Stock ABC is currently priced at $50. Consider two 6-month options on stock ABC: Option 1: $60-strike call (priced at 30% implied vol). Price works out to $1.27. Delta = +0.23 Option 2: $40-strike put (priced at 40% implied vol). Price works out to $1.56. Delta = -0.18 (Prices and deltas have been calculated via the Black-Scholes model, assuming q=0% and r=0%.) Suppose a trader holds: 100 units of Option 1 and 200 units of Option 2.
