Nasdaq-100 inclusion and deletion projection

The Nasdaq-100 is rebuilt from a published ranking with no committee step, so this page reproduces that rule rather than guessing at an outcome. Every company we track is tested against the index's eligibility rules one at a time, the ones that clear them are ranked exactly as the methodology ranks them, and the ranking says who would be inside the index and who outside it on today's figures.

The figures come from primary sources: company market value and liquidity from settled closing prices and volumes, earnings and public float from the company's own SEC filings, and listing exchange and industry classification from the filings too. Every rule on every card shows the figure it was judged on and the bar it was judged against, so a verdict can be checked rather than trusted.

A rule reports one of four outcomes, and the difference between the last two is the whole point. Pass means the figure was read and it clears the bar. Fail means the figure was read and it does not. Not evaluated means a figure the rule needs could not be read, which is a fact about our data and not about the company, so no verdict is reached at all. Not applied means the rule exists in the methodology and we have no way to test it, so it is named on the page and left out of the verdict rather than quietly counted as passed.

The first list is where today's ranking puts non-members inside the Nasdaq-100, and the second is where it puts current members outside it. A member leaving because it is being lifted into a larger index in the same family is shown separately from one dropping out, because those are opposite events.

A ranked index has a fixed number of places, so a company we could not measure still occupies one. A non-member is published as joining only when its rank would keep it inside the index even if every unmeasured member outranked it. That is why a company can clear every rule and still not appear on this page, and it is why these lists get longer as the underlying data improves rather than shorter.

The full reconstitution runs each December against the ranking published in the methodology. The March, June and September rebalances remove members that have fallen outside the top 125 by market value, and a company large enough to rank inside the top 40 can enter between reconstitutions on an expedited basis.

Scoring runs once per Eastern trading day, from settled closing prices and the filings on file that morning. Every model revision is immutable, so a new model may append a higher revision for that trading day without erasing what the earlier model said. Readers use the highest revision, while every published answer remains available for grading.
