标的涨期权为什么不涨？

Group 1 - The phenomenon of call options not increasing in price despite the underlying asset's price rising can be attributed to several key factors [3][4][6] - Changes in the underlying asset's price directly affect the price of call options, and if the asset's price does not rise or falls, the call option price may not increase [3][6] - Volatility is a critical factor; a decrease in volatility can lead to a situation where the price of call options does not rise even if the underlying asset's price increases [3][6][7] Group 2 - Time decay is a significant reason for the lack of increase in call option prices; as the expiration date approaches, the time value of options diminishes, potentially offsetting any gains from the underlying asset's price increase [6][7] - Market demand for options can also influence their prices; a decrease in demand for call options can result in stagnant or declining prices despite favorable movements in the underlying asset [3][4] - Macroeconomic conditions and policy changes can impact the pricing of call options, as tighter monetary or fiscal policies may lower overall market risk appetite, affecting option prices [3][4]
