Assignment 1_Solution
5. (5-24) A stock is expected to pay a dividend of $1 per share in two months and in five months. The stock price is $50, and the risk-free rate of interest is 8% per annum with continuous compounding for all maturities. An investor has just taken a short position in a six-month forward contract on the stock. a) What are the forward price and the initial value of the forward contract? b) Three months later, the price of the stock is $48 and the risk-free rate of interest is still 8% per annum. What are the forward price and the value of the short position in the forward contract? Solution: a) The present value, I, of the income from the security is given by: I = 1× e −0.08×2/12 + 1× e −0.08×5/12 = 1.9540. From equation (2.3) the forward price, F0, is given by: F0 = (50 − 1.9540)e0.08×6/12 = 50.01. The initial value of the forward contract is (by design) zero. The fact that the forward price is very close to the spot price should come as no surprise. When the compounding frequency is ignored the dividend yield on the stock equals the riskfree rate of interest. b) In three months: I= 1× e −0.08×2/12 = 0.9868. The delivery price, K, is 50.01. From equation (2.9) the value of the short forward contract, f, is given by: f = −(48 − 0.9868 − 50.01e −0.08×3/12 ) = 2.01. And the forward price is (48 − 0.9868)e0.08×3/12 = 47.96. 6. (5-27) A trader owns gold as part of a long-term investment portfolio. The trader can buy gold for $550 per ounce and sell gold for $549 per ounce. The trader can borrow funds at 6% per year and invest funds at 5.5% per year. (Both interest rates are expressed with simple annual compounding.) For what range of one-year forward prices of gold does the trader have on arbitrage opportunities? Assume there is no bid-offer spread for forward prices.

这些系统和网站都依靠着数据库的支持，才能正常运行。
最近阿里巴巴的上市引起了许多人的关注，而阿里巴巴集团旗下的淘宝网也已经成为了人们日常生活中必不可少的东西。
而淘宝网能够正常运行，少不了数据库的支持。
我们要想在淘宝网上买东西，首先必须要有一个淘宝账户，所以，我们需要进行注册，输入自己的用户名、密码等相应资料，而我们的账户信息就存储在淘宝网的后台数据库中，因为有了数据库的支持，我们可以看到自己的交易记录、收藏的商品、物流的信息等等。
商家需要将自己的商品信息进行存储，商品的价格、库存、颜色、尺寸等等信息都会存储到数据库里，因为数据库，我们才能浏览到商品，获知商品的各种信息。
还有商家的信息，如网店的创建时间、网店的评分、客服人员等等也会存储到数据库里。
如果我们选择网上付款，那各大银行的网银系统也需要有自己的数据库来存储客户的信息。
我简单的将数据库中存储的数据罗列下来：12345。
