NEW YORK, June 20, 2026, 13:02 (EDT)
- Rocket Lab ended Thursday’s session at $107.24, off 0.69% for the day. Shares then fell to $106.20 after the bell. Nasdaq was closed Friday for Juneteenth.
- The stock ended up about 4.7% from last Friday’s close, getting a boost Monday after an analyst upgrade and some index inclusion trades.
- Rocket Lab will be added to the Nasdaq-100 on Monday before the open, putting the launch and space-systems firm into a key index used by over 200 investment products.
Rocket Lab is set to join the Nasdaq-100 on Monday. Shares ended the holiday-shortened week higher, despite tumbling on Thursday and pressure across new space stocks. Rocket Lab’s last close was $107.24. Some investors are asking how much of the expected index buying is already reflected in the stock.
Timing is key here. Rocket Lab is set to join the Nasdaq-100, which tracks bigger non-financial names on Nasdaq, ahead of the open on June 22. That move could push index funds—those that follow the benchmark instead of picking stocks—to hold the shares after the reshuffle.
Nasdaq said it will add Rocket Lab, along with Astera Labs, CoreWeave, Nebius and Teradyne. Charter Communications, Cognizant, Insmed, Verisk and Zscaler are out. Rocket Lab gets more market attention now, but joining the Nasdaq-100 comes with higher pressure. The index tends to draw new money, but it also can turn quickly if growth stocks slip.
Rocket Lab called it “a landmark moment.” Founder and CEO Sir Peter Beck said the inclusion showed the company’s shift “from a small company with big ambitions to a global space leader.” Rocket Lab said it has done more than 80 launches and put up over 250 satellites. It is also working on its medium-class Neutron rocket for constellation missions. GlobeNewswire
Rocket Lab’s shares swung sharply last week. The stock dropped 10.8% on Friday, then regained 6.7% on Monday. It lost 4.2% Tuesday, rebounded 3.2% Wednesday, and eased 0.7% Thursday. Trading was heavy Thursday, with about 70.3 million shares changing hands—more than double the daily volume of the previous three sessions. Traders appeared to be shifting positions ahead of the long weekend.
Wall Street had a hand in the shift. KeyBanc’s Michael Leshock bumped Rocket Lab up to Overweight, which signals the stock could outperform, and said the SpaceX-connected drop was “unwarranted,” MarketWatch reported. Firefly Aerospace also got an upgrade. Both moves came as analysts looked again at space stocks after SpaceX’s Nasdaq debut. MarketWatch
SpaceX is still dragging on the trade. Reuters said Thursday that SpaceX shares dropped over 6% as the post-IPO rush faded. Rocket Lab and Planet Labs also fell. Kat Liu, an analyst at IPOX Schuster, said “some degree of profit-taking is not surprising” after the offering’s size and quick start. Reuters
Insider filings landed late this week. According to a Form 4 with the Securities and Exchange Commission, Rocket Lab senior vice president and general counsel Arjun Kampani got rid of 88,000 shares at $107.98 each on June 18, moving them into an exchange fund, which can help diversify big stock positions. After the move, the filing says Kampani held 264,705 shares directly.
Rocket Lab’s latest numbers backed up its bullish case. The company said first-quarter revenue topped $200 million, and backlog ended the quarter at $2.2 billion—its total contracted work not yet booked as revenue. Rocket Lab also reported access to over $2 billion in liquidity, or available funding.
But there’s clear risk. A stock can win an index bid and still drop if traders think the good news is priced in. Rocket Lab is still in the high-expectation space trade. Delays with Neutron, softer launch demand, contract timing, insider selling headlines, or another SpaceX pullback could swing sentiment quickly. The new week kicks off with forced buying as the big story, but then execution needs to pick up the slack.
