April 4 (Reuters) - Nvidia Corp ( NVDA ) and Alphabet

Inc ( GOOG ) saw the biggest jump in their market

capitalisation in March, driven by artificial intelligence (AI)

enthusiasm and anticipation for new products and expansion

plans.

Nvidia's ( NVDA ) market cap soared to $2.25 trillion at March-end,

up 14% from February, while Alphabet's rose 9% to $1.8 trillion.

Nvidia's ( NVDA ) shares saw an upswing last month as the company

announced its latest flagship AI processor is slated for release

later this year, while Alphabet's shares got a lift from reports

of Apple's ( AAPL ) interest in integrating Google's Gemini AI

engine into the iPhone.

The AI-driven market optimism also lifted Taiwan

Semiconductor Manufacturing Company ( TSM ) . TSMC's

market cap jumped about 12% to $632.5 billion.

Conversely, Tesla Inc ( TSLA ) faced the largest market cap

drop, falling about 13% to $559.8 billion amid demand concerns,

rising competition, and scrutiny over CEO Elon Musk's $56

billion pay package.

Apple Inc ( AAPL ) experienced a decline, with its market cap

dropping 5.1% to $2.65 trillion, amid slowing iPhone sales and a

recent $2 billion fine from European regulators for antitrust

violations.

Overall, major tech firms have experienced significant

market gains this year. So far in 2024, Nvidia ( NVDA ), Meta Platforms ( META )

, and TSMC's market caps have risen 81.8%, 42%, and

26%, respectively.

"For investors with excessive exposure to large-cap tech

names and looking to diversify beyond the sector, we see

opportunities in US small-caps and select European small- and

mid-cap stocks," said Mark Haefele, chief investment officer at

UBS Global Wealth Management.

"We think their performance should approach that of their

large-cap peers amid a supportive macro backdrop, and we see

value in adding them in portfolios."
