A trading blog built around market dispatches, trade notes, and disciplined positioning. The writing sits first. Berkeley research and Parhelion sit underneath it as support, context, and implementation.

01 About

Equities.
Macro.
Discipline.

This site is where I publish market dispatches, trade notes, and research-backed views across equities, macro, and options structure.

The focus is disciplined positioning. Regime, valuation, catalysts, and risk definition matter before a view becomes a trade.

I study at UC Berkeley Haas, conduct research on global energy demand and supply forecasting, and run Parhelion Capital, where high-conviction written theses can move from deck to implementation.

02 Macro Markets

Macro notes covering regime shifts, fiscal dynamics, and cross-asset positioning. These longer pieces frame how I think about markets before getting into individual setups.

Market Dispatch · Macro February 20, 2026 Justin Chuk
The Soft Landing Consensus Is Partially Right and Dangerously Incomplete
What markets are missing is the distinction between a soft landing in the cycle and a structural deterioration in the regime. Three concurrent regime-level shifts — fiscal dominance, dollar reserve diversification, and the AI capex reality check — are underway simultaneously and only partially reflected in current prices.

Market Dispatch: What January Broke, and How February Should Be Traded
January ended flat on the surface but left markets with a harder message underneath: DeepSeek challenged AI valuation assumptions, the Fed shifted to a more cautious posture, tariffs moved from headline risk toward a real cost shock, and gold stopped behaving like a simple dollar inverse.

03 Trade Ideas

Individual trade write-ups with defined structure, entry, sizing, invalidation, and exit criteria. Each idea is a standalone note — not a recommendation.

Five Trades for a More Fragile Backdrop: Cash, Gold, KMB, CEG, and a SPY Hedge
A February trade book built around a less forgiving backdrop: flatter index upside, tariff pass-through risk, cleaner structural support in gold, selective AI power exposure, and downside protection where insurance is still reasonably priced.

With the S&P near 21.5x forward earnings and a shallower cut path, the risk-adjusted math tilts toward underweighting beta and parking capital in short-duration yield.

05 Parhelion Capital
Vancouver, BC · Incorporated February 2026
Investment process developed and actively refined since December 2022.
Parhelion LinkedIn →

Parhelion Capital was incorporated in Vancouver in February 2026, with the underlying investment process built and actively refined since December 2022.

I founded it to keep the structure simpler and more aligned. Rather than charging an ongoing management fee, the focus is on capital appreciation, disciplined implementation, and the long-run growth of net asset value per share.

I hold equity in the company, so incentives sit with outcomes. Redemptions are generally structured on a monthly or quarterly basis after an initial one-year lock-up, which can also support tax efficiency.

01
Incorporated
Established in Vancouver in February 2026, built on an investment process that has been active since December 2022.
02
Aligned Structure
No ongoing management fee. Incentives are tied to ownership and the long-term compounding of value.
03
Investment Approach
The fund focuses on capital appreciation through public equities, selective long and short positioning, and options where they improve structure, define risk, or express a view more efficiently.
04
Stock Deck Pitches
Internal stock pitch decks are not just academic exercises. High-conviction ideas are implemented in the fund when the thesis, valuation, and risk parameters align.
05
Research Process
All positions are preceded by structured pitch decks. Post-trade attribution is maintained across positions to review what worked, what did not, and why.
