA; dividends from payments observed in the tape.

What it will not do

Every figure carries the date of the data it comes from, not the date it was read. Nothing is estimated or interpolated: what is unknown is shown as unknown. Ownership is published as two bounds rather than one false number, because two managers can declare the same shares without it being possible to tell. Figures filed in a currency other than the quote currency are shown without derived ratios. A foreign issuer that files once a year is labelled as reporting a fiscal year, never presented as trailing twelve months.

Silicon Floor is a tracking tool, not investment advice, and it is not a licensed advisor.
