SVIX · Bearish synthetic + hedge · ATM synthetic, hedge 0.5 %

Historical bid/ask model

Protected synthetic position: three options, no premium-ratio filter

Bullish: buy a Call and sell a Put at the same nearest ATM strike K; buy a protective Put below K. Bearish: buy a Put and sell a Call at K; buy a protective Call above K. All three have the same expiry. The hedge targets 0.5% from K on the listed strike grid, not from the underlying price.

The sold option is not assumed to pay for the bought option. Signed entry credit = sold premium − both bought premiums; a negative value is an actual opening debit. Signed exit debit is positive when paid and negative when received. P&L = (entry credit − exit debit) × 100 − all six commissions.

The bullish upside has no strike cap; bearish gains are not capped by the hedge width but have a natural limit at an underlying price of zero. Theoretical maximum expiry loss is (distance from K to the hedge − signed entry credit) × 100 + fees. This does not guarantee that quoted closing costs stay inside the expiry payoff bounds.

Stress lowers the sold entry premium by 10% and raises both bought entry premiums by 10%. It always worsens the entry, including a net debit. Exit quotes and displayed original leg quotes are unchanged. There is no take-profit rule or 0.5% stop in these new scenarios.

Average profitable trade: —; Average losing trade: $-269.08. One three-option set, after fees, under the selected price assumption.

On 9 days even one option set exceeds the expiry-risk budget, so quantity is zero. Those days remain in the one-set table but not in the budget-sized result.

Contracts are selected from the SVIX chain available on the entry date: the nearest standard expiry within 0–7 calendar days, without switching to a later expiry to improve quotes. All three positions close in that SAME session at the opposite bid/ask. Remaining time value is included; intrinsic value is never substituted.

If a bought option has no positive executable bid at exit, the three-leg close is unverified: no sale at zero and no overnight carry are invented. Later sessions remain independent trade estimates, not a verified continuous account path.

The latest quote from the current regular session is used, even if unchanged for several minutes. Its actual timestamp is available on each option. Historical quotes do not guarantee simultaneous execution of all legs.

Commission per option at entry and again at exit: $0.65. Three entries plus three exits: six commissions per set.

Published data period: 2026-01-01 to 2026-09-04.

Displayed prices are historical quotes, not confirmed simultaneous fills. Commissions apply on entry and exit. Early assignment, stock delivery, intraday stops, and financing are not simulated. Risk at expiry is theoretical; quoted closing costs can exceed the spread width.

Data coverage: 116 entries; 82 closed; 0 still open; 34 missing an exit quote.

Skipped entry opportunities: 54 for market data or contract checks; 0 without an expiry in the selected window. Counts use the selected ticker, strategy and shape.

The result is incomplete: missing exit quotes remain visible and their unknown P&L is excluded from totals.

For 6 closed trades, exit quote size cannot support the budget-sized position. The scaled total is incomplete; these trades remain in the one-contract results.
