Stocks Recovered, Money Stayed Expensive

The S&P 500 set a record on Tuesday, stumbled as an AI revenue headline hit technology stocks, and rose 0.6% on Friday. The Dow rose 0.8% Friday and the Nasdaq Composite added 0.6%. The chart below puts the week’s equity gains alongside the change in Treasury yields.

October2 to October9,2026: S&P500 +1.15%, Dow +0.93%, Nasdaq Composite +0.64%; ten-year Treasury par yield fell from5.28% to5.24%.

The Treasury’s official ten-year par yield ended Friday at 5.24%, down four basis points from a week earlier. Capital remains expensive, even as stocks recover.

The AI Headline Needed A Reconciliation

Thursday’s selloff followed reports putting OpenAI’s annualized revenue near $50 billion, versus an earlier $68 billion figure that included gross partner revenue. Subsequent reporting explained the different treatment of those sales. Our AI accounting analysis separates that presentation issue from the financing hurdle facing the buildout.

That distinction matters for stock selection. Suppliers’ orders, delivery schedules and customers’ ability to pay tell us more about their earnings prospects than two differently constructed revenue headlines. Our new ideas this week also reached beyond infrastructure, into businesses putting AI to work and companies with their own adoption or turnaround catalysts.

How We Traded It

Monday: Our first alert focused on turning AI capabilities into recurring software revenue. The proposed call diagonal didn’t fill; we returned to that setup on Wednesday.

The Week’s Final Two Sessions

Thursday: Our four opportunities covered specialty-food distribution, a Bitcoin rebound, a bearish profitability trend and a chipmaking earnings catalyst. The Bitcoin call diagonal filled; the other three orders were canceled.

Friday: A turnaround and a return paired business communications with AI tools and improving finances with a biotech we’ve profitably traded before. We opened the communications trade; the biotech order remained unfilled.

Closing The Robotics Trade

Ouster makes lidar sensors that help robots and autonomous machines see their surroundings. We exited the remaining put spread in our May trade on October 5th, completing an exit that began with the sale of its call diagonal in August.

Here’s the original entry card from our May 21st alert. The trade is now closed.

Historical Ouster entry from May21,2026: original $1.85 limit, four-leg hybrid combo, maximum risk $685 at the published limit.

We entered at a $1.45 net debit, below the card’s $1.85 limit. The completed trade earned $857, or 132.9% on its $645 original maximum risk, before fees. The exit card shows both stages.

Ouster historical full-exit card 12: entered at $1.45 on May 21, 2026; call diagonal exited at $10.22 on August 17; remaining put spread exited at $0.20 on October 5; 132.9% return on original maximum risk, 591.0% on net debit, before fees.

Our next entries will continue to combine business evidence with quantitative screens and the available options prices. This week’s ideas ranged from AI software and medical innovation to a turnaround and a bearish profitability trend; we’ll keep looking wherever a compelling setup emerges.
