It can additionally take into account the market situations that favor this technique and potential pitfalls to keep away from.
1. Theta
Theta, representing time decay, performs a vital position within the profitability of an extended ATM calendar unfold. This technique depends on the short-term possibility expiring nugatory, permitting the dealer to revenue from the premium acquired. As a result of the short-term possibility decays at a quicker price than the long-term possibility, the unfold advantages from this distinction. The nearer an possibility will get to expiration, the extra quickly its time worth erodes, a phenomenon significantly pronounced within the remaining weeks and days. For instance, a short-term possibility with one week to expiry will lose its time worth a lot faster than a long-term possibility with three months to expiry, even when all different elements stay fixed.
Understanding theta decay is key 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. Take into account a state of affairs the place two calendar spreads are constructed with an identical strike costs and underlying belongings. 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 quicker theta decay on the short-term (one-month) leg, probably resulting in faster earnings, assuming different elements stay secure.
Whereas an extended ATM calendar unfold advantages from time decay, it is essential to do not forget 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.
