More threats against Iran plus now additional threats against allies trading with Iran continued to aggravate war worries and send tech down, the chips hit particularly hard. All of this was further exacerbated by the continuing and very omnipresent opposition to the building of AI centers with even Texas governor Abbott now joining the protests. All the turbulence has continued to push the 30-year bond higher with Bessent considering tapping into the $1T General Account to continue bond buybacks.

Investors took a bit of a breather today and there was some old-fashioned bargain hunting as all the indexes went steadily straight up despite bond yields continuing to rise and the war with no end in sight. Trump has threatened severe economic sanctions against Iran and Iran has countered by vowing a “devastating” response if it happens. None of this seemed to sour investors and the light volume suggested “wait-and-see” and there’s a lot to wait-and see.

Just as two good things happened yesterday, two bad things happened today. First and foremost, those long-awaited retail numbers to show the health of the market came in very weak, with bellwether Walmart very much disappointing which crashed its stock down 9.2%. As could be expected, other retail giants followed suit with losses between 1 and 2.6%.

This morning two big things happened. First, the Treasury offered substantial buy back support on the 30-year and 10-year bonds which went through the roof yesterday sending the yields to multi-decade highs. This shot inflation prospects through the roof so the offer served to bring the yields back down, which it did. This had a healthy effect on tech, pushing companies like Marvell up 9.9% though the overall chip index fell 2%.

As markets go, bonds tend to run inversely to equities given the simple fact that equities are where you go for growth when there is good news and bonds are a place of retreat from bad news. Today the bond markets climbed suggesting that the equity markets may be in trouble and that caused a flight from all three indexes to the 30-year Treasuries. And with the war showing no progress towards peace, that shot the oil market up which further increased bond yields which further raised the cost of borrowing.

Though it’s unclear exactly what happened at the noon hour, it was at that time that all three indexes dove into the red with all three closing with greater losses than Friday. The Dow took the brunt of it as the price of oil rising, with Iran still at a standstill. Some of it is just fence-sitting as investors still digest the weak retail sales and job numbers from July and anxiously awaiting new retail sales in the next few days from giants Walmart and Home Depot.

Weaker retail sales data combined with a drop in confidence once again in AI brought all three indexes down after yesterday’s tech rally and another S&P record. The kicker was Applied Materials which, though it turned in a glowing Q3 forecast, was not enough to satisfy the high expectations and thus the share price fell and that again impacted overall AI sentiment as being overwrought, dropping other AI chip stocks.

PPI was out today and like the CPI showed a flat increase in prices once again bolstering hopes that there will be no rate increase next month and subsequently sending a number of more chip companies surging, the Nasdaq once again up a respectable 3-digits and the S&P with its 50-point gain reaching another new record. After a 300-point morning surge, the Dow dropped to a minus 150 by noon, then back up and remained relatively flat the rest of the day.

Several AI companies turning in good reports shot the tech indexes straight up to decent gains with both the Nasdaq and S&P regaining almost all of yesterday’s losses. The enthusiasm also spilled over to the companies building data centers with stocks like Nebus boosting an amazing 34%. Combine that with the good news that CPI came in basically flat.

For the second day after new proposals to end the war have utterly failed, the market took a dive straight down, this time much more seriously than yesterday. As Iran said, “The Strait of Hormuz will remain closed until the U.S. accepts Iran’s conditions to end the war.” As of this past weekend, those conditions now include the U.S. paying restitution for all the damage done to Iran. As reported yesterday, Trump has countered that by demanding Iran pay restitution for every American lost in the attacks by Iran.

The peace negotiations have become a sticky wicket with Tehran now demanding compensation for all the damage done by U.S. strikes during this war and Trump countering by demanding compensation for all lives lost in the war. Suddenly a deal to reopen the Strait of Hormuz appears at a standstill and with hopes fading for this critical aspect of the negotiations which could bring down the price of oil and help stabilize inflation, the markets turned downward. The Nasdaq closed down the hardest, the S&P stayed pretty close to flat after Friday’s record.

Per today’s jobs report, the economy lost over 100,000 jobs, that is if you’re counting the 80,000 forecasted increase that didn’t happen and the 23,000 unexpected decrease that did. It was good news on the inflation front as providing more fodder to stall off a rate increase. The odds today of a September increase has fallen to 44% vs yesterday’s 55 vs last week’s 67. That’s a 35% decrease in a week.

Peace hopes got muted today over the impending opening of the Strait of Hormuz but with the Iranian parliament considering banning the U.S. and its allies from using it. This combined with more AI jitters brought all three indexes down for a second day after a very vigorous 3-day rally. Oddly, two of the tech companies that fell today, Western Digital and Sandisk, actually turned in glowing Q2 and have been booming this year, Western up 400%, Sandisk 160%.

After four straight days of big gains, a couple of disappointing Q2 AI reports, namely from SpaceX and AMD, brought both tech indexes down but progress in the peace talks concerning a deal between Oman and Iran brought oil down and shot the Dow up to yet another record. SpaceX and AMD actually had reasonably good reports with SpaceX actually doubling revenues. But their expenses were still more than their revenues raising the old doubts that these massive AI investments will pay off.

Optimism over earnings and an end to the war shot all the indexes straight up again for the fourth straight day, today even more impressively than before with high 3-digit gains all around. The Dow reached a new record for the second straight day, the S&P its first new record since July 2^nd. Caterpillar provided the biggest boost to the Dow with increasing demand for its equipment in building AI centers. Palantir got an astonishing 29.5% boost and the chip index rose 6.6%. Crude dropped 5% on Qatari confirmations that peace talks were continuing.

Optimism is back up front with all three indexes jumping straight up out the gate and staying up all day, all achieving very substantial 3-digit gains again, the Dow not only now handsomely recouping all its losses but reaching another record high. The good news is new hopes over Iran as fighting de-escalates and bringing crude prices down 5%.  With 304 of 500 S&P companies now reporting and 85.2% beating estimates, Q2 earnings growth now stands at 29.3%, but oddly down from Friday’s 48%.
