Has Broadcom Become Too Expensive for Its AI Story?

Few companies have ridden the artificial intelligence (AI) infrastructure boom as successfully as Broadcom NASDAQ: AVGO.

The tech giant has been a go-to name for investors looking to play the buildout of AI data centers, and its shares are up around 40% over the past year as a result.

Every fresh sign of accelerating demand for its custom chips has been met with enthusiasm, and for good reason.

Lately, though, that enthusiasm has started to cool in a way that's worth paying attention to.

Despite briefly hitting an all-time high after its earnings report last month, the stock has since fallen more than 20% from that peak.

More tellingly, it's now trading at roughly the same level it was back in November, meaning it has effectively gone nowhere in eight months, even as the company has continued to post exceptionally strong results.

For a stock that's supposed to be one of the AI trade's biggest winners, that's not a great look, and it's forcing investors to confront an uncomfortable question.

The Downgrade That Put Valuation Front and Center The clearest sign of the growing unease came last week, when Erste Group downgraded Broadcom to Hold from Buy, citing valuation concerns.

The move stands out against a broader Wall Street backdrop that remains bullish overall, with Broadcom carrying a Moderate Buy consensus rating.

The reasoning was blunt: while the firm acknowledged that the company’s margins are expected to remain high, the stock's already lofty valuation reflects much of that positive outlook, leaving limited room for further price appreciation.

That's a critical point, and it goes straight to the heart of the bear case.

Broadcom's fundamentals aren't in question.

The concern is entirely about how much investors are being asked to pay for them.

Right now, the stock is costing around 65 times earnings, considerably higher than, say, the 32 times earnings investors are being asked to pay for NVIDIA NASDAQ: NVDA.

When a stock is priced for perfection, even excellent results can fail to move the needle, because the good news is already baked in.

The fact that Broadcom has essentially flatlined since November despite continued strong performance is arguably the market's way of signaling exactly that.

Morgan Stanley, for example, described the company as a "core AI winner,” pointing to the strength of its AI growth trajectory despite recent concerns about valuation and competition.

The team there put much of the weakness down to two things.

First, investors have been gravitating toward what they call "growthier" bottleneck stories elsewhere in the AI semiconductor space, leaving Broadcom looking comparatively unloved.

Second, and more specifically, there's been growing c...
