The disadvantage of this position is a limited life-span and, since it is not long stock, the owner of this combo will not benefit by receiving the dividend if there is one. If AAPL is trading $525 and I buy the December 525 calls for $25 and sell the December 525 puts for $25, I own this stock for $525, but would without the capital outlay of $52,500.
