Strip
A systematic options approach—Strip—defined by explicit rules, testable on history, and fragile when costs or regimes change.
Overview
This is a volatility strategy consisting of a long position in an ATM call option, and a long position in two ATM put options with a strike price K.
Strip sits in the Options chapter of the systematic catalog. On QUSXFI we treat it as a testable hypothesis: specify entries, exits, sizing, and costs—then ask whether edge survives out-of-sample scrutiny.
Discretionary traders often arrive at similar ideas intuitively; the quantitative version forces you to write the rule before you see the next bar. That discipline is what makes results reproducible—or exposes them as luck.
Based on the research catalog 151 Trading Strategies (Kakushadze & Serur, 2018), section 2.35. Educational summary—not a replication of the full formal definition.
How the Strategy Works
Strip in Options is defined by explicit positions and transition rules—translate each clause into code or a checklist.
The published definition of Strip (catalog §2.35) specifies when exposure changes; discretionary overrides invalidate systematic claims.
Implementation and Research Process
Decompose Strip into signal, portfolio construction, and execution modules—each must be path-independent given the same historical tape.
Log regime tags beside Strip performance slices—vol level, rate cycle, liquidity stress.
Anchor Strip research to the catalog definition, then stress every assumption the textbook silently skips.
Risk: What Breaks This Strategy
American exercise, dividends, and pin risk are absent from naive Strip backtests but present in live options books.
Vol surface moves can hurt even when direction is right—the greek you ignored dominates.
Assignment alters stock delta when you planned to stay options-only.
Common Mistakes to Avoid
- Changing Strip parameters after each losing week—implicit discretion destroys reproducibility.
- Erasing losing Strip months instead of documenting regime breaks—that is how research firms stop learning.
- Using academic §2.35 definitions for Strip while ignoring borrow, margin, or contract specs.
- Confusing this educational Strip summary with compliance-approved investment advice.
How to Study This Strategy
- Compare Strip to one sidebar alternative net of costs—document why you chose this structure.
- List every data field Strip needs in Options; verify point-in-time integrity.
- Add conservative costs to Strip; rerun with 2× spreads and compare drawdown paths.
- Map Strip to Basic Trading chart concepts you will use as filters—not as substitutes for rules.
- Write a one-page Strip failure memo: three break modes and early warning signs.
Key Takeaways
- Strip in Options is a testable rule set—a systematic options approach—strip—defined by explicit rules, testable on history, and fragile when costs or regimes change.
- Translate every clause of Strip into code or a checklist; judgment steps are not yet quantitative.
- Capacity for Strip appears only when you simulate participation against average volume.
- Changing Strip parameters after each losing week—implicit discretion destroys reproducibility.
- Related strategies in the sidebar may share hidden exposures with Strip—compare before stacking.
Learning Tip
Build a 'Strip' research memo: hypothesis, universe, parameters, costs, kill switches—edit it before every tweak.
