Stock Market Summary – June 23, 2025

After a volatile session filled with geopolitical headlines due to tensions in the Middle East following U.S. bombings of Iranian nuclear sites, the S&P 500 was up around 0.7%. Despite concerns of a market sell-off after the bombings, stocks traded higher, and the market ultimately viewed Iran’s response as not as bad as feared. Tensions temporarily rose around noon ET due to initial reports of Iran attacking a U.S. military base in Qatar, causing the market to reverse its initial upward trend. But after it was reported that the missiles were intercepted and there were no casualties, oil prices dropped, which usually indicates de-escalation, and stocks rallied.

In company news, Cisco Systems, known for its strides in AI and cybersecurity, has been added to the CNBC Investing Club’s Bullpen watchlist. The company recently reported strong quarterly results and issued better-than-expected guidance. The stock has been performing well, with a 13% rally in 2025 and higher margin revenues from its ongoing transition toward subscription software.

Super Micro Computer on the other hand, saw its shares fall 10% following an announcement that it plans to offer $2 billion in convertible notes maturing in 2030. The company has seen a surge in business due to demand for Nvidia’s AI processors, the convertible notes could dilute the stakes of existing shareholders, causing the investment downturn.

Despite U.S. involvements in the Middle East, U.S. oil benchmark West Texas Intermediate and Brent fell by over 5%, and U.S. stocks eventually opened higher. CNBC’s Jim Cramer attributes this to the changing global energy market and the rise in U.S. oil production.

Additionally, President Trump said on a social media post that “everyone” should keep oil prices low to not “play into the hands of the enemy”. Cramer noted that many individual companies lifted their stocks due to positive news. In conclusion, geopolitical issues may impact oil prices and subsequently stock markets, but company performance and the changing global energy market may also play a key role.

Amid escalating conflict in the Middle East, ocean freight rates to the Port of Khor Fakkan in the UAE have surged 76% since mid-May due to increased risk and operational costs, according to data by Xeneta. The increase is attributed to tensions following Israeli and U.S. attacks on Iranian targets.

Despite the geopolitical tension, the market has remained resilient, stated investor Tom Lee. No significant changes have been observed in the major averages or oil prices, and Lee predicts stocks should perform well towards the end of the year.

Notably, Tesla shares jumped over 10% following the successful rollout of its robotaxi service in Austin, Texas, while Northern Trust saw a 7% rise after reports of potential merger interest from Bank of New York Mellon. Fiserv rose almost 3% as the financial services firm unveiled plans to expand into the stablecoin space, announcing a new blockchain-based digital asset platform, a move that also saw Circle’s shares increase by 18%.

However, not all companies enjoyed positive movements. Novo Nordisk fell over 5% following disappointing results for its obesity drug, CagriSema, and the termination of its collaboration with Hims & Hers Health, whose shares fell over 30%. Super Micro Computer saw a 7% drop after it announced a proposed offering of $2 billion in convertible senior notes.

In the wake of the U.S.’s strikes against Iran, petroleum stocks shifted as President Donald Trump called for lower oil prices, causing slow slips in shares for ConocoPhillips and Marathon Petroleum. Defense stocks were also mixed, while shares correlated with nuclear energy, like Constellation Energy, saw an uptake as New York State Governor Kathy Hochul considers developing a new nuclear power plant.

Lastly, Fiserv’s entry into the stablecoin market with a U.S. dollar-pegged stablecoin and their subsequent relationship with Circle could bring thousands of banks and millions of merchants into the crypto economy. On the back of this news, Circle’s share value rose by 6% to $250.

Following the latest U.S. airstrikes on Iran’s nuclear development facilities, Iran retaliated by launching missiles at a U.S. military base in Qatar. Despite this, crude oil prices fell after the attacks, suggesting markets are not overly concerned about interrupted supply.
