Collar
A systematic options approach—Collar—defined by explicit rules, testable on history, and fragile when costs or regimes change.
Overview
“fence”) is a covered call augmented by a long put option as insurance against the stock price falling. 32 It amounts to buying stock, buying an OTM put option with a strike price K1, and selling an OTM call option with a higher strike price K2.
Collar 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 2.53. Educational summary—not a replication of the full formal definition.
How the Strategy Works
Collar in Options is defined by explicit positions and transition rules—translate each clause into code or a checklist.
The published definition of Collar (catalog §2.53) specifies when exposure changes; discretionary overrides invalidate systematic claims.
Implementation and Research Process
Walk-forward or hold-out test Collar; report turnover, max drawdown, and exposure—not CAGR alone.
Log regime tags beside Collar performance slices—vol level, rate cycle, liquidity stress.
Paper-trade Collar through a full signal cycle before live sizing.
Risk: What Breaks This Strategy
American exercise, dividends, and pin risk are absent from naive Collar 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 Collar parameters after each losing week—implicit discretion destroys reproducibility.
- Deploying Collar live before paper trading through at least one adverse Options month.
- Reporting Collar backtests without fees, slippage, and realistic fill rules.
- Using academic §2.53 definitions for Collar while ignoring borrow, margin, or contract specs.
How to Study This Strategy
- Map Collar to Basic Trading chart concepts you will use as filters—not as substitutes for rules.
- Compare Collar to one sidebar alternative net of costs—document why you chose this structure.
- Write a one-page Collar failure memo: three break modes and early warning signs.
- List every data field Collar needs in Options; verify point-in-time integrity.
- Add conservative costs to Collar; rerun with 2× spreads and compare drawdown paths.
Key Takeaways

- Translate every clause of Collar into code or a checklist; judgment steps are not yet quantitative.
- Capacity for Collar appears only when you simulate participation against average volume.
- Changing Collar parameters after each losing week—implicit discretion destroys reproducibility.
