S&P 500 ends marginally lower as investors focus on US-Iran war

Wow, what a rollercoaster today as Houthi attacks on Saudi Arabia once again pushed up the price of oil to $107/barrel, also continuing to push up the 30-year yield which today reached a 22-year high. All three indexes were way down in the morning, the Dow plunging nearly 400 by noon with the other indexes following suit. Then right around the noon hour, everything shot right back up again almost instantly as Reuters reported that a deal was in the works for a gradual reopening of the Strait of Hormuz and for phasing out Trump’s blockades of Iran.

Iran’s president fired back at Trump hard at the UN vowing “never surrender” and immediately sent price of oil soaring again, the 10-year Treasury going above 5% again, the highest since 2007 (and now flirting with the dreaded 6%), Nvidia dropping 1.5% and the chip index itself 1.2%. Clearly, the market wants an end to this war. Clearly, the market isn’t going to get it.

The AI relief train continued running today as demand “showed no signs of abating and corporate earnings stayed resilient.” This combined with oil flows from Saudi Arabia increasing and the 10-year yields decreasing sent the Nasdaq to another triple-digit gain and another record. There was also hope when Iran said it could open the Strait of Hormuz in as little as a week but this was conditional on Trump backing off and who knows if that will happen.

After last week’s drubbing, the markets went into high gear today with the price of crude dropping below the psychologically important $100/barrel mark and yields dropping below the psychologically important 5% mark. The Nasdaq marked its first record since its all-time high June 2^nd and the S&P closed within a whisper of its August 13^th record. New data suggesting that AI spending is expanding despite recent warnings sent tech way up.

It was certainly a very volatile day as all three indexes dipped well into the red in the morning, the Dow down almost 300 by 12:30, then all three began a rebound with the Dow recapturing most but not all of its losses by close, but tech actually making it a bit into the black. The Nasdaq especially gained over 100 as investors continue to digest inflation data and the first Fed rate hike in years while trying to determine the next steps. What likely helped tech was the Chinese serving as an intermediary with Iran to try to stop the attacks on Saudi Arabia and its oil routes.

Yesterday’s news of the Saudis sending oil through Oman helped ease fears of a deepening fuel shortage which brought crude down and subsequent Treasury yields. And because of the slaughter the markets have recently endured, there was some bargain hunting going on too, all which combined for massive 3-digit gains all around which began right out the gate and stayed there steadily all day. As one might also guess, the recent panic in equities has translated to gold and silver mining stocks being the outperformers, advancing more than 3%.

Robust retail sales provided a bit of a lift to all the indexes this morning and that combined with Saudi Arabia allowing tankers through via Oman kept everything steady. It had the desired effect on the price of crude which dropped 3% and also brought the chip index up 0.6%.  Then at 2 pm, everything dropped like a rock as it was likely at 2 pm that the Fed announced the first rate hike in more than three years along with the announcement that this would be only one of several more coming.
