Calendar & diagonal spreads
How do I adjust a diagonal spread when the short front-month strike is deeply breached?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
When the short front-month strike is deeply breached, traders typically roll the short leg to a further strike or later date, convert the position by closing both legs, or accept the position as effectively a directional diagonal.
How it works
Because a deep breach erodes the time-decay edge and increases directional exposure, adjustments generally aim to either reduce further loss or reposition the trade to reflect the now-directional reality.
An example
If the stock rallies past the short 100 strike to 110, a trader might roll the short call up to a 110 strike in a later expiration to reduce the diagonal's directional risk.
Risk & limitations
Rolling a breached leg can lock in a loss or extend risk rather than resolve it, and repeated rolling increases transaction costs without guaranteeing eventual profitability.
