From the screens of Chauhan

June 23 (Reuters) - Shares of U.S. chipmakers suffered losses on Tuesday, but an earlier market pullback attracted investors seeking attractive investment opportunities, limiting losses for other companies that have contributed significantly to supporting the artificial intelligence infrastructure that has boosted the market over the past few years.

The Nasdaq Composite Index fell 1.4 percent, wiping out approximately $680 billion in market capitalization for its listed companies during morning trading. SpaceX, owned by Elon Musk, briefly dipped below $2 trillion for the first time since its IPO this month before recovering.

The technology sector experienced its first sharp sell-off in weeks in recent days, with the Nasdaq index falling nearly 5% from its closing high in early June. Nvidia, the world's most valuable company, saw its market capitalization drop 2.6% to below $5 trillion. The decline in shares of Nvidia and Tesla was among the biggest factors weighing on the Nasdaq.

Chipmakers, which had been among the biggest winners in the artificial intelligence sector this year, suffered heavy losses, with the Philadelphia Semiconductor Index falling 6.3 percent. Shares of Micron, one of the most profitable companies in recent months, also dropped 9 percent. The company will announce its earnings after the markets close on Wednesday.

Shares of memory chip makers, the best performers on the S&P 500 this year, also declined today, with SanDisk and Western Digital shares falling 12% and 11%, respectively. Shares of memory chip makers in South Korea also plummeted.

In contrast, SpaceX shares rose 1.7 percent to $157 after 10:40 a.m. Eastern Time (1440 GMT), after having fallen to $147.11, marking their first dip below the opening price of $150.

Other major technology companies fared differently. Alphabet shares fell 0.4 percent, while Apple shares rose 0.8 percent and Microsoft shares climbed more than 2 percent. Shares of software companies such as WorkDay and Salesforce also rebounded after sharp declines this year amid concerns about artificial intelligence.

Lauren Hislop, investment director at Mattioli Woods, noted that among the reasons for the heavy selling was dealing with economic conditions characterized by high or rapidly fluctuating borrowing costs, as well as concerns about the amount of capital required to fund the next phase of investment in artificial intelligence.

SpaceX's record-breaking initial public offering led to a surge in trading during the company's first week of listing, but the stock has plummeted in recent trading sessions, causing the company's market value to drop by more than $600 billion since last Wednesday.

Nick Pokren, a multi-asset analyst and founder of CoinEuro, said, "I would advise caution in viewing this as another buying opportunity. The drop looks sharp, but such volatility is not unusual for a stock with such a low trading volume."

The company's stock is currently trading at a premium of more than 10 percent over its initial offering price of $135.

SpaceX announced Tuesday that it is turning to the bond market for the first time, just days after the company's initial public offering.
