U.S. stocks finished mixed Monday as investors embraced Apple's latest AI initiatives unveiled at its Worldwide Developers Conference while weighing a fresh increase in oil prices tied to renewed hostility between Iran and Israel.

The Dow Jones Industrial Average fell 80.77 points, or 0.16%, to 50,786.0. The S&P 500 gained 21.94 points, or 0.30%, to 7,405.68, while the Nasdaq Composite climbed 220.23 points, or 0.86%, to 25,929.7.

Technology shares led the advance after Apple outlined what many investors viewed as its most significant AI strategy update to date. According to a new Wedbush research note, analysts described the event as "the start of Apple's foundational AI consumer platform shift" and argued that the unveiling of Siri AI could transform how Apple's roughly 2.5 billion-device installed base interacts with its ecosystem.

Wedbush maintained its Outperform rating and $400 price target, stating that AI monetization could ultimately add "$75 to $100" per share to Apple's valuation.

Market sentiment was also helped by a sharp decline in volatility. The CBOE Volatility Index, or VIX, fell 11.93% to 18.95, suggesting investors were becoming more comfortable taking risk despite geopolitical uncertainties.

Those uncertainties remained visible in commodity markets. Brent crude rose $1.34, or 1.44%, to $94.43 a barrel after reports of continued exchanges between Iran and Israel fueled concerns about potential disruptions to energy supplies. According to Yahoo Finance, oil prices moved higher as traders monitored developments in the Middle East and assessed risks to regional production and shipping routes.

Investors are also preparing for what could be one of the most closely watched public offerings in history. SpaceX's IPO is expected to debut this week, with investors scrutinizing the company's limited public float and unprecedented valuation. While enthusiasm surrounding the offering remains high, market participants continue to debate how much influence the stock could ultimately have on major indexes given the relatively small percentage of shares expected to trade publicly.

Looking ahead, investors will continue to monitor the Iran War and look ahead to Oracle reporting its quarterly earnings scheduled to be released after the bell on Wednesday.
