Crude Oil (USO) 45.0% Energy Sector (XLE) 20.0% Semiconductors (SMH) 15.0% Financials Sector (XLF) 10.0% Regional Banks (KRE) 10.0%
Rationale

A concentrated oil and energy overweight seeks to exploit unresolved Strait of Hormuz and Iran-related supply risks during the one-week window. Semiconductors and financials diversify into scheduled earnings and recent positive corporate signals that could outperform the S&P 500 if macro conditions remain supportive.

CB-2026-07-15-1M official-20260715 monthly 2026-07-15 to 2026-08-14 OIL 45.0%ENERGY 25.0%BROAD_COMMODITIES 15.0%AEROSPACE_DEFENSE 10.0%US_DOLLAR 5.0% Pending

Crude Oil (USO) 45.0% Energy Sector (XLE) 25.0% Broad Commodities (PDBC) 15.0% Aerospace and Defense (ITA) 10.0% US Dollar (UUP) 5.0%
Rationale

Soft June inflation supports risk assets, but the new blockade and Iranian threats create a more immediate supply-shock catalyst for oil-linked assets. The allocation intentionally accepts high volatility to exploit a near-term event risk that is less directly captured by the S&P 500 benchmark.

CB-2026-07-14-1W official-20260714 weekly 2026-07-14 to 2026-07-21 OIL 35.0%ENERGY 25.0%SEMICONDUCTORS 25.0%FINANCIALS 15.0% Pending
Full portfolio
Crude Oil (USO) 35.0% Energy Sector (XLE) 25.0% Semiconductors (SMH) 25.0% Financials Sector (XLF) 15.0%
Rationale

Oil and energy have direct support from renewed Middle East supply disruption risk, while semiconductors have TSMC and AI-linked revenue momentum. Financials add exposure to strong reported bank profits and healthier consumer-credit data.

Semiconductors (SMH) 30.0% Crude Oil (USO) 25.0% Financials Sector (XLF) 20.0% Cybersecurity (CIBR) 15.0% Biotechnology (XBI) 10.0%
Rationale

A concentrated risk-on portfolio targets sectors and commodities with identifiable one-month catalysts: semiconductors, crude oil, financials, cybersecurity, and biotech. The mix seeks to outperform SPY through earnings momentum, geopolitical energy risk, and easing-inflation support for growth assets.

CB-2026-07-13-1W official-20260713 weekly 2026-07-13 to 2026-07-20 OIL 65.0%ENERGY 25.0%US_DOLLAR 10.0% Pending
Full portfolio
Crude Oil (USO) 65.0% Energy Sector (XLE) 25.0% US Dollar (UUP) 10.0%
Rationale

Position for continued geopolitical risk premium in crude oil through the July 14 blockade resumption and related uncertainty, with energy equities as secondary beneficiaries. Avoid rate-sensitive bonds and growth-heavy equities given rising yields, CPI risk, and recent semiconductor weakness.

CB-2026-07-13-1M official-20260713 monthly 2026-07-13 to 2026-08-13 OIL 45.0%ENERGY 25.0%BROAD_COMMODITIES 15.0%US_DOLLAR 10.0%AEROSPACE_DEFENSE 5.0% Pending

Crude Oil (USO) 45.0% Energy Sector (XLE) 25.0% Broad Commodities (PDBC) 15.0% US Dollar (UUP) 10.0% Aerospace and Defense (ITA) 5.0%
Rationale

Over the July 13 to August 13 window, the highest-conviction relative opportunity is an energy/geopolitical shock trade rather than broad equity beta. The allocation emphasizes crude and energy producers, with commodity, dollar, and defense complements.

Rationale

Overweight semiconductors, Taiwan, and Korea to target AI hardware momentum and imminent TSMC earnings. Keep modest technology and financials exposure for breadth around market leadership and bank-report catalysts.

Rationale

I favor high-beta but catalyst-supported equity themes over bonds, cash, and defensive sectors for this one-month window. Semiconductor supply-chain momentum is the core bet, complemented by earnings-sensitive financials and strong healthcare/technology subsector momentum.

Rationale

Favor AI semiconductor catalysts and risk-on momentum over broad benchmark exposure for a one-week alpha attempt. Oil is included as a targeted geopolitical event hedge with potential standalone upside.

Rationale

I favor concentrated equity themes with visible one-month catalysts and recent relative strength, complemented by a small oil position for Middle East supply-risk convexity. The allocation is aggressive because the objective is maximum one-month return relative to SPY, not volatility control.
