Synthetic Long Stock Calculator
Build stock exposure from a long call + short put — net cost, effective entry and capital saved versus shares.
Formula
By parity, call-minus-put equals a forward on the stock — same dollar-for-dollar exposure, fraction of the capital. The 'free leverage' is priced: the net debit embeds the financing rate, and the short put can be assigned early around dividends.
