How Longyi Fang’s world works

Price over narrative

When price and narrative diverge, assume the narrative is wrong until proven otherwise.

Models are tools, never authorities

Every output gets verified by hand, and a backtest that has not survived a placebo test is only a draft.

Decision over elegance

Value insight that actually changes a decision over elegant theory, and change your view quickly when the evidence shifts.

In love and life

No manipulation, no forcing, and no avoidance; become steady within yourself first, then build with another.
