The Firm
Human judgment, machine precision.
Sephiance Qant is an institutional research house built on a proven quantitative engine. Refined through continuous optimisation and tuning, the platform operates across three research divisions. Every number is produced by a deterministic engine grounded in published mathematics. Every input is cross-referenced across multiple sources, independently verified, and overlaid with our own proprietary analysis before it informs a conclusion.
The result combines the breadth and speed of cutting-edge AI with the discipline and reproducibility of institutional quant, delivered on demand.

Structure
Three research desks, one decision
Sephiance Qant covers five asset classes: equities, fixed income, commodities, currencies, and crypto, across three dedicated research divisions. Each division operates independently, then passes its output to the founder, who sets the house view and makes the final call before anything reaches a client.
IDivision
Asset & Wealth Management
Equity and portfolio research for client capital. Builds fundamental coverage on single names, constructs and optimises multi-asset portfolios, and maintains ongoing performance surveillance against mandate benchmarks.
- Single-name equity research with DCF, multiples & comps
- Multi-asset portfolio construction & risk-budgeting
- Performance attribution & track-record verification
- Custom screening & watchlist generation
IIDivision
Global Banking & Markets
The markets desk covers all five asset classes: equities, commodities, FX, crypto, and macro. Cross-asset surveillance is augmented by a dedicated Greek-market specialist who contributes local on-the-ground intelligence.
- Equities, commodities, FX, crypto & macro coverage
- Central-bank policy, yield-curve & rotation analysis
- Greek-market specialist desk with local sources
- Earnings, sentiment & relative-value surveillance
IIIDivision
Risk
Independent quantitative oversight. Every thesis, signal, and recommendation from Divisions I and II is validated here through point-in-time backtesting, factor decomposition, and automated quantitative checks before any output is cleared for release.
- Point-in-time strategy backtesting with transaction costs
- Multi-factor exposure & signal-quality screening
- Volatility regime & anomaly detection
- Portfolio-level stress testing & scenario analysis
IVDivision
Principal Oversight
Above the three research divisions sits the founder, whose background spans private equity boutiques and family offices, with deep grounding in quantitative finance, portfolio management, and cross-asset markets. Every research output from Divisions I, II, and III (every report, every signal, every recommendation) passes across his desk for final review before a single call is released to a client.
The Trade Desk
Our traders, every single day
Behind every report is a team of specialised agent-analysts that runs a full desk cycle each trading day. They do not simply summarise the news. They take a position, size it, defend it against an independent risk committee, and only then release a call.
+0.4%average increase per day
Market Intelligence, at the open
Before the bell, the desk takes in live prices, global news and sentiment across equities, commodities, FX, rates and crypto, and reads the broader macro climate.
The division analysts debate
Asset & Wealth, Global Banking & Markets and the Greek-market specialist each run their analysts, then argue bull against bear. Disagreement is the point: a thesis that cannot survive the debate never reaches the trader.
The trader takes a position
The Trade Desk turns the winning thesis into a real proposal: a clear direction, a disciplined entry, a sized stake and defined risk limits. Every call is logged and held accountable to what the market actually did.
Risk committee signs off
An independent committee, covering market, credit, liquidity, model and operational risk, stress-tests the trade and can veto it. Only trades that clear risk move forward.
Founder review, then release
Every cleared call crosses the founder's desk for a final read before it reaches a client, exactly as a bulge-bracket desk operates.
The desk learns overnight
After the close, the proprietary Sephiance algorithm learns from how the day's calls played out and adapts the desk, so tomorrow's traders start sharper than today's.
Quantitative Edge
Proven mathematics, not just language
Most market tools, and most AI products, stop at narrative. Sephiance Qant does not. Every number in a report is produced by a deterministic engine built on published, peer-reviewed mathematics, the same toolkit used on institutional quant desks: Monte Carlo simulation, Hidden Markov regime detection, Gaussian Process forecasting, PCA factor decomposition, cointegration testing and more. But the published models are only the foundation. What truly sets us apart is the proprietary Sephiance algorithm that sits above them, refined over more than a decade of live trading and continuously adapting the entire engine to real markets. Its inner workings are our own and are not disclosed. The underlying methods are established and reproducible; the way we combine, weight and evolve them is not. Language explains the result. Mathematics produces it.
The Sephiance Algorithm
One self-learning algorithm sits above every model
The published mathematics is only the foundation. Above it sits the Sephiance algorithm, a proprietary self-learning layer developed and refined over more than a decade of live trading. It continuously measures the engine against real market behaviour and adapts it, so the system producing tomorrow's research is never quite the same as today's. How it decides what to change, and how the many models are weighted and reconciled into a single call, is the core intellectual property of Sephiance Qant and is deliberately not disclosed. What matters to you is the outcome: every figure you receive is the product of the whole engine, unified and continuously sharpened, never one model's isolated guess.
Learns from live market behaviour
Adapts the whole engine, not single models
Sharpens with every cycle it runs
Proprietary — and never disclosed
10+ yrs of market data
10,000+ simulated paths
14 peer-reviewed theories
Daily full re-optimisation
1 self-learning algorithm
Deterministic, reproducible, auditable. Narrative explains a call, but it never overrides the mathematics. Where the two disagree, the conflict is flagged and surfaced rather than smoothed over.
The Software
The Sephiance Qant Terminal
Our research runs on a proprietary institutional terminal: a single, live command-line cockpit for cross-asset markets, intelligence, and the full quantitative engine.
This terminal has been the backbone of my personal portfolio for the past ten years. Every model, every signal, every data feed was built for my own capital first. It has delivered an average yearly return of over 55%, reaching 400% in certain unique market situations, and has been stress-tested through multiple market regimes. I am now opening it for commercial use.
Live multi-asset coverage
Real-time futures, world indices, commodities, rates, FX and crypto, alongside global market hours, in a single live view.
Institutional command line
A Bloomberg-style interface: type a ticker and a code (AAPL GP, MSFT DES) to drive twenty-one analysis functions instantly.
Real-time data & intelligence
Institutional-grade market, news and macro data, unified into a single live view.
The same multidivisional engine that powers every Sephiance Qant report, exposed as a working terminal. Ten years of personal use, now available for commercial deployment. Proprietary, confidential, and built for institutional use.
