The one-standard-deviation move is calculated by multiplying the asset price by the daily volatility percentage.

Calculation:

• Asset price = $80
• Daily volatility = 2% = 0.02
• One-standard-deviation move = $80 × 0.02 = $1.6

This represents the expected price movement (up or down) that would occur approximately 68% of the time under normal distribution assumptions for a one-day period.
