Rolling an Option vs. Accepting Assignment

What a roll actually is

• A roll is two transactions: close the existing option and open a new one with a different strike, expiration, or both.
• Any loss on the original contract is economically real even if the combined order produces a net credit.

Why traders roll

• To extend time
• To move the strike
• To reduce immediate assignment exposure
• To stay with an underlying thesis while changing the position structure

Why assignment can be reasonable

• If ownership was part of the original plan, accepting shares may be cleaner than repeatedly extending an option obligation.
• Assignment can also expose the portfolio to a much larger stock position, so sizing must have been planned in advance.

Avoid automatic decisions

• Neither 'always roll' nor 'never roll' is a complete risk policy.
• The better question is which resulting position you would choose today if you had no existing trade.
