Why Rocket Lab Stock (RKLB) Is Falling, and What the Alternative Data Says Next

By AltIndex Research · 13 min read · June 7, 2:33 pm

RKLB has fallen more than 23% in a week, and the timing has little to do with the company itself. The selloff is sector wide, triggered by a SpaceX IPO that stopped looking like free money. Underneath the price action, Rocket Lab's own data is the strongest it has ever been: a record quarter, a $2.2 billion backlog, and hiring at all-time highs.

Over the last twelve months, Rocket Lab stock is up roughly 280%, from about $29 last June to $110 today, one of the best runs on the entire market. Over the last seven days, it is down about 23%. Both of those things are true at the same time, and the gap between them is where the story lives.

The drop did not come from Rocket Lab. It came from SpaceX, Blue Origin, and a wave of profit-taking after a parabolic move. When the news broke that S&P would not fast-track a newly listed SpaceX into the S&P 500, the entire space sector deflated at once. The thesis that billions in passive index money would soon flood space-adjacent names lost its engine, and RKLB, as the most-owned pure-play launch stock on Reddit, took the brunt of it.

From Under $30 to $150 to $110 in Twelve Months

To understand the last week, you have to understand the last year. In June 2025, RKLB traded under $30. By late May, it touched an intraday peak above $150. That is a fivefold move in twelve months, fueled by a steady drumbeat of contract wins, a market-wide reappraisal of the space economy, and growing anticipation around the SpaceX IPO lifting every name in the sector.

A move that size does not unwind quietly. The chart below shows the full twelve-month price history alongside our AI Score for the stock. Watch what the AI Score does near the top: it never confirmed the final leg up.

AltIndex Price & AI Score Data

As RKLB ran from $80 to $150 between late April and late May, our AI Score drifted down into the high 50s and low 60s. The score blends fundamentals, hiring, customer signals, and audience data into a single 0 to 100 read. A score in the 60s lands in buy territory, but not skyrocket territory. The model was effectively saying that the price had run ahead of the signals supporting it. The pullback that followed brought price and signal back toward each other.

The Business Had Its Best Quarter Ever

In the company's most recent quarter, Rocket Lab reported record revenue of roughly $200 million, up about 63% year over year. Backlog crossed $2.2 billion, more than double the prior year, after the company signed 31 new Electron and HASTE launch contracts plus five dedicated Neutron missions, including the largest launch deal in its history. The U.S. Department of Defense placed a $190 million block order for 20 hypersonic test flights using the company's HASTE vehicle. None of that changed in the last week. The stock fell anyway.

AltIndex Quarterly Revenue Data

The catch is the bottom line. Rocket Lab is still losing money. The company posted a net loss of about $45 million last quarter, or seven cents per share. The good news for shareholders is that the loss is narrowing: it came in below the $60.6 million loss a year earlier and the $52.9 million loss the prior quarter, and adjusted EBITDA loss shrank to $11.8 million. The Neutron rocket, its medium-lift vehicle and the real key to competing for larger payloads, has not flown yet and carries heavy R&D and capex costs. This is a growth story with genuine execution risk, not a value stock. When you pay a premium multiple for a company that is not yet profitable, the price is sensitive to sentiment, and sentiment just turned.

What Actually Caused the Drop

Three things hit at once, and none of them were company specific.

First, the SpaceX catalyst broke. For months, investors bid up space names on the theory that a blockbuster SpaceX IPO would pull passive index money into the whole sector. When S&P Global signaled it would not change its rules to let a freshly listed SpaceX into the S&P 500 quickly, that theory lost its engine. The passive-buying tailwind investors were positioning for is now off the table for the near term.

Second, Blue Origin suffered a rocket explosion on the pad, which spooked the entire launch group and raised fresh questions about multi-vendor reliability across the sector. Sympathy selling does not care whose rocket it was.

Third, profit-taking. After a roughly 280% run over twelve months, large holders had every reason to lock in gains, and our data shows they did. We logged a steady stream of insider transactions through late May and early June, all on the sell side. A director sold 40,000 shares at around $124 in early June. Other executives trimmed positions in late May at prices between $143 and $150. Routine executives taking liquidity into strength is not a red flag by itself, but the clustering of sales right at the top added fuel to the reversal.

The analyst community reacted in real time. Our event feed captured a cascade of price-target cuts in the first week of June, including one firm dropping its target by more than 21% in a single revision. Wall Street did not abandon the stock, but it repriced the optimism fast.

Reddit Never Left

If you only watched the price, you would assume retail ran for the exits. The Reddit data says otherwise.

AltIndex Reddit Mentions Data

RKLB is one of the most discussed stocks on Reddit, and engagement spiked hard through May as the stock ran and again as it fell. We flagged a Reddit mentions spike of more than 130% on a single day in late May, and weekly mention volume sits near the highest levels we have recorded for the ticker. The conversation has shifted in tone, from "how high can this go" to debates about valuation, comparisons against AST SpaceMobile, and a lot of people asking whether this is the dip to buy. Falling price with rising chatter is a classic sign that retail is engaged rather than capitulating. That cuts both ways: engaged retail can put in a floor, or it can mean there is still a lot of emotional money left to shake out.

The Hiring Signal Points Up

The single most telling piece of alternative data is the one almost nobody looks at: hiring. Companies that are quietly pulling back tend to freeze headcount first. Rocket Lab is doing the opposite.

AltIndex Job Postings Data

Job postings are up about 15% month over month and sit at the high end of the last year, near 270 open roles a week. LinkedIn headcount has climbed steadily from roughly 1,820 employees last summer to about 2,200 now, a gain of more than 20% in under a year. These two data points show a company staffing up for Neutron and for the backlog it just signed. The employment outlook is the strongest signal in our model for this stock right now, and it is flashing expansion while the price flashes fear.

This is not the first time we have pointed to these signals. Back on April 1, with RKLB trading at $67.73, we published an article comparing Rocket Lab and Iridium and made the structural case for RKLB on exactly this data: 22% employee growth, Neutron-specific hiring running in parallel with commercial business development, and a backlog that was then $1.85 billion. The stock is up about 63% since. We also flagged the other side of the trade in that article, warning that RKLB was already pricing in substantial success, which limited the margin of safety. That caution is the part playing out this week. The thesis held. So did the risk.

The Bottom Line

Rocket Lab the business is executing better than it ever has. Rocket Lab the stock got ahead of itself and is now paying it back. Those are two separate facts, and the last week resolved the second one without touching the first.

So what does the alternative data say next? It points in two directions at once, and that is the honest read. The signals that matter for the long run, hiring at record highs, a doubling backlog, and a wave of new contract wins, are still pointed up, which is why our score has not fallen into sell territory despite a 23% weekly drop. But the signals that powered the rally, brand interest and sentiment, have cooled, and the SpaceX index trade that inflated the whole sector is gone. That combination usually means more volatility, not a clean bottom.

The one catalyst that could reset the story is Neutron. Rocket Lab has now targeted its first launch for the fourth quarter of 2026, after a tank-test setback earlier this year pushed the timeline. Until that rocket flies, RKLB remains a high-conviction bet on execution at a price that leaves little room for a stumble. For now, our data says watch, not chase. The retail crowd has not left, the company is still building, and the next real catalyst is sitting on a launch pad.
