HOOD — Nasdaq-100 index addition

The company is classified in Financials in this dataset. The same ticker also appears in the tracked S&P 500 addition register. That record alone does not establish a transfer between indexes.

In the 30 calendar days leading into the effective close, HOOD moved +9.5%. The median 30-day run-up among the 14 Nasdaq-100 entries with a recorded announcement and prices for that interval was +12.2%; this stock was 2.8 percentage points below that median.
