Rocket Lab stock is taking a hit today. Why is RKLB stock falling?
What Is Driving Rocket Lab’s Recent Stock Movement?The stock’s recent spotlight has been tied to two big headlines: NASA’s June 25 selection of Rocket Lab for three Electron launches (PolSIR and TSIS-2) and the June 29 definitive agreement to acquire Iridium Communications in a cash-and-stock deal priced at $54 per share (enterprise value about $8.0 billion). The Iridium transaction is expected to close in mid-2027, and it’s framed as creating a vertically integrated space company that can design, build, launch and operate its own constellations.Rocket Lab’s June 25 NASA win also carried specific timing that traders have been leaning on: PolSIR is slated for two back-to-back Electron launches from New Zealand no earlier than June 2027, while TSIS-2 was booked to launch in just seven months from contract signing.Critical Technical Levels for RKLB StockFrom a trend perspective, RKLB is still up 144.29% over the past 12 months and remains above its longer-term baselines, trading 6.6% above the 100-day SMA ($89.08) and 24.8% above the 200-day SMA ($76.12). But the near-term tape has weakened: the stock is 6.2% below the 20-day SMA ($101.22) and 11.2% below the 50-day SMA ($107.03), and the 20-day SMA sitting below the 50-day SMA keeps the short-term trend tilted bearish.Momentum is also cooling: MACD is below its signal line and the histogram is negative, which typically means upside pressure is fading versus the prior upswing unless buyers can reclaim that baseline. In plain English, MACD compares faster and slower trend forces—when it’s below the signal line, rallies tend to struggle until momentum improves.Key turning points help frame the current range: the stock logged a swing high and a 52-week high in May ($151.00), then put in a swing low in April before breaking above resistance in June and later breaking below support in May. That sequence often produces choppy, two-sided trade as the market re-prices the "new information" (here, the NASA win and the Iridium tie-up) into a more stable trend.
