This is a good learning experience for the newbie option players. Looking at the CYMI Aug 25 Puts, the option itself should be negative for the day considering the underlying stock is trading up .50 but because there is so much buying interest and volume today, especially compared to Open Interest (OI), the option is up .80 to 1.75. As long as there is buying pressure on any option like this, it doesn't matter how the underlying is trading.
