After the close Amazon showed the same pattern: AWS growth accelerated, but the build turned twelve-month free cash flow negative by $42.4 billion, and its shares fell about 6%. Grade B. Wrong if: Our read is that investors will price Amazon by its cash flow, as they priced Alphabet. If Amazon closes above $243.79, its close before the results, by 6 November, the market has looked past the cash outflow and this file is wrong. https://causamarkets.com/edition/2026-10-29/https://causamarkets.com/edition/2026-10-29/Thu, 29 Oct 2026 06:00:00 GMTCausa DeskEditionThe Fed held at 3.75% to 4% with two officials voting to hike, and the 10-year yield closed above 5%.

Alphabet fell about 9% after hours on a profit miss, a second quarter of negative free cash flow and heavy borrowing. Grade B. Wrong if: Our read is that investors are marking Alphabet down for funding AI with borrowing rather than cash. If Alphabet closes above $321.89, its close before the results, by 6 November, the market has looked past the cash shortfall and this file is wrong. https://causamarkets.com/cause/fed-holds-two-vote-to-hike/https://causamarkets.com/cause/fed-holds-two-vote-to-hike/Thu, 29 Oct 2026 06:00:00 GMTCausa DeskCause FileUS 10-year Treasury yieldThe Fed held at 3.75% to 4%, but two officials voted to raise rates and the statement said inflation remains elevated. Traders kept about an 85% chance of a December hike, and the 10-year yield closed above 5%. Grade B. Wrong if: Our read is that the two dissents make a December hike the base case. If the Fed leaves its target range at 3.75% to 4% at its 9 December meeting, this file is wrong. https://causamarkets.com/edition/2026-10-28/https://causamarkets.com/edition/2026-10-28/Wed, 28 Oct 2026 09:00:00 GMTCausa DeskEditionDetails of Anthropic’s planned listing carried chipmakers higher for a third session, and our first test, F-010, held.

Microsoft and Alphabet report tonight, the first direct check on whether the spending behind the rally is paying back. Grade B. Wrong if: Our read is that the rally rests on AI spending that Microsoft and Alphabet will confirm. If the Nasdaq closes below 26,000 on a day the 10-year yield closes below 5.10%, by Friday 30 October, the results have not supported the spending case and this file is wrong. https://causamarkets.com/cause/brent-falls-fed-weighs-oil/https://causamarkets.com/cause/brent-falls-fed-weighs-oil/Wed, 28 Oct 2026 09:00:00 GMTCausa DeskCause FileBrent crudeBrent fell for a second session as Iran’s leadership reviewed talks with Saudi Arabia, Turkey and Pakistan. Attacks on shipping remain at record levels, and the Fed meets today with markets pricing a December hike that is hard to explain without oil. Grade B. Wrong if: Our read is that oil, not the labour market, is keeping the Fed on a hiking path. If the 10-year yield closes below 4.85% on a day Brent closes above $110, by 13 November, bond markets have stopped pricing oil-driven hikes and this file is wrong. https://causamarkets.com/edition/2026-10-27/https://causamarkets.com/edition/2026-10-27/Tue, 27 Oct 2026 18:00:00 GMTCausa DeskEditionAnthropic’s computing contract with SpaceX and chipmakers’ interest in Meta’s share sale lifted the Nasdaq about 1% for a second day.

Boeing’s results held back the Dow. Grade B. Wrong if: Our read is that the rally rests on committed AI spending, not on lower oil or hopes for easier rates. If the Nasdaq closes below 25,800 on a day the 10-year yield closes below 5.10%, by 6 November, the demand evidence has not held and this file is wrong. https://causamarkets.com/cause/brent-eases-iran-keeps-talking/https://causamarkets.com/cause/brent-eases-iran-keeps-talking/Tue, 27 Oct 2026 18:00:00 GMTCausa DeskCause FileBrent crudeBrent slipped again after Iran’s security council chief met Saudi, Turkish and Pakistani officials and all four agreed to keep talking. A Houthi claim of a missile hit on Saudi Arabia’s Ras Tanura refinery is unconfirmed, and the physical market remains tight. Grade B. Wrong if: Our read is that the Ras Tanura claim is a risk event, not a supply event. If Saudi Aramco or the Saudi government confirms damage that reduced output at Ras Tanura by 6 November, the attack was a supply event and this file understated it. https://causamarkets.com/edition/2026-10-26/https://causamarkets.com/edition/2026-10-26/Mon, 26 Oct 2026 18:30:00 GMTCausa DeskEditionAnthropic’s IPO filing quantified AI demand and lifted the Nasdaq about 1%.

Reports of a 6% fall compared two different contracts. The war premium remains in the price. Grade B. Wrong if: Our read is that the market heard the talks but does not yet believe them, so the war premium stays. If traders start pricing a settlement, the premium will drain. If US crude closes below $97, where it stood before last Wednesday’s strike near Shaybah, on any session by 3 November, election day, the market has begun to bet on a deal and this file misread it. We test on US crude because its front month does not change before the deadline. https://causamarkets.com/cause/anthropic-filing-lifts-chips/https://causamarkets.com/cause/anthropic-filing-lifts-chips/Mon, 26 Oct 2026 18:30:00 GMTCausa DeskCause FileNasdaq CompositeAnthropic filed to list on Nasdaq, disclosing $16.3 billion of first-half revenue and about $430 billion of committed spending with Broadcom, Google, Amazon and Microsoft. After a week of doubt about the return on AI spending, investors bought the suppliers. Grade B. Wrong if: If the filing changed the story rather than one afternoon’s mood, the gain should survive the next session, before the Fed decides and before Microsoft and Alphabet report. If the Nasdaq closes below Friday’s 25,955.34 on Tuesday 27 October, the rally was positioning and this file gave the filing too much weight. https://causamarkets.com/cause/gold-back-above-4000/https://causamarkets.com/cause/gold-back-above-4000/Mon, 26 Oct 2026 18:30:00 GMTCausa DeskCause FileGoldGold recovered above $4,000 after Friday’s fall to a three-month low. Kitco tied the morning bounce to cheaper oil, but oil recovered most of its fall while gold held its gain. Calmer equity markets, and less selling to raise cash, fit the full session better. Grade C. Wrong if: If forced selling was the cause, gold should not make new lows while stocks hold up. If spot gold closes below Friday’s low of $3,975 on a day the S&P 500 closes above 7,600, by 6 November, the selling is not about the stock market and this file is wrong. https://causamarkets.com/edition/2026-10-23/https://causamarkets.com/edition/2026-10-23/Fri, 23 Oct 2026 19:30:00 GMTCausa DeskEditionTalk of new strikes on Iran pushed Brent to a six-month high and pulled the Dow lower. Gold fell below $4,000, which puts Thursday's gold explanation on the edge of failing its own test. https://causamarkets.com/cause/oil-prices-a-wider-war/https://causamarkets.com/cause/oil-prices-a-wider-war/Fri, 23 Oct 2026 19:30:00 GMTCausa DeskCause FileBrent crudeBrent rose for a third straight week on reports that the US and Israel are weighing new strikes on Iran after the US midterms. No supply has been lost; the move is a premium for the risk of a wider war. Grade A. Wrong if: Our read is that oil now prices a wider war, not a passing scare. If Brent closes below $108, where it traded before Wednesday's Shaybah strike, on any session by 6 November, the market has judged the escalation risk overdone and this file overstated it. https://causamarkets.com/cause/gold-breaks-4000/https://causamarkets.com/cause/gold-breaks-4000/Fri, 23 Oct 2026 19:30:00 GMTCausa DeskCause FileGoldGold fell below $4,000 on a day Treasury yields stayed below 5%, the condition we set for Thursday’s rate explanation to fail. Our best explanation now is forced selling by investors covering losses elsewhere. The grade stays C. Grade C. Wrong if: If forced selling is the cause, gold should stop falling once stocks calm down. If gold closes below $3,900 on a day the Nasdaq closes above 26,000, by 13 November, the selling is not coming from the stock rout and this file is wrong. https://causamarkets.com/cause/oil-pulls-the-dow-down/https://causamarkets.com/cause/oil-pulls-the-dow-down/Fri, 23 Oct 2026 19:30:00 GMTCausa DeskCause FileUS stocksSelling rotated from chips to the broader market. Airlines fell on fuel costs, American Express on job cuts and a revenue miss, and Verizon on reports about SpaceX. Chips stabilised after Thursday’s worst Nasdaq session since June. Grade B. Wrong if: Our read is that rising oil is now the main weight on stocks, alongside AI doubts. If the S&P 500 closes above 7,757.17, its level before Meta reported, on any session by 6 November while Brent is still above $112, oil is not holding stocks back and this file is wrong. https://causamarkets.com/edition/2026-10-22/https://causamarkets.com/edition/2026-10-22/Thu, 22 Oct 2026 15:00:00 GMTCausa DeskEditionA drone attack near Saudi Arabia’s Shaybah oilfield took Brent to a five-month high, and Meta’s spending guidance hit tech.

No output was lost. The move is a risk premium on the chance that a future strike stops production. Grade A. Wrong if: Our read is that Thursday's rise is fear, not lost supply. If Saudi Arabia or Aramco reports a production loss at Shaybah or any other field from these attacks by 6 November, the cause was physical and this file is wrong. https://causamarkets.com/cause/meta-ai-spending-nasdaq/https://causamarkets.com/cause/meta-ai-spending-nasdaq/Thu, 22 Oct 2026 15:00:00 GMTCausa DeskCause FileNasdaq CompositeMeta beat on revenue and earnings but fell more than 6% after raising the low end of its capital spending range and guiding to much higher investment in 2027. With chips weak and oil rising, the Nasdaq more than reversed Wednesday’s gain. Grade B. Wrong if: If the Nasdaq Composite closes back above Wednesday's 26,702.86 by 30 October while Brent is still above $108, the drop was a one-session flush rather than a lasting verdict on AI spending. https://causamarkets.com/cause/bitcoin-gives-back-bounce/https://causamarkets.com/cause/bitcoin-gives-back-bounce/Thu, 22 Oct 2026 15:00:00 GMTCausa DeskCause FileBitcoinBitcoin opened at its highest level since 7 October and fell more than 3% as Brent rose above $111. The reported channel runs from oil to inflation expectations to Fed pricing, which weighs on risk assets. Grade B. Wrong if: If bitcoin closes above $84,000 by 29 October while Brent is still above $108, oil is not what is holding crypto down. https://causamarkets.com/cause/gold-falls-in-risk-off-session/https://causamarkets.com/cause/gold-falls-in-risk-off-session/Thu, 22 Oct 2026 15:00:00 GMTCausa DeskCause FileGoldGold fell despite a risk-off session that would normally support it. Our best explanation is the rate path: gold pays no yield while the Fed is still raising. The evidence is weak, and the file is graded C. Grade C. Wrong if: If gold closes below $4,000 on a day when the 10-year yield closes below 5.00%, falling rates are not rescuing it, and the rate explanation fails.
