This is a very common question befalling option buyers since ages. After paying the huge premium and the stock moving in the direction of the option bought if the option buyer sees a loss in options bought they get stressed and start thinking what wrong they did.
This is especially worrisome for novice options traders who just came into the options business. They get worried about seeing a huge decline in option premium if the stock stays in the same place or move slowly in the direction of the option bought. So they ask themselves or their mentors/brokers or keep searching online – why my option declined in price when the stock moved in my option buy direction?
