问题如下：
Stock A and Stock B are both traded at $50 per share in the same market. Stock A is a growth stock with no dividend payment plans, while Stock B is a value stock and plans to pay dividend in next month. Assuming all else equal, the three-months forward price of:
选项：
A.
Stock A is expected to be higher than Stock B
B.
Stock A is expected to be lower than Stock B
C.
Stock A cannot be determined compared to Stock B
解释：
A is correct.
The forward transaction will forgo the benefits and avoid cost. Dividend payment is benefit to stock holders. Therefore, the forward price is the spot price compounded at the risk-free rate over the life of the contract minus the future value of those benefits. Stock A, which has no dividend payment plan, will have a higher forward price than Stock B.
中文解析：
现货持有方是可以获得红利的，而远期合约的long方无法获得，因而远期合约的价格应当在现货价格基础上扣除红利的影响。这道题A股票没有红利，B股票有红利，两者价格相等，但B需要扣除红利影响，所以A股票为标的资产的期货价格会更高。
就是a是 最原始的那个公式
B是so-pvdividend这个公式。。。
但是不看公式，我还是有点理解不了呢。
我记得老师上课讲过，持有现货cost越高，远期合约就贵。那这个B的成本不就高于A吗？他有分红。。。虽然拿不到。。。
