It is going to additionally contemplate the market situations that favor this technique and potential pitfalls to keep away from.
1. Theta
Theta, representing time decay, performs an important position within the profitability of an extended ATM calendar unfold. This technique depends on the short-term choice expiring nugatory, permitting the dealer to revenue from the premium acquired. As a result of the short-term choice decays at a sooner charge than the long-term choice, the unfold advantages from this distinction. The nearer an choice will get to expiration, the extra quickly its time worth erodes, a phenomenon significantly pronounced within the ultimate weeks and days. For instance, a short-term choice with one week to expiry will lose its time worth a lot faster than a long-term choice with three months to expiry, even when all different components stay fixed.
Understanding theta decay is prime to managing an extended ATM calendar unfold. Merchants usually goal to maximise theta decay by promoting choices with increased theta values. This sometimes entails promoting choices with shorter expirations. Contemplate a situation the place two calendar spreads are constructed with an identical strike costs and underlying property. One unfold makes use of choices expiring in a single month and three months, whereas the opposite makes use of choices expiring in three months and 6 months. The unfold with the one-month and three-month expirations will expertise sooner theta decay on the short-term (one-month) leg, probably resulting in faster income, assuming different components stay steady.
Whereas an extended ATM calendar unfold advantages from time decay, it is essential to keep in mind that different Greeks, particularly vega (volatility), additionally affect the unfold’s worth. Managing a calendar unfold successfully requires a complete understanding of the interaction between all of the Greeks.
