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.

It is shaped by my research at the University of California, Haas School of Business and carried into live positioning through Parhelion Capital.

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: The Soft Landing Consensus Is 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: Beneath a Flat January, the Market Shifted
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.

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.

SPY / Cash
Hold Cash Instead of Forcing Broad Index Exposure
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.

Gold as the Cleaner Structural Long
Gold held its bid even against dollar strength. That combination usually signals structural demand, with tariff-driven stagflation risk adding another layer to the long.

Carry Downside Protection While Insurance Is Still Reasonable

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

I founded Parhelion Capital to make serious investment work accessible in a more aligned format. Many retail investors do not have access to the level of research, underwriting, and disciplined implementation that typically supports institutional capital.

Parhelion is built around written theses, valuation, structure, and risk-defined positioning. The process was built and refined from December 2022 and formally incorporated in Vancouver in March 2026.

My incentives are tied to outcomes, with capital aligned alongside the strategy and the emphasis placed on long-run growth in net asset value.

01
Incorporated
Established in Vancouver in March 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.
