What is Pengyi OS
A durable record of how thinking becomes action.
Original material stays private. Reviewed abstractions become connected notes, decisions, systems, projects, and measurable next actions.
Strategic spine
The Leverage Stack
Capability creates results. Results create capital and allocation power. Those assets reopen the system at a higher level of capability and choice.
Read the operating principleCore systems
One foundation. Multiple domain teams.

PENGYI-01
The primary A500 multi-factor index-enhancement research line, progressing through evidence gates rather than return claims.
ResearchSignal
Trend Following
A portable multi-asset signal framework awaiting independent evidence gates.
Long horizonExecution
Microstructure
Order-book, inventory, spread, and execution research under simulation-only boundaries.
Latest public notes
Private sources. Reviewed abstractions.
The Leverage Stack
AI-native capability compounds when real results become capital, allocation power, larger opportunities, and renewed technical capacity.

Balance Sheet, Liquidity, Survival
Cash flow, liquidity, duration, financing cost, and survival constraints precede leverage or return targets.
