The headline is built from these numbers by fixed rules: a broad day when at least 70% of the companies that moved went the same way, a narrow day when the index went one way and most companies the other; flat when the Nasdaq 100 closed within ±0.10%. The sector order comes from the districts' changes.
Changes are the Mar 26 close against the Mar 25 close; after-hours trading is not included.
A building's width is proportional to the square root of the company's market value at the Mar 26 close (using today's share count): the square root keeps the gap of several hundred times between the largest and smallest company readable.
Districts are GICS sectors; sectors with fewer than five companies are grouped as Other Sectors. A district's change is its companies' average weighted by market value.
The indices are tracked through their funds (QQQ, SPY, DIA, IWM); changes are fund price changes, excluding dividends.
Breadth is counted with today's Nasdaq 100 member list; on a past day a few companies not yet in the index may be counted and departed ones left out.
