Psi Fi™ — The Behavioral Psychology of Your Trades

Psi Fi™ (ΨΦ) looks at your trade history from a behavioral finance lens — including FOMO chasing, panic selling, and churn. We flag repeated mistakes, classify your investor persona, and show what-if paths under value, momentum, macro, tactical, or disciplined FOMO rules.

Upload a brokerage export (CSV or XLSX). One file per run — not an accounting audit.

Educational model only — counterfactual paths use rule-based simulations on adjusted prices, not live fund track records. How the analysis works.

Behavioral Portfolio Intelligence

Scope caveat: this run uses a subset of portfolio trades. Treat style mix, mistakes, and what-if style comparisons as evidence from the uploaded sample, not a whole-portfolio conclusion.

Methodology & FAQ

Psi Fi (ΨΦ) is psychological finance: an educational trade-upload analyzer that classifies behavioral patterns, flags common retail mistakes, and compares your actual path to simplified what-if discipline rules. It is not investment, tax, or accounting advice.

How The Analysis Works

Trades are normalized from your CSV or XLSX, then scored for style mix (value, momentum, tactical, macro), retail personas (for example panic seller or churn rotator), and evidence-backed mistake flags. Counterfactual paths replay your window under stylized rules — index patience, momentum redeploy, weekly tactical exits, macro cash sleeves, and a cautionary FOMO chase — using adjusted close prices. Outcomes are compared to your actual replay and SPY buy-and-hold.

What File Should I Upload?

One brokerage trade export per run (CSV or XLSX, 5MB max). Standard E*TRADE, Fidelity, Schwab, and Vanguard exports work; use the on-page CSV template if column names differ.

Is This Personalized Investment Advice?

No. Outputs depend on the file you upload and simplified model assumptions. They are illustrations for learning, not recommendations to buy, sell, or hold any security.

Does This Replace A Tax Or Accounting Audit?

No. Psi Fi reads trade history for behavioral patterns only. It does not reconcile cost basis, wash sales, or tax lots.
