How Nasdaq-100 additions work

Nasdaq reconstitutes the index annually in December, effective after the close on the third Friday. Quarterly weight updates also take effect on the third Friday of March, June and September. A change is announced first and only takes effect after the close on the effective date. Between those two dates, every fund tracking the index (QQQ, QQQM) has to buy the incoming stock, which is why the window matters to traders.

Of the 15 Nasdaq-100 additions with a recorded announcement date, the median notice between the announcement and the effective close is 10 days.

What happens to a stock after it joins Nasdaq-100

Inclusion is often described as a guaranteed pop. The tracked history is more mixed: the average stock ran up +19.1% in the 30 days into the effective close, then returned -2.9% in the first week (14% of additions were positive), -2.2% after one month, and +3.6% after a year. Returns are measured from the effective close and can also be viewed against the index itself, so a rising market doesn't get counted as an inclusion effect.

Best one-year outcome in this set: PLTR (Palantir Technologies) at +122.5%. Worst: TTD (The Trade Desk) at -61.7%.

When are Nasdaq-100 changes announced?

Annual reconstitution (December) + quarterly weight updates. Scheduled review, announcement and effective dates for the next twelve months are listed on the index review calendar. Ad hoc changes — a takeover, a bankruptcy, a fast-track promotion — are announced outside that schedule, usually with a few days' notice.
