Rocket Lab stock is moving in positive territory. Why are RKLB shares climbing?

What Is Driving Rocket Lab’s Stock Ahead of SpaceX IPO?The SpaceX IPO roadshow is wrapping up, with final pricing expected Thursday night and trading slated to begin Friday—timing that has been pulling incremental flows into "space proxy" names like Rocket Lab, Redwire, AST SpaceMobile and Intuitive Machines.SpaceX is targeting a $1.75 trillion valuation and plans to price shares at $135 while raising about $75 billion, a setup that's amplifying the "halo" bid in Rocket Lab and other listed proxies as traders position for the debut.Rocket Lab is also coming off a sharp run that peaked at an all-time high of $151.00 in May, and the stock has had to digest profit-taking plus insider selling of roughly $18 million (including a director's large sale in June).Rocket Lab's own fundamentals have helped keep buyers engaged: first-quarter revenue of $200.35 million beat the $189.68 million estimate and rose 63.5% year over year, reinforcing the idea that the move isn't purely sentiment-driven.U.S. index ETFs are trading higher in premarket, led by the Nasdaq up 0.92% and the S&P 500 up 0.51%, which is giving high-beta momentum names a tailwind into the open.RKLB: Critical Moving Averages and Levels to WatchThe bigger-picture trend is still constructive: RKLB is trading 49.6% above its 200-day SMA ($72.00) and 24.7% above its 100-day SMA ($86.36), with the 50-day SMA above the 200-day SMA reinforcing the longer-term uptrend.Near-term, the chart is in a cooldown/reset phase after May's peak—price is trading 15.1% below the 20-day SMA ($126.89) but still 8.8% above the 50-day SMA ($98.99), a common setup where bulls want to see the 50-day area act as a "line in the sand."MACD is the cleaner momentum lens right now: with MACD below its signal line and the histogram negative, it suggests upside pressure is cooling versus the prior upswing unless buyers can reclaim that baseline. That lines up with the idea that the stock is consolidating after a parabolic move rather than immediately resuming the straight-up trend.
