1 · Universe construction
Every trading day at 19:30 IST we ingest the AMFI NAV file, reconcile it against our canonical scheme master, and build a clean fund universe. Direct plans only — regular plans are visible but not recommendable. Schemes younger than 36 months are surfaced with a freshness flag, never as a buy signal.
“A clean universe is the precondition for an honest recommendation. Most of the work is here, and most of it is invisible.”
2 · Fund scoring
Each fund receives a daily score on a 0–100 scale, composed of a weighted blend of risk-adjusted return (Sharpe, Sortino, Calmar), peer-rank consistency over rolling 1y / 3y / 5y windows, and a downside-capture penalty. Scores never reset — the previous fourteen days are always visible alongside the current value.
| Component | Weight | Window |
|---|---|---|
| Risk-adjusted return | 40% | 3y / 5y blended |
| Peer-rank consistency | 25% | Rolling 1y / 3y / 5y |
| Downside capture | 20% | 3y |
| Expense efficiency | 10% | Latest |
| Manager continuity | 5% | Latest |
3 · Suitability gate
Every recommendation is checked against the client's recorded risk profile, time horizon, and current concentration. A high-scoring small-cap fund will not surface as a buy signal for a conservative client with a 3-year horizon, regardless of its score. The gate is conservative by design.
4 · Compliance rules
Eighteen coded SEBI rules run before any recommendation is ever shown — concentration limits, churning velocity, ELSS lock-in awareness, KYC currency, and fourteen others. Each rule writes a pass / fail / blocked record into the audit ledger, with the rule version and the input snapshot.
5 · Audit posture
Every advisor action — recommendation viewed, approval granted, export downloaded, override applied — is appended to a hash-chained ledger. The ledger is read-only by design; corrections are written as forward-dated reversals, never edits. This is the trail an inspection lands on.
6 · What Zyphr does not do
Zyphr does not place trades, does not custody assets, and does not generate sales-pitch content. Execution remains in BSE Star MF, NSE NMF II, or MFU — wherever you are placing trades today. Zyphr is the layer that prepares, gates, and records.
