Institutional Research
Quantitative research,
engineered like a bank.
A full institutional research desk across three research divisions, covering equities, commodities, FX, crypto and macro on demand.
Human judgment, machine precision.
Sephiance Qant is an institutional research house that pairs frontier artificial intelligence with a proven quantitative engine. Refined through continuous optimisation and tuning, the platform deploys advanced AI agents, powered by the highest-tier large language models, across three research divisions. They read data, reason, and debate, while a deterministic engine grounded in published mathematics produces every number. 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.
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.
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
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
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
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.
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. The methods are established and reproducible: identical inputs return identical outputs, every result is auditable, and nothing rests on a model's opinion. Every model is calibrated and tested on more than ten years of historical market data. Language explains the result. Mathematics produces it.
Monte Carlo Forecast
Geometric Brownian Motion over 10,000+ paths to simulate price distributions and confidence intervals.
Regime Detection
Hidden Markov Model classifies market states (calm, normal, turbulent) from volatility dynamics.
Kelly Criterion
Optimal position sizing from full and half-Kelly formulas, grounded in information theory.
Kernel Regression
Nadaraya-Watson estimator with Gaussian kernel and AIC bandwidth selection for fair-value estimation.
Two-Stage DCF
Intrinsic valuation across bear, base, and bull scenarios with sensitivity analysis on key drivers.
Risk Metrics
Sharpe, Sortino, Calmar, VaR, CVaR, max drawdown, and annualised volatility from historical data.
Entropy Signal
Shannon entropy of return sequences measures directional bias and pattern predictability.
Mean Reversion
Z-score versus rolling SMA identifies overbought and oversold regimes for tactical calls.
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 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
Direct feeds from Tiingo, FMP, AlphaVantage, NewsAPI and FRED, with live global news and macro built in.
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.

Ioannis Tzalas
Founder and chief executive of Sephiance Qant, which he architected end to end. He built the firm's four-division structure, the proprietary quantitative engine that powers it (regime detection, Monte Carlo simulation, discounted cash-flow and multi-factor models), and its dedicated Greek-market specialist desk.
Every year I have spent in quantitative finance and technology has gone into optimising this terminal. Every model, every data feed, every line of infrastructure was designed, tuned and integrated with a single goal: to build something that simply does not exist anywhere else. No platform combines deterministic quant mathematics, multi-agent AI debate, live cross-asset data, and institutional governance in a single cockpit. There is nothing on the market that matches what this terminal delivers.
It is as advanced as it gets. And it is ours.
“Everyone should have access to a high-end terminal and the data they need to make informed fiscal decisions, without having to go through gatekeepers.”
