C is correct.Payments, suvin, rethe value of the unrlying whiincreases the value of a Europeput option. Carrying costs rethe value of a Europeput option. increase in the risk-free interest rate mcrease the value of a Europeput option. 中文解析对于欧式看跌期权,因为只能到期行权,他在t时刻的value就是Max[0, X/(1 + r)T -St],如果股票分红增加,分红派息会导致股票的每股净资产减少,所以股价必然下跌。另外由于股票分红时一般会进行除权处理,导致股价降低。那么St就会减小,从而期权的value会增加。另外,从公式可以看出,无风险利率上升,分母变大,会导致期权价值减少。持有成本增加,会导致标的资产价格上升,即St增加,所以会减少看跌期权的价值 如题
