Seagull Spread

A seagull provides directional exposure at zero cost (or even a credit), while buying a call requires paying a premium. The tradeoff is that your profit is capped (by the short call in the spread) and you take on risk from the naked put. Seagulls are ideal when you have moderate directional conviction and want to establish a position without spending capital, while accepting the risk tradeoff.

This is the main risk of a bullish seagull. If the stock falls below your short put strike, you'll face increasing losses as the short put gains intrinsic value. Your loss at expiration would be (Short Put Strike - Stock Price) × 100 minus any initial credit received. For example, if you sold a $560 put and the stock is at $540 at expiration, you'd lose $2,000 per contract (minus any credit received). This is why position sizing and stop losses are critical.

No. Seagulls include a naked short option (put for bullish, call for bearish), which requires margin. Even though the entry may be zero-cost, your broker will hold margin against the naked option because of its potential liability. You need both options approval for naked selling and sufficient margin in your account.

No, they're related but different. A risk reversal is just a long call + short put (bullish) or long put + short call (bearish) - unlimited profit potential on one side, unlimited risk on the other. A seagull adds a third leg (another short option) to cap the profit side, creating the vertical spread. This cap reduces potential gains but also reduces the net cost (often to zero).

SPY is ideal for your first seagull. It's the most liquid options market in the world, with tight bid-ask spreads across all strikes. This liquidity makes it easier to achieve zero-cost pricing and get good fills. Start with 1 contract to learn the mechanics before scaling up. Avoid individual stocks until you're comfortable with the strategy.

When the underlying approaches within 3-5% of your naked strike, you have several options: (1) Roll the naked option to a further OTM strike and/or later expiration - this typically costs money but reduces risk; (2) Close the entire position to crystallize the loss; (3) Convert to defined risk by buying an option to create a spread (e.g., buy a put below your short put). The key is to act before the strike is breached, when adjustment costs are still reasonable.

Bullish seagulls benefit from put skew - the phenomenon where OTM puts have higher IV than ATM or OTM calls in equity markets. This means the short put collects relatively more premium, making it easier to finance the call spread at zero cost. Bearish seagulls face the opposite: you're selling lower-IV calls and buying higher-IV puts, which can result in a net debit instead of zero cost.

Seagulls typically have positive theta because the naked short option (which has high theta) often outweighs the net theta of the spread. When the underlying stays in the neutral zone between the spread and naked option, time decay works in your favor. However, theta becomes less favorable (or even negative) if the underlying moves significantly toward either extreme, where one leg dominates the Greek profile.

Yes. If you reach 50% of max profit in the first third of the trade duration, strongly consider closing. This indicates a favorable move that may not continue, and you're capturing strong risk-adjusted returns. Conversely, if you're at 30% profit with only 7 days remaining, the risk-reward of holding for the extra 20% may not be worth the increased gamma risk.

SPX seagulls offer tax advantages (60/40 Section 1256 treatment), European-style exercise (no early assignment risk on the naked option), and cash settlement. SPY offers more granular strike selection, easier fills for smaller positions, and no cash settlement complexities. SPX is preferred for larger accounts seeking tax efficiency; SPY is fine for smaller positions and learning.

Enter seagulls when volatility is transitioning from elevated to normal (VIX declining from 25+ toward 18-20). This captures rich premium on the naked option while positioning for IV contraction that benefits your negative vega position. Avoid entries during low-to-high volatility transitions, which would hurt existing positions. Use VIX term structure (contango vs backwardation) to confirm regime: contango suggests stability favorable for seagulls.

Yes, you can delta hedge by buying/selling shares or futures to neutralize position delta. Consider hedging when: (1) Position delta exceeds your comfort zone (e.g., >0.50); (2) You want to isolate theta/vega exposure without directional risk; (3) You're approaching an event that could cause sharp moves. Hedging frequency is a tradeoff - too frequent erodes profits through transaction costs, too infrequent leaves you exposed to directional risk.

For 100 shares of stock, add: (1) Buy an OTM put for downside protection; (2) Sell a further OTM put to reduce protection cost; (3) Sell an OTM call to finance the put spread. This creates a defined downside (between the two puts), participation up to the call strike, and zero or near-zero cost. It's effectively a zero-cost collar with better downside protection structure. The tradeoff is giving up upside beyond the call strike.

Essential stress tests: (1) 10% overnight gap through naked strike - can you survive the loss? (2) VIX doubling from entry level - how much does the position lose? (3) Price at naked strike at 7 DTE - what's the gamma exposure? (4) Combined adverse move: 5% price move against + 30% IV increase. Ensure your position sizing allows survival of the worst-case scenarios while maintaining portfolio stability.

The algorithm should: (1) Start with target deltas (0.35 for long option, 0.20 for short spread option); (2) Calculate spread cost; (3) Iterate through short naked option strikes to find one with premium matching or exceeding spread cost; (4) Verify the selected naked strike has acceptable delta (0.25-0.35); (5) Check that the structure achieves zero-cost within $0.05. If no strike satisfies all conditions, widen the spread or wait for better volatility conditions.
