Single-Stock Options: How to Trade Equity Options Internationally

Single-stock options provide leveraged, defined-risk, non-linear exposure to individual companies. The largest options market in the world is in US-listed equity options, AAPL, TSLA, MSFT, NVDA, AMZN, META all trade with deep options books going out years. For global traders, US single-stock options are accessible through international brokers and form the backbone of equity derivatives strategies for global retail and institutional flow. This guide covers contract structure, the major strategies, and the practical access path.

US single-stock options: contract specs

The OCC (Options Clearing Corporation) clears all US-listed equity options. Standard specifications:

• Contract size: 100 shares of the underlying.
• Style: American (exercisable any time before expiry).
• Settlement: Physical delivery on exercise. Most options are closed before expiry without exercise.
• Quote convention: USD per share. A call option quoted at $2.50 = $250 premium per contract (100 shares × $2.50).
• Expiries: Weekly, monthly (third Friday), quarterly, LEAPS (long-term options going out 1-3 years).
• Strikes: Wide menu, with strike intervals tighter near the current price and wider further out.

For a position trader looking at AAPL at $220, available strikes might run $200, $205, $210, $215, $217.50, $220, $222.50, $225, $230, $235, $240 across multiple expiries.

European single-stock options

Eurex lists single-stock options on most large European stocks plus many large US stocks. Key differences from US options:

• Style: Mostly European (exercisable only at expiry).
• Contract size: Typically 100 shares.
• Settlement: Physical or cash, depending on contract.
• Liquidity: Generally thinner per name than US options, except for the largest European blue-chips.

For European stocks, Eurex single-stock options provide native exposure. For US stocks held through Eurex options, the structure is similar but with the European-style early-exercise distinction.

Other regional venues, Euronext (Amsterdam, Paris, Brussels), LIFFE (London), Borsa Italiana, list options on regional stocks with their own specifications.

Strategy patterns

Long calls and long puts

The simplest options trades. Long calls profit from upside; long puts profit from downside. Maximum loss is the premium paid. Useful for high-conviction directional views with defined risk.

Practical example: A trader expects AAPL to move from $220 to $260 over the next quarter. Buying a 3-month $230 strike call for $8 premium provides $0 to ~$30 upside (asymmetric). Maximum loss = $800 per contract.

Covered call (income strategy)

Hold long stock, sell out-of-the-money call against it. Generates income (the call premium); caps upside at the strike. The classic income strategy for traders who hold stock long-term and accept giving up upside above a chosen level.

Practical example: Hold 100 AAPL at $220, sell 1-month $235 strike call for $2.50 premium = $250 income per month. If AAPL stays below $235, keep stock plus premium. If AAPL ends above $235, stock called away at $235 (still profitable, but capped).

Cash-secured put (entry strategy)

Sell out-of-the-money put on a stock you want to own. Receive premium. If the stock drops to the strike, you buy the stock at an effective price = strike - premium. If the stock stays above the strike, keep the premium.

Combined with the covered call cycle, this becomes the "wheel", a recurring income strategy. See wheel strategy AAPL for the full mechanics.

Iron condor (range-bound income)

Sell out-of-the-money call spread + sell out-of-the-money put spread. Defined risk. Profits if the stock stays within a range.

Practical example with TSLA at $240: Sell 1-month $260/$270 call spread + sell 1-month $220/$210 put spread. Collect ~$3 net premium = $300 per condor. Maximum loss = $700 per condor (spread width $10 - $3 premium = $7 × 100 shares). See iron condor TSLA earnings for an earnings-event application.

Calendar spread

Long longer-dated option + short shorter-dated option at the same strike. Profits from differential time decay (theta) between the two expiries. Common neutral-volatility play.

Diagonal spread

Calendar spread with different strikes. Adds directional bias to the time-decay trade.

Straddle and strangle

Long call + long put. Same strike (straddle) or different strikes (strangle). Profits from large moves in either direction. Useful around binary catalysts (earnings, drug approvals, M&A decisions). Loses if the underlying drifts sideways.

Implied volatility and earnings

Single-stock options frequently price elevated implied volatility ahead of earnings reports. The IV crush after the earnings event is a recurring pattern: implied vol drops sharply once the binary catalyst passes, even if the actual move is small.

For traders, this creates two opposing setups:

• Long volatility ahead of earnings, pay elevated premium, hope for a large actual move.
• Short volatility into earnings, sell premium expecting IV crush, hope for a contained move.

Both setups have asymmetric risk profiles. Short-volatility positions (naked short calls or short puts) can blow up on outsized actual moves; long-volatility positions bleed if the move is contained.

The Greeks

Single-stock options Greeks behave conventionally:

• Delta, sensitivity to underlying stock price.
• Gamma, rate of change of delta. Highest at-the-money for short-dated options.
• Vega, sensitivity to implied volatility. Often the dominant Greek for short-dated single-stock positions.
• Theta, time decay. Bleeds long premium positions daily.
• Rho, sensitivity to interest rates. Less material for short-dated single-stock options than for long-dated index or rates products.

Global access

US-listed equity options are accessible through international brokers:

• Interactive Brokers, broadest global access; full US options chains, multi-leg spreads supported.
• Saxo Bank, US options on the multi-asset platform.
• DEGIRO, limited US options availability for European retail.
• eToro, basic options exposure for European/international clients.
• XTB, limited options availability in some jurisdictions.

For European stocks, Eurex single-stock options are accessible through IBKR, Saxo Bank, and most European-focused brokers.

Tax and regulatory considerations

Tax treatment of single-stock options varies dramatically by jurisdiction:

• UK, option gains typically capital gains; share-based income from covered calls may be treated as income.
• EU member states, varies widely; Germany taxes equity gains, France has specific PEA-eligible structures, Spain has different rules.
• South Africa, FSCA-regulated brokers; options gains typically capital gains; tax dispensations may apply for certain account structures.
• Brazil, CVM/B3 oversight; B3-listed equity options have specific Brazilian tax rules; offshore-traded US options have different treatment.

Local tax advice is essential for any active options trader.

Position sizing

Three guidelines that protect capital:

1. Define maximum loss per trade, for premium-paid trades, this is the premium. For premium-collected trades, define the maximum loss explicitly and size accordingly.
2. Cap aggregate options exposure, total options premium at risk should not exceed a defined percentage of account equity (commonly 5-10%).
3. Diversify across positions, concentration in a single underlying or a single strategy magnifies blowup risk.

Risks specific to single-stock options

• Earnings gap risk, overnight earnings releases can produce gaps that bypass stop loss orders.
• Liquidity in long-dated options, LEAPS bid-ask spreads widen materially.
• Pin risk at expiry, at-the-money options at expiry can settle either side of the strike.
• Assignment risk on short positions, short calls or short puts can be assigned at any time before expiry (American-style); traders should monitor in-the-money short positions, especially around dividends.
• Margin escalation in volatile regimes, brokers may raise margin requirements on short option positions.
