Market analysis tied to a moment: monthly reviews, summits, elections and commodity moves, with what each one does and does not imply for a portfolio. Reporting on what happened and the reasoning behind why it matters, not forecasts.

Lula won Brazil’s runoff with 51.79%. By Monday morning Ibovespa futures fell as much as 19.85%, the dollar fixing rose 11% and B3 halted share trading.
US stocks split as Brent settled at $116.72 and AI financing costs came into focus, while PHP2Shell, a Node.js RCE and the eMudhra certificate compromise exposed another cost of the AI economy.
The 10-year JGB closed at 3.11% on 7 October 2026, the highest since 1996, and was back at 2.82% on 2 November; the Bank of Japan held its policy rate at 1.25% on 30 October. The Bank still holds 47.9% of JGBs and is shrinking that stake, and on 24 September a 10-year Treasury hedged into yen yielded 2.30%, below the JGB.
On Shiller's CAPE, the S&P 500's earnings yield (2.44%) fell below the 10-year TIPS real yield (2.85%) on 24 September 2026, the first negative gap since at least 2003; on FactSet's forward P/E the gap is still about 2.4 points, roughly half its ten-year norm. Nearly all of the squeeze since 2021 came from higher real yields, not higher valuations.
In December 2023 Argentine prices rose 25.5% in a single month. In August 2026 they rose 1.7%. Two consecutive years of fiscal surplus, three rating upgrades between May and July, record oil output and a trade surplus five times larger than a year earlier took country risk from roughly 1,900 basis points to about 400 at its July low. The bond market has paid for most of that rebuild. Argentine growth — wages, consumption, earnings — has not been repriced yet, and that is the half still available.
The 10-year Treasury closed at 5.01% on 16 and 18 September 2026, the highest since July 2007, after the Fed's first hike in more than three years. Since 1 May the whole rise has been in real yields: breakeven inflation fell from 2.48% to 2.33%, while consumers now expect 4.6% inflation next year.
Midterm years usually drag before the vote and rally after it; since 1950 the S&P 500 has risen in the twelve months after all 19 midterms. 2026 has already broken the first half, up 12.5% to September 24, so the question is whether the second half holds with the Fed tightening and oil above $100.
The May 2026 Beijing summit was the first state visit to China by a sitting US president in nearly nine years, and it touched five issues that move markets: tariffs, technology export controls, agriculture, currency and Taiwan. For most portfolios the right response is position sizing, not repositioning around a single diplomatic event.
Paul Tudor Jones told CNBC in May 2026 that the AI rally has another year or two of upside but will end in a correction he called breathtaking, comparing the moment to late 1999. Four indicators support the bubble reading and four argue this cycle genuinely differs. The practical response is trimming concentration, not exiting.
Equity indices reached record highs in May 2026 while war, oil and gold reshaped the risk picture underneath them. The month is a useful case study in how geopolitical shocks actually transmit to portfolios: through energy prices, safe-haven flows and rate expectations, rather than through the headlines themselves.
