Investors have been riveted by the ups and downs of Space Exploration Technologies Corporation, or SpaceX (NASDAQ) stock. After its IPO on 12 June, the share price rocketed to $225, then crashed to $104. Today, it’s around $137. Quite a ride.

FTSE 100 engineering giant Rolls-Royce (LSE: RR) has mostly been going up. It’s rocketed 1,087% over the last five years. So where will these two stock market heroes go next? That’s anybody’s guess, but let’s see what the experts say.

Can Elon Musk reach for the stars?

SpaceX forecasts are suitably wild. Investment firm Raymond James reckons Elon Musk’s interstellar stock could hit $800 in the next 12 months, driven by its Starship launch technology and orbital computing infrastructure. That’s an increase of 484%, turning £10,000 into a staggering £58,394.

If you think that’s too bullish, you’re not alone. Consensus forecast is $226, up 65% from today. Still pretty tempting.

Today, the Rolls-Royce share price trades at 1,519p. Broker Morgan Stanley reckons it could hit 2,000p in 12 months. If correct, that’s an increase of 31.7%. Consensus target is 1,757p, up around 15%. I hold the stock and would be content with that.

Interestingly, lowball forecasts tell us a lot. One broker reckons SpaceX stock will crash 45% to just $75. The lowest forecast for Rolls-Royce suggests is 1,500p, a modest 1.25% dip.

Can these shares avoid meltdowns? 

I hold Rolls-Royce directly, and SpaceX indirectly, via the Scottish Mortgage Investment Trust. Personally, I think Rolls is a Hold and SpaceX a high-risk Buy. But what does artificial intelligence (AI) think? I showed ChatGPT what I’d written so far and asked if either stock might crash 50% in the next year.

ChatGPT aims to please. It’s first response echoed what I’ve just said: “I’d make the point that 50% falls are conceivable for both, but vastly more plausible for SpaceX than Rolls-Royce”.

It noted that SpaceX has already shown how violently its shares can move, saying: “SpaceX has extraordinary growth prospects, and its valuation reflects enormous expectations around Starlink, launch services, artificial intelligence and its longer-term ambitions”.

Noting that’s also the danger, it added: “When expectations are sky-high, even a disappointing launch, slower growth or a wobble in the AI story could trigger a brutal repricing”.

Which one’s riskier?

ChatGPT emphasised that Rolls-Royce “is an established FTSE 100 business with substantial recurring revenues from servicing aircraft engines”.

It added: “A 50% fall is certainly possible, if investors decide the shares have become wildly overvalued or the global economy deteriorates sharply. But I’d regard it as considerably less likely”.

Rather like those brokers then. ChatGPT continued: “SpaceX is the one I would lose sleep over.” Odd, I didn’t think chatbots slept. It concluded: “Could either stock halve? Absolutely. Would I bet on it happening within a year? No”.

Here’s my view. Both are fabulous enterprises and well worth considering. But Rolls is expensive with a price-to-earnings ratio of more than 50. Maybe one to look at on a dip. The SpaceX share price could go anywhere, but might just be massive. Worth considering, for investors willing to take the gamble.
