Question of RKLB Stock Valuation

I have a serious question/concern and not trying to hate on Rocket Lab. I am holding significant amount of shares of RKLB so I have a vested interest in wanting the company to do well.

For the past month or so been doing some more research and just looking at the overall fundamentals and numbers. I did that before when RKLB stock price was well below its current value and saw value. With the meteoric rise of the price I wanted to see if its now overvalued and by how much. Every ratio I look at compared to their industry peers points to an overvaluation. Just looking at basic ratios of P/E, which is negative, not profitable, but we know that and have to look at other metrics. Negative P/E throws PEG out the window.

Looking at P/S they are at around 38-40. That's a high number compared to other companies in aerospace or defense industry which is around a P/S of 2-4. Their P/B is around 33 which is also high compared to industry peers. But this high ratio can also be looked at as investor optimism for growth. Their industry is between 2 - 5, No matter what ratio, metric or fundamental you look at, it all points to an overvaluation of the stock. I understand they have a backlog of about $1billion which about half or more will be converted to revenue within a year. That being said is it safe to assume that near term future growth is already priced in? Or will we see a correction in price back down to mid teens.

Serious thought, question, discussion.

Counter input and critical criticism appreciated.
