The Greeks measure how an option's value reacts: delta to the underlying price, gamma to delta itself, vega to volatility, theta to the passage of time. Traders hedge by neutralizing them. Educational tool, not financial advice.

Governing equation

Δ = N (d_{1}), d_{1} = \frac{ln ( 100/100 ) + ( 0.04 + 0.2 5 ^{2} /2 ) 0.5}{0.25 0.5} = 0.202 \Rightarrow Δ = 0.580

Reading this result: Near the money, gamma and vega peak: the option is most sensitive to both price swings and changes in volatility (vega 0.28 per 1% vol).
