💡 Key Insights

Profitable Strategy

Total P&L of +$12,950 over 34 trades — the bullish directional bias aligned with XLK's 2025 performance.

⚠️

Win Rate Below 50%

Only 41.2% win rate. A payoff ratio of 2.61x must compensate — check whether winners outsize losers sufficiently.

⚠️

Net Debit Risk Profile

The debit paid is the maximum loss per trade. Multiple losing weeks can erode capital quickly. Directional accuracy is required to generate a profit with this structure.

⚠️

2025 Tech Sector Context

XLK tracks large-cap tech. Macro sensitivity (rates, AI earnings cycles) can cause sharp intraweek reversals that hurt a Mon–Thu hold window even in a broadly bullish year.

⚠️

Model Limitations

All pricing uses real OPRA options bar data from Alpaca (feed=opra). Entry = Monday bar open; Exit = Thursday bar close. No commissions, slippage, pin risk, or early-exercise risk are modelled. Actual results will differ.
