01 Strategy Overview

📐 Black-Scholes (1973) · Variance Risk Premium · Term Structure

The Options & Derivatives Fund exploits a well-documented market inefficiency: implied volatility (IV) systematically overstates subsequently realised volatility (RV) — a phenomenon known as the variance risk premium. By systematically selling options when IV/RV ratios are elevated and term structure is in contango, the strategy collects volatility risk premium from investors who pay above-fair-value for options as downside insurance.

The entry criteria are derived from a quantitative screening model that evaluates three signals simultaneously: (1) IV₃₀/RV₃₀ ratio ≥ 1.25 using Yang-Zhang volatility estimator, (2) term structure slope from front month to 45 DTE ≤ −0.00406 (contango / forward IV below spot IV), and (3) average 30-day option volume ≥ 1.5M contracts. Only trades meeting all three criteria are classified as "Recommended".

03 Execution Framework

01 Short Straddle / Strangle Sell ATM or OTM straddle/strangle 1–5 days before earnings with 45–21 DTE. Target premium ≥ 1× expected move.
02 Iron Condor (Capped Risk) Where vol is elevated but position sizing demands capped downside: 10-delta wings. Defined risk per trade.
03 Position Sizing Maximum 5% NAV per earnings event. Portfolio IV budget managed at 20% total delta-adjusted notional.
04 Exits Close at 50% max profit (Tastyworks rule) or 21 DTE, whichever comes first. Stop at 200% premium received.

07 Macro Positioning & Investment Thesis

Regime as at May 2026

A short-volatility strategy must be run differently when geopolitical tail risk is elevated. The Strait of Hormuz crisis is exactly the kind of fat-tailed, headline-driven environment that punishes naive premium-selling — so the fund's discipline shifts toward defined-risk structures, smaller sizing, and harvesting a richer premium, rather than reaching for yield by selling unprotected options.

The Premium Why the edge persists

The strategy monetises the persistent gap between implied and realised volatility — the variance risk premium documented by Carr & Wu (2009). Investors structurally overpay for protection, and selling that insurance has positive expected value over time. Crucially, in a higher-fear regime that premium is wider: elevated implied volatility means each option sold collects more, improving the risk-reward of every position the fund initiates.

The Discipline Defined risk in a fat-tailed market

The danger of short volatility is the rare, violent move — and a market exposed to a single chokepoint and live conflict has more of them. The fund manages this explicitly: favouring capped-risk iron condors over naked straddles when geopolitical risk is high, reducing position size during periods of headline risk (an oil-price gap can move the whole market overnight), and respecting hard exit rules. The Yang-Zhang (2000) estimator is used to gauge true realised volatility so the fund only sells when the implied premium genuinely compensates for the risk being underwritten.

Diversification A return stream uncorrelated to the rest

For the broader platform, the value of this sleeve is that its return profile is largely independent of the directional equity, credit and commodity bets elsewhere. Income from volatility decay does not depend on markets going up — only on them not moving more than the option market feared. In a year where the macro path is unusually uncertain, an uncorrelated, defined-risk income stream is a genuine portfolio diversifier.
