Rocket Lab soars on analyst coverage, contract news, and launches

On June 10, Cantor Fitzgerald published new coverage on Rocket Lab. Andres Sheppard, the firm's lead analyst on the stock, reiterated an overweight rating and raised his one-year price target from $29 per share to $35 per share. Sheppard pointed to Rocket Lab's successful launch history, different rocket types, and launch sites as strong competitive advantages. He also noted that Rocket Lab could benefit from the worsening relationship between President Trump and SpaceX CEO Elon Musk.

Late in the month, Rocket Lab announced that it had landed a contract with the European Space Agency (ESA) to launch two satellites. The news prompted a substantial rally for the stock, and shares moved even higher after the company announced the launches of its 67th and 68th Electron rockets. The two launches occurred at the same launch site within 48 hours, marking the company's fastest-ever turnaround time for a launch. The news pushed Rocket Lab stock to a new record high, and it's kept climbing from there.

Why has Rocket Lab stock kept surging in July?

Rocket Lab stock has continued on its upward trajectory this month. As of this writing, the company's share price is up 8.2% across July's trading. In addition to continued excitement surrounding its opportunities in the space industry, the stock has gotten a lift from bullish analyst coverage.

In a note published July 2, KeyBanc maintained an overweight rating on Rocket Lab and raised its price target on the stock from $29 per share to $40 per share. As of this writing, KeyBanc's latest price target implies additional upside of roughly 3%.

Rocket Lab now has a valuation of roughly $17.9 billion and is trading at approximately 31 times this year's expected sales. While the recent rally for the stock may raise questions about whether the company's valuation has become unreasonably stretched, the business looks poised to grow at a rapid clip in the near term and seemingly has huge expansion opportunities over the long haul.
