Goldman Sachs on bubble speculation: “We don’t think we are in one yet”

But they still think investors should focus on diversifying.

The great debate continues over whether we’re watching a major asset bubble inflate, with Goldman Sachs analysts weighing in with a beefy analysis focusing heavily on the valuation of giant tech stocks like Nvidia, Microsoft, Amazon, and Tesla this morning.

Here’s their upshot:

“There is still a risk that we end in a bubble but, on balance, we don’t think we are in one yet.

Also, if investors started to lose faith or patience in the AI theme, there is a smaller risk of an economy-wide effect that in many previous bubble episodes because private sector balance sheets remain relatively healthy. There is less leverage or debt that is financing the current spending boom and, importantly, banks’ balance sheets are strong.

None of this would prevent a market correction in the event of a de-rating of technology and AI growth prospects, however. Given these risks, we continue to focus on diversification strategies.”

Goldman has some very smart analysts. But as with all sell-side research, it should be read with a few grains of salt.

Sell-side analysts who predict bubbles don’t tend to remain sell-side analysts for long. That’s because their “side” is “selling” securities, which people don’t buy if they’re worried a bubble could pop and crush the market.

Still, Goldman did a lot of work on valuations in its analysis, finding that “it is underlying profitability and return on equity that has largely explained the rise in valuations.”

In other words, the high valuation of the US market — and the S&P 500’s price-to-earnings multiple is a remarkable 23x forward earnings — is largely justified by the fact that the US tech sector generates such massive profits.

IREN drops on convertible debt offering

Shares of crypto miner and AI compute provider IREN dropped after the Australia-based, US-listed company said late Tuesday that it would sell $875 million in convertible senior debt.

The announcement came late in the trading day and caused a sell-off in the aftermarket session that continued into Wednesday trading.

The offering makes sense; the company can probably get some fairly cheap capital after its shares doubled over the last month.

But it exposes shareholders to some dilution risk if buyers of the hybrid securities do convert them into equity, which explains the market reaction.

AST SpaceMobile moons on Verizon deal

Satellite operator AST SpaceMobile rocketed in early trading after announcing a deal with Verizon in which the telecom giant will use AST’s satellites to provide cellular broadband service “when needed for Verizon customers starting in 2026.”

The market seems to view the announcement as a vote of confidence for the recent romp of services-from-space stocks. Planet Labs and Rocket Lab, which also announced a deal for three new launches on Tuesday afternoon, were both up sharply in early trading.
