Oct 29 (Reuters) - Shares in three of the "Magnificent

Seven" companies with significant investments in artificial

intelligence were mixed in after-hours trade on Wednesday after

the mega caps released third quarter earnings.

Shares in Google-parent Alphabet rose 6.2% after

the company beat Wall Street estimates for third-quarter revenue

on Wednesday, as both its core advertising business and cloud

computing unit showed steady growth.

The cloud services and AI giant raised its capital

expenditure forecast for the year to between $91 billion and $93

billion, compared with the estimates of $80.67 billion.

But Microsoft ( MSFT ) fell 3.4% in extended trading even

though the company reported blockbuster growth in its

cloud-computing business that pushed its quarterly revenue past

Wall Street estimates, showing businesses are still splurging on

AI services despite fears of a bubble.

The results highlight the growing returns from Microsoft's ( MSFT )

massive AI investments.

Shares in Meta fell more than 8% after it said it

recorded a nearly $16 billion one-time charge in the third

quarter related to U.S. President Donald Trump's Big Beautiful

Bill, and said its capital expenditure next year would be

"notably larger" than in 2025.

Meta has been doubling down on AI, CEO Mark Zuckerberg has

personally led an aggressive talent hiring spree and has said

that the company would spend hundreds of billions of dollars to

build several massive AI data centers for superintelligence.

COMMENTS:

STEVE SOSNICK, CHIEF STRATEGIST, INTERACTIVE BROKERS,

"From a broad market point of view, they're sort of a push

(not an index catalyst) because the good reaction in Alphabet is

enough to offset the uninspiring outcome in Microsoft ( MSFT ) and the

surprise tax loss at Meta. The reactions in Meta and Alphabet

are currently greater than the implied volatility moves that

were priced into weekly options, but not egregiously so, with

Microsoft ( MSFT ) being a somewhat more subdued move."

BESPOKE INVESTMENT GROUP (emailed note)

"Taken together, while these results weren't all necessarily

constructive for the stocks they show zero signal of a slowdown

in the AI capex boom. Their combined capex rose $14bn QoQ or

more than 22%, (the same pace as last quarter) and is up 88%

YoY."
