The option is quoted at $.76, so one contract costs 100 × $.76 = $76. Your 10 contracts total $760. You now have the right to sell 1,000 shares of CSCO for $25 per share. If the stock is currently selling for $21.50 per share, then this is most definitely good news. You can buy 1,000 shares at $21.50 and sell them for $25. Your puts are worth $25 − 21.50 = $3.50 per share, or $3.50 × 1,000 = $3,500 in all. Because you paid $760, your net profit is $3,500 −760 = $2,740.
