💡 Key Insights

Profitable Strategy

Total P&L of +$5,336 over 16 weeks demonstrates consistent edge for the bear call setup on MU.

Win Rate Above 50%

75.0% win rate over 16 trades — statistically meaningful sample size.

Positive Sharpe Ratio

Annualised Sharpe of 2.04 indicates reasonable risk-adjusted returns.

⚠️

2022 Bear Market Context

Jan–Oct 2022 was a significant equity drawdown period. MU fell ~50% over this window, which can generate both wins (short bias aligned with trend) and large losses on counter-trend weeks.

⚠️

Model Limitations

All pricing uses Black-Scholes (European) with 20-day trailing historical vol. No commissions, slippage, pin risk, or early-exercise risk are modelled. Actual results will differ.
