93% of F&O traders lost money.
The valuation gap is why.

SEBI's September 2024 report: aggregate retail losses exceeded ₹1.8 lakh crore in FY22–FY24. Fair pricing has been invisible. Until now.

Fair Pricing is Invisible

Retail traders see traded prices — but the model-based fair value, derived from an arbitrage-free volatility surface, is completely hidden from them.

No Post-Entry Risk Tools

Every platform is built for trade entry and strategy building. Once in a trade, there is no live risk management, P&L attribution, or monitoring for retail users.

P&L is a Black Box

Traders cannot separate what moved their position: was it spot? Time decay? A vol level shift? Skew? Without attribution, every loss is a mystery.

Institutional Gap is Vast

Institutional desks have pricing models, vol surfaces, scenario engines, and attribution tools. Retail traders have payoff diagrams and intuition.

Cutting-edge analytics.
Retail accessibility.

Sigma Wealth Analytix was built to close a single, critical gap: institutional options desks have continuously calibrated volatility surfaces, stochastic pricing engines, and full P&L attribution. Indian retail traders have payoff diagrams and intuition. We fix that.

  • Risk-neutral valuation — the universal standard at every global derivatives desk
  • Stochastic volatility surface calibrated live from NSE market bid/ask data
  • Sub-second recalibration — analytics that keep up with live trading decisions
  • NSE-calendar-aware theta — accurate time decay to the business day
  • Same framework as institutional market makers — now available to retail India
  • Glass-box pricing — every number is provable, no black boxes anywhere

Five competitive wedges.
One unfair advantage.

WEDGE 01

Transparency

No retail platform in India exposes continuously calibrated, model-based fair value from a live vol surface in real time. Sigma does. Every price is explained, not just displayed.

WEDGE 02

P&L Attribution

Post-entry P&L decomposition across all risk factors: spot, time, vol level, skew, curvature, correlation. Retail traders can finally answer why their position moved — quantitatively.

WEDGE 03

Speed

Sub-second surface recalibration and risk refresh. Stale analytics in fast-moving options markets are nearly as dangerous as no analytics. Sigma stays live throughout the trade.

WEDGE 04

Risk Control Spectrum

From fully hedged and risk-averse to directional and leveraged — every structure is quantitatively controlled. Traders manage risk to their appetite, not their intuition.

WEDGE 05

Economics

Highly optimised compute architecture enables full cutting-edge analytics at the price of a cup of coffee per month. The moat is the engine, not the hardware — enabling huge reach across retail India.

INDIA-FIRST

Indian Market Context

Built for Nifty/BankNifty structure: protective put demand, weekly expiry vol crush, Budget/RBI/Fed event vol spikes — all handled correctly by the stochastic vol engine.

Stochastic vol.
Live surface.

The same class of models used by the world's largest derivatives desks. A continuous volatility surface calibrated live from market bid/ask — not isolated IV data points from individual options.

01

Parameterised Stochastic Volatility

Volatility is modelled as a random process — it rises, falls, mean-reverts. This matches how markets actually behave. Produces a coherent vol surface across all strikes and expiries simultaneously.

02

Continuous Arbitrage-Free Surface

Not disconnected implied vols — a continuous, arbitrage-free valuation surface. Every point is internally consistent. No calendar spreads or butterfly spreads can be arbitraged.

03

Sub-Second Live Recalibration

The surface is recalibrated in under one second from live NSE bid/ask data. Fair value, Greeks, scenarios, and attribution all stay current as markets move.

04

Full Risk Attribution

P&L decomposed into Vol Level, Slope, Curvature, Correlation — surface-aware Greeks that account for how vol moves as spot moves. Impossible under Black-Scholes.

How Sigma closes
the institutional gap.

Institutional desks abandoned Black-Scholes for live trading decades ago. Sigma brings that same evolution to Indian retail options traders.

Price is visible.
Value must be modelled.

Risk-neutral valuation converts opinion-heavy trading into market-implied mathematics. It strips out subjective views and returns the arbitrage-free price that rational agents collectively imply.

Price
₹127
What the market is trading. Driven by supply, demand, sentiment, and liquidity.
Fair Value
₹114
What the option is theoretically worth. Arbitrage-free, model-derived, objective.

  The gap between ₹127 and ₹114 is the actionable valuation insight — directional and measurable.

01

Probability Is Not Enough

A 70% probability of profit is meaningless if you're overpaying for it. Risk-neutral pricing answers the critical question: are you paying a fair price for that probability? Without this, high-probability trades can still be negative expected value.

02

Fair Value as Compass

Even if you disagree with the model, knowing risk-neutral fair value tells you exactly how far the market has deviated — and in which direction. That deviation is directionally actionable. It is the edge.

03

The Language of Institutions

Every major derivatives desk globally prices in the risk-neutral framework. It is the universal standard. Sigma brings this cutting-edge analytical anchor to the retail trader — for the first time in the Indian market.

Black-Scholes is
wrong by design.

Black-Scholes assumes constant volatility — the market immediately rejects this (the volatility smile exists). Sigma uses a parameterised stochastic vol engine that produces a continuous, arbitrage-free valuation surface.

Protective Put Demand on Nifty

OTM puts are structurally expensive due to institutional hedging demand. BS sees constant vol and misses this entirely. Stochastic vol captures put skew explicitly.

BS systematically underprices OTM puts on Nifty

Weekly Expiry Vol Crush

Near-expiry options experience rapid vol collapse — especially in weekly contracts. BS has no mechanism to model this. Stochastic vol mean-reversion handles it correctly.

BS overvalues near-expiry options

Event Volatility Spikes

Budget, RBI policy, US Fed events cause discrete vol jumps that BS cannot anticipate. Stochastic vol with jump components handles these realistically.

BS leaves traders exposed through events

Full Vol Surface

Continuous arbitrage-free surface across all strikes and expiries — not isolated implied vols.

Surface-Aware Greeks

Accurate Gamma, Vanna, Volga accounting for how the surface moves as spot moves.

P&L Attribution

Decompose P&L into Vol Level, Slope, Curvature, and Correlation contributions.

Multi-Index Coverage

All indices and stocks with liquid F&O are supported — not limited to a fixed set.

NSE Calendar Theta

Accurate time decay to the business day with full NSE holiday calendar awareness.

Stop guessing.
Start knowing.

Black-Scholes cannot separate what moved your position. Sigma decomposes every rupee of P&L into its source — live, per option, per position.

Delta and Gamma

Spot move contribution — how much your P&L came from the underlying moving, and how much from the curvature of that move.

Theta — NSE Calendar Aware

Accurate time decay to the business day. Not a naive clock subtraction — full NSE holiday calendar and IST market hours built in.

Vol Level, Slope, and Curvature

Full decomposition of vol surface movement: how much came from a parallel shift, from skew rotation, and from wing movements.

Correlation

For multi-leg positions, correlation between underlying movements contributes measurably. Sigma surfaces this contribution explicitly.

Why Stochastic Volatility Beats Black-Scholes in Indian Markets

Nifty options have specific structural features — protective put demand, expiry vol crush, event spikes — that Black-Scholes systematically misprices. Stochastic vol handles all three.

01 / FOUNDATION

Risk-Neutral Measure

Under the risk-neutral measure, every asset grows at the risk-free rate. The model strips out subjective views — returning the arbitrage-free price the collective market implies.

02 / SURFACE

Stochastic Volatility Surface

A continuous, arbitrage-aware valuation layer across all strikes and expiries. The surface turns scattered quotes into a tradable, coherent structure — not disconnected IVs.

03 / CALIBRATION

Live Market Calibration

The surface is calibrated continuously from live NSE bid/ask data. Sub-second recalibration means fair value stays current as markets move — not a static morning snapshot.

04 / ATTRIBUTION

Full P&L Decomposition

P&L is decomposed into Vol Level, Vol Slope, Vol Curvature, and Correlation components. Impossible under Black-Scholes. Standard practice at cutting-edge institutional desks — now at retail.

Common questions
answered.

What makes Sigma different from other options platforms?

Sigma uses a continuously calibrated stochastic volatility surface — the same class of models used by institutional market makers. Other retail platforms use static or manually updated Black-Scholes IVs. The difference is a live, arbitrage-free valuation map versus a collection of disconnected numbers.

What is risk-neutral valuation?

Risk-neutral valuation prices options by discounting payoffs under the market-implied measure — not your personal forecast. It strips out subjective views and returns the arbitrage-free price that rational agents collectively imply. It is the universal institutional pricing standard globally.

Why is Black-Scholes not sufficient?

Black-Scholes assumes constant volatility across all strikes and expiries — the market immediately shows this is wrong (the volatility smile exists). It systematically misprices Nifty OTM puts, near-expiry options, and cannot handle event vol spikes. Stochastic vol addresses all of these structurally.

What does P&L Attribution actually show me?

P&L Attribution decomposes your position's daily P&L into specific sources: how much came from delta (spot move), gamma, theta (time decay), vol level change, vol slope (skew shift), vol curvature, and correlation. You stop guessing why your position moved and start knowing precisely.

What does sub-second recalibration mean in practice?

The entire stochastic vol surface — calibrated across all live strikes and expiries — is refreshed in under one second. This means fair value, Greeks, scenarios, and attribution all stay current with the live market throughout the trading day, not the state it was in at open.

Is Sigma suitable for beginners?

Sigma is designed for traders who take options seriously. The platform is built to be transparent rather than opaque: every number is explainable, every metric is labelled, and the AI Chatbot guides you through the platform's capabilities. The first 2 months are free — pay just ₹99 for 3 months upfront.

What is the Enterprise partnership model?
