I'm comparing these two strategies with different DTE on a covered short strangle, where even the put is cash-secured.
1st strategy: "shorter DTE"
put: strike 50k, expiration date 27-Jun-25, delta -3, premium $600
call: strike 200k, expiration date 27-Jun-25, delta 6, premium $850
2nd strategy: "longer DTE"
put: strike 50k, expiration date 26-Dec-25, delta -6, premium $1,900
call: strike 200k, expiration date 26-Dec-25, delta 21, premium $5100
rationale: I'd be happy to increase my bag on the underlying at 50k and happy to give it away at 200k.
There are no expirations that perfectly double the DTE, but does not matter that much.
Other things being equal, with these premiums, choosing the longer DTE strategy seems better than repeating the shorter DTE strategy two/three times. Am I missing something? Would be great to know I am wrong, but through a serious explanation and not the usual mantra *do-not-exceed-60-days-DTE-because-theta-decay-is-greater-the-closest-to-expiration-ooom*
