Delta Spread

An options trading strategy where the trader initially establishes a delta neutral position. The trader creates this delta neutral position by simultaneously buying and selling options in proportion to the neutral ratio. Using a delta spread, a trader usually expects to make a small profit if the underlying security does not change widely in price. However, larger gains or losses are possible if the underlying security's prices changes significantly in either direction. The most commonly discussed delta spread is a calendar spread. The calendar spread involves constructing a delta neutral position using options with different expiration dates. In the simplest example, a trader will simultaneously sell near-month call options and buy call options with a later expiration in proportion to their neutral ratio. Since the position is delta neutral, the trader should not experience gains or losses from small prices moves in the underlying security. Rather, the trader expects the price to remain unchanged, and as the near month calls lose time value and expire, the trader can sell the call options with longer expiration dates and hopefully net a profit.

Periodic Payment Plan

A type of investment plan, often sold to military personnel, that allows an investor to accumulate shares of a mutual fund indirectly by contributing a small, fixed sum over a period of usually 10, 15, or 25 years. In exchange for these payments, the investor owns an interest in a plan trust, which invests in a mutual fund. The plan trust's sponsor makes money by charging a "creation and sales charge", also known as a "front-end load", to investors. This sales charge is as high as 50% of the first 12 months' worth of payments, making periodic payment plans a potentially expensive investment option, especially for investors who do not remain invested for the full length of the plan. Most periodic payment plans also have an annual fee and small monthly custodial fees. As a result of these fees, investors may be able to get a better deal by purchasing mutual fund shares directly. While the low required monthly contribution may be a selling point of a periodic payment plan, some brokerage companies, whose fees may be lower than that of a periodic payment plan, will allow investors to make small monthly investments and avoid large minimum investments if they establish automatic deposits. Also known as a "contractual plan" or "systematic investment plan".

招聘测试

什么是招聘测试　　在企业员工招聘过程中、招聘测试是重要的一环。　　招聘测试是指在招聘过程中，运用各种科学方法和经验方法对应聘者加以客观鉴定的各种方法的总称。人与人之间是存在差异的，这种差异可以通过各种方法加以区别，这为招聘测试奠定了基础。招聘测试的种类　　企业员工招聘测试中种类很多，目前我国企业比较适用的有以下几种：　　1、心理测试　　心理测试是指通过一系列的心理学方法来测量被试者的智力水平和个性方面差异的一种科学方法。通过心理测试可以了解一个人所具有的潜在能力，了解一个人是否符合该企业某一岗位的需要。　　2、知识考试　　知识考试是指主要通过纸笔测验的形式，对被试者的知识广度、知识深度和知识结构了解的一种方法。　　3、情景模拟　　情景模拟是指根据被试者可能担任的职务，编制一套与该职务实际情况相似的测试项目，将被试者安排在模拟的、逼真的工作环境中。要求被试者处理可能遇见的各种问题，用多种方法来测评其心理素质、潜在能力的一系列方法。　　4、面试　　面试是指一类要求被试者用口头语言来回答主试者提问，以便了解被试者心理素质和潜在能力的测评方法。招聘测试的特点　　1、标准化　　标准化指的是进行一项测验的条件和程序上的连贯性或一致性。每一项测验必须有自身的标准程序，而每次进行测验时必须准确地遵循这些程序。　　2、常模　　为了阐明心理测验的结果，必须有一种理论上可与之比较的尺度，以便把一个人的绩效与另一个相仿的人比较，这是运用测验常模来完成的。常模是在性质上与受测验的工作申请人相同的一大批人所得的分数的分布。假如某人在某项常模为80±10的测验中得分为82，则可判断该人成绩为一般水平。　　某些广泛采用的心理测验有各种常模分别用于不同年龄、性别和教育水平。恰当的常模在选拔中起重要作用。　　3、客观性　　客观性指记录测验得分不受记分者主观判断或偏见左右，即任何人来记录测验分数都能得到同样的结果。为了对工作申请人作出公正的评价和在他们之间进行公正的比较，显然客观性测验是较为理想的。　　4、可靠性　　可靠性指对一项测验所产生的反应的一致性。在一项测验可以公开推广之前，必须确切地指出该测验的可靠程度。在选用一种作为选拔用人的测验时，理想的可靠性系数应该大于0.8。　　5、有效性　　有效性就是指实际地测量所要测量的东西，判断有效性的一个方法是把测量的得分与今后的工作绩效联系起来。招聘测试的意义　　招聘测试，有时简称测试，在员工招聘中具有重要意义。　　1、挑选合格的员工，应聘者的各种条件，不一定符合招聘者的各种要求。挑选合格的员工对于建立企业文化，提高生产率，发展企业均有重要的推动作用。只有通过测试才能被挑选为合格的员工。　　2、让适当的人担任适当的工作，许多应聘者来应聘多个岗位时，有时会出现“某人适合从事甲岗位而不适合从事乙岗位”的现象，只有通过测试才能了解谁担任哪个岗位最合适。　　3、体现公平竞争原则。当应聘者多于招聘名额时，测试可以让最合适的人选脱颖而出，落选者也能了解自己的不足之处，相对比较心平气和地接受落选的事实。

At this time, coins were struck in cêntimos and lower denomination dobras (one, two and five dobra coins ).
