The take
Commodities and long bonds cushioned a week that saw emerging markets drop 1.3% and tech take its worst hit since spring. Over the past four weeks China's slowdown and tariff talk sent EM down 8.8% while Treasuries rallied nearly 3%. Year-to-date the commodity sleeve — up 52.5% — still defines 2026, offsetting every portfolio's modest equity drag and leaving balanced allocations ahead of their benchmarks.
The week at a glance
- This week — Commodities and bonds steadied portfolios as EM equities fell 1.3% and tech sold off hard.
- Past 4 weeks — EM lost 8.8% on China worries; Treasuries gained 3% as yields dropped.
- Year-to-date — The commodity rally — up 52.5% — has carried every allocation above its benchmark.
This week: commodities offset a tech rout and emerging-market weakness
The Nasdaq-100 dropped 0.76% as mega-cap communication stocks tumbled 4.4%, their worst week since May. Emerging markets fell 1.3% and gold lost 4.0%, but commodities climbed 1.1% and 20-year Treasuries rallied 1.6%, limiting damage across the board. Lean Balanced held flat, its 27% bond sleeve adding 39 basis points while its 10% EM position subtracted 14. The Dual Momentum strategies stayed almost unchanged — commodities and REITs contributed 43 bp combined, canceling out the equity sleeves' 34 bp loss. Tech exposure matters: QQQ's 0.76% decline was mild compared to communication services, where a regulatory headline drove the 4.4% drop. Readers holding Nasdaq satellites felt that drag directly; those in the tactical sleeves saw commodities absorb it.
Past 4 weeks: China slowdown and tariff headlines turned EM into the month's anchor
China's industrial output missed forecasts in September, and new U.S. tariff proposals targeting Asian exporters sent emerging-market equities down 8.8% over four weeks — the steepest slide since early 2025. Developed ex-US fell 3.9%. Commodities rose 4.5% and long Treasuries gained 3.0% as ten-year yields dropped below 4%. The Lean Balanced portfolio lost 1.4%, cushioned by its 27% Treasury position (contributing 79 bp) and 14% commodity weight (62 bp); its 10% EM sleeve subtracted 91 bp. Dual Momentum Pivot5 gave up 1.9% — its five-asset equal-risk allocation meant the EM loss (163 bp drag) overwhelmed the commodity gain (95 bp), illustrating how momentum can't escape a collapsing sleeve it still holds. The Nasdaq-100 dropped 5.4%, pulling every satellite allocation lower. For context, the S&P 500 fell only 1.5% — the tech concentration that lifted growth portfolios in H1 reversed this month.
Year-to-date: the commodity supply shock defines the year, lifting every strategy above water
Commodities are up 52.5% year-to-date, the result of coordinated OPEC cuts in Q1 and a surprise lithium squeeze in June. That single sleeve contributed between 7.2 percentage points (Balanced, 14% weight) and 18.4 points (Dual Momentum, 35% weight) to every portfolio. Equities delivered mid-teens gains — EM up 13.9%, S&P 500 up 12.3% — but bonds and gold both fell, long Treasuries losing 3.4% and gold down 7.5%. The Lean Balanced portfolio returned 9.6%, trailing its 11.5% benchmark because its commodity overweight couldn't fully offset the bond and gold drag. The tactical sleeves outperformed: Dual Momentum Pivot5 returned 13.3%, its top-five momentum rule keeping it in commodities, EM, U.S. equities, real estate, and away from the bond losses. Tech did well — the Nasdaq-100 gained 15.1%, XLK up 27.7% — but communication services collapsed 9.6% after regulatory scrutiny intensified in September, a reminder that concentration cuts both ways. Readers who added a 10–20% Nasdaq satellite to a balanced core saw that boost; those overweight communication platforms did not.
