The NASDAQ's remarkable recent performance, with technology companies leading an aggressive bull run, has drawn attention to the buzz surrounding artificial intelligence (AI). Citadel CEO Ken Griffin suggests caution, warning against overhyping expectations for generative AI at this nascent stage of tech sector growth. During a recent event Griffin stressed that over-expectations could potentially backfire and harm the sector.

The billionaire investor has acknowledged the transformative potential of advanced technologies. However, he has emphasized that these technologies are still early in their development. He has also dismissed the idea that AI is set to obliterate skilled professional jobs as unrealistic.

As previously noted, the intense media focus on AI has fueled the NASDAQ's bull run, particularly as demand for tech stocks soared in the aftermath of a financial shakeup that saw several American lenders collapse in March.

Market indicators have underscored this shift, with tech giant Nvidia's market capitalization topping $1 trillion. The AI-based chat-bot, ChatGPT, capable of delivering human-like responses to user queries, has made significant waves in the sector, quickly becoming a global phenomenon and one of the fastest-growing software platforms in history.

Pre-market movers

Shares of Tesla saw a 3% pre-market bump following a company website update revealing that the new Model 3 and Model Y vehicles will be eligible for a $7,500 US tax break under the Inflation Reduction Act.

Streaming behemoth Netflix has seen a 3.1% climb during the pre-market after JPMorgan revised its stock price target upward. JPMorgan cited the company's proactive steps to curb password sharing on its platform, a move it says could lead to significant revenue growth.

In the gaming sector, GameStop's shares added 2.4% in pre-market trading as investors await the company's quarterly results, due today. Market analysts anticipate adjusted quarterly losses of 15 cents per share.

Meanwhile, shares of Brazil's oil powerhouse Petrobas jumped by 2% in pre-market trading. The rise follows Morgan Stanley's decision to upgrade its rating of the company's stock to 'buy' from 'hold'. Morgan Stanley predicts Petrobas could offer investors larger dividends this year compared to 2022.

Regarding the technical situation of the S&P 500, demand for the index has somewhat returned. Bulls still have a chance to start an upward trend, but they need to cling on to $4,290, from where a jump to $4320 can occur. An equally important task for the bulls will be to maintain control over $4,370, which will strengthen the bull market. In case of a downward movement against the backdrop of reduced risk appetite and hawkish comments from Fed representatives, buyers will have to act around $4,255 and $4,230. A breakout below these levels will quickly push the trading instrument back to $4,175 and open the path to $4,143.
