Upside given up above strike5.0%
The premium cushions a decline by 1.79% and no further, below that, you carry the full loss on the shares. Above $105.00 you keep nothing of the rally, which is the real cost of the trade.
Results are arithmetic on the numbers you type. No market data is fetched, and nothing here accounts for early assignment, dividends, taxes, or the bid-ask spread you would actually cross.
