SpaceX IPO Lifts Space Stocks- Is Rocket Lab the Biggest Winner?

KEY POINTS

  • SpaceX just had the biggest IPO ever, and it has pulled attention back to space stocks.
  • Rocket Lab (NASDAQ: RKLB) is the clearest space company most investors can actually buy, and it joins the Nasdaq-100 on 22 June.
  • It is a real business with growing sales and a big defence contract, not just hype.
  • The catch: the stock has more than tripled in a year and now looks expensive.

Is Rocket Lab (NASDAQ: RKLB) the biggest winner from the SpaceX excitement? Out of the stocks you can actually buy, it is the clearest one. But after a huge run, a lot of the good news is already in the price.

SpaceX just pulled off the largest stock market debut in history. It priced its shares at a fixed US$135, valuing the company at about US$1.75 trillion, and with only a small slice of stock on offer and demand running hot, the price jumped about 19% on day one to close at more than US$2 trillion. With SpaceX itself hard to get into, investors are hunting for the next best thing, and Rocket Lab is the name most of them land on.

A Well-Timed Move Into the Nasdaq-100

Rocket Lab will join the Nasdaq-100 on 22 June, putting it in the same index as Nvidia and Apple. That matters because the funds that track the index have to buy any stock that joins, no matter the price. So, Rocket Lab gets a fresh wave of buyers it did not have to earn with results.

It helps, but it is a one-off boost, not proof that the business suddenly got better. In fact, the shares fell 10.8% on Friday to close at US$102.39 as investors locked in profits, even while SpaceX dominated the headlines. That tells you how much excitement is already baked in.

A Real Business, Not Just Hype

Look past the buzz, and there is a genuine company here. Rocket Lab’s Electron is one of the world’s most-launched small rockets, and it is now building a larger rocket called Neutron that could one day compete for the kind of work SpaceX dominates.

The money side is catching up, too. Sales grew 38% last year, and the company recently won its biggest contract ever, an US$816 million US defence deal to build missile-tracking satellites. That mix of defence and commercial work makes it far more than a stock story. The main risk is simple: Neutron needs to fly on time, or the bigger growth story stalls.

The Investor’s Takeaway for RKLB

Here is the honest view. The SpaceX buzz and the index entry are great for mood, but neither one changes what Rocket Lab earns next year. The stock has more than tripled over the past year and now looks expensive against the sales it actually makes. At least one analysis already calls it overvalued.

For growth investors who can handle big swings, Rocket Lab is probably the best listed way to back the space theme. For everyone else, chasing it after such a sharp run is the real danger, as Friday’s drop showed. So is it the biggest winner? On momentum, yes. On price, much of that win is already gone.
