- Rocket Lab Corporation (NASDAQ:RKLB) dropped roughly 7.2% to $99.49 Monday afternoon. The stock lost ground even after it was added to the Nasdaq-100 ahead of the session.
- The index change is bringing in passive flows from funds tracking the Nasdaq-100. But weakness in SpaceX and a slide across space stocks put pressure on the trade.
- Rocket Lab has another lever: a $3 billion at-the-market and forward-sale program that lets the company add shares when demand is strong.
Rocket Lab Corporation (NASDAQ:RKLB) fell on Monday as the stock debuted in the Nasdaq-100. The move put RKLB at the center of a trade built on forced index buying, with the price pulled by the broad reset that’s hit space companies since SpaceX changed the sector’s tone.
Rocket Lab (NASDAQ:RKLB) shares traded at $99.49, down roughly 7.2%. The stock hit an intraday high at $107.37 and dropped to $96.56. More than 18.8 million shares changed hands by early afternoon in New York.
Nasdaq is set to add Rocket Lab to the Nasdaq-100 before the open on Monday, joining Astera Labs, CoreWeave, Nebius, and Teradyne. The change matters because the index is tracked by over 200 investment products with more than $800 billion in assets. Passive funds that follow the index need to buy into new names.
That move had a clear trigger. But Rocket Lab’s filings point to another factor not as widely watched.
Rocket Lab has a May prospectus that lets it sell up to $3 billion in common stock using an at-the-market, or ATM, program. That means shares could be sold right into the market at going prices. The same SEC filing allows for forward-sale deals too, with bank counterparties borrowing shares and selling them to hedge their risk. Rocket Lab said these hedge sales might push the stock price down or cap gains.
That helps explain the mixed trading. Index adds can mean new buyers, but they also make it easier for companies, banks or forward sellers to move stock in a liquid market. In other words: there’s a Nasdaq-100 bid here, but it’s not hard to find.
Rocket Lab kept up its top-line growth in the first quarter, posting revenue of $200.3 million, a 63.5% jump from a year ago. Gross margin was 38.2%. The company finished the quarter with $2.2 billion in backlog. For the second quarter, Rocket Lab guided to revenue between $225 million and $240 million. The company said its medium-lift Neutron rocket is still set for a debut launch later this year.
Rocket Lab CEO Sir Peter Beck called joining the Nasdaq-100 a “landmark moment” for the company, saying it signals a shift “from a small company with big ambitions to a global space leader.” Rocket Lab says it has completed over 80 launches and put more than 250 satellites in orbit. GlobeNewswire
Scarcity keeps driving Wall Street’s bull case. KeyBanc’s Michael Leshock and Liam Baker said last week the SpaceX debut selloff in space stocks was “unwarranted,” calling Rocket Lab the “clear #2 to SPCX” and pointing to demand for satellites, rockets and the company’s contract backlog.

SpaceX dropped 10.4% Monday, Firefly Aerospace slid 6.1% and Redwire was down 9.1%. The market didn’t buy the argument, so Rocket Lab’s slip ended up part of a sharp selloff across space stocks instead of looking like a lone reaction to its Nasdaq-100 entry.
But the risk is more straightforward now. Rocket Lab is still in the red on a GAAP basis, logging a first-quarter net loss of $45.0 million, and its valuation is tight if Neutron slips, launches slow, or new dilution comes in. If the company taps the stock’s index-driven liquidity to raise money, that would give the balance sheet a boost; for current holders, it also means more shares against the same short-term earnings base.
Rocket Lab is in the Nasdaq-100 for the rest of the week, but the market is still watching to see if index inclusion shifts who buys the stock once the main passive flows are done. On Monday, it hasn’t.
