Wheel Strategy The Wheel is a popular income strategy that cycles between selling puts and covered calls: 1. **Phase 1:** Sell cash-secured puts at ${(config.targetDelta * 100).toFixed(0)}-delta 2. **If assigned:** Take delivery of shares at strike price 3. **Phase 2:** Sell covered calls against the shares 4. **If called away:** Return to Phase 1 5. **Repeat** **Key Parameters:** - Target Delta: ${(config.targetDelta * 100).toFixed(0)}-delta (${(config.targetDelta * 100).toFixed(0)}% probability of assignment) - Expiration: ${config.daysToExpiration} days (monthly) - Position Size: ${(config.capitalPercentage! * 100).toFixed(0)}% of capital per trade **Stats:** - Total Trades: ${wheel.stats.totalTrades} - Times Assigned: ${wheel.stats.totalAssignments} - Total Premium Collected: $${wheel.stats.totalPremiumCollected.toLocaleString(undefined, { maximumFractionDigits: 0 })} - Avg Premium/Trade: $${wheel.stats.avgPremiumPerTrade.toFixed(2)} --- ### 2. Covered Call Strategy Always hold SPY shares, continuously sell covered calls: 1. Buy initial SPY position 2. Sell ${(config.targetDelta * 100).toFixed(0)}-delta calls monthly 3. If called away, buy shares back immediately 4. Repeat **Stats:** - Total Trades: ${cc.stats.totalTrades} - Times Called Away: ${cc.stats.totalAssignments} - Total Premium Collected: $${cc.stats.totalPremiumCollected.toLocaleString(undefined, { maximumFractionDigits: 0 })} --- ### 3. Put Selling Strategy Pure premium collection without holding stock: 1. Sell ${(config.targetDelta * 100).toFixed(0)}-delta puts monthly 2. If assigned, immediately sell shares (don't hold) 3. Repeat This strategy has lower capital requirements but misses stock appreciation. **Stats:** - Total Trades: ${put.stats.totalTrades} - Times Assigned: ${put.stats.totalAssignments} - Total Premium Collected: $${put.stats.totalPremiumCollected.toLocaleString(undefined, { maximumFractionDigits: 0 })} --- ## Key Insights ### Why Options Strategies May Underperform in Bull Markets The 2015-2025 period was an exceptionally strong bull market for SPY: - SPY returned ~${(buyHoldCAGR * 100).toFixed(0)}% CAGR - Multiple +20% years Options premium strategies tend to: 1. **Cap upside** - Covered calls limit gains when stock rallies 2. **Provide downside cushion** - Premium collected offsets some losses 3. **Generate income** - Consistent cash flow even in flat markets ### When Options Strategies Shine - **Flat/sideways markets:** Premium collection without stock movement - **Slightly bullish markets:** Stock appreciation + premium - **High volatility environments:** Higher premiums compensate for risk ### The Synthetic Data Caveat ⚠️ **Important:** These results use **synthetic** option prices generated from: - Historical stock prices - Black-Scholes with estimated IV (historical vol × 1.15) **Real results may differ because:** 1. Actual IV varies significantly (VIX spikes during crashes) 2. Bid-ask spreads on options are wider than assumed 3. Assignment timing differs (American vs European) 4. Dividend effects not fully captured --- ## Methodology ### Option Pricing - Model: Black-Scholes - IV Estimation: 20-day historical vol × 1.15 (typical IV/HV ratio) - Risk-free rate: ${(config.riskFreeRate * 100).toFixed(0)}% ### Strike Selection - Binary search for target delta - ${(config.targetDelta * 100).toFixed(0)}-delta = ~${(config.targetDelta * 100).toFixed(0)}% probability of being ITM at expiration ### Costs Modeled - Slippage: ${(config.optionSlippagePct * 100).toFixed(0)}% of premium - Commission: $${config.commissionPerContract.toFixed(2)} per contract --- ## Recommendations Based on this analysis: 1. **For pure returns:** momentum_plus_multi outperformed all options strategies 2. **For income generation:** Wheel provides consistent premium income 3. **For simplicity:** SPY buy-and-hold remains hard to beat **Consider options strategies if you:** - Need regular income (retirement, living expenses) - Expect flat or moderately bullish markets - Want to reduce volatility (premium cushions drawdowns) - Are comfortable with assignment and stock management --- ## Files Generated - \`options_wheel_2015-2025.json\` - Full wheel backtest data - \`options_covered_call_2015-2025.json\` - Full covered call data - \`options_put_selling_2015-2025.json\` - Full put selling data - \`options_*_trades.csv\` - Complete trade logs `; } main().catch(console.error);
