查询词典 riskless

Secondly, by analyzing basic variables——stochastic cash flow and manager utility function, we gain a proposition (7. 1): If manager is risk averter, then he prefers low risk or riskless and he is satisfied with a basically constant compensation.

资本市场效率越高，企业的股票价格越能反映企业经营情况，因而企业发行股票也就更容易，加上代理人是普遍是避险型的，偏好于股权融资，这样企业的债务比率就会更趋于低负债的资本结构。

Under the assumption that the expected rate μS(t , volatilityσS(t are functions of risk asset S, and stock pricing process respectively driven by a general O-U process and an exponential of a Levy process, we obtain the accurate pricing formulas and put-call parity of European option. In the end, assume that riskless rate is given, we deal with pricing formulas of European option on foreign currency and apply the approach to the pricing of the convertible bond.

利用保险精算方法给出了股票价格遵循广义0一U过程模型的欧式期权的精确定价公式和买权与卖权之间的平价关系以及股票价格过程遵循指数Levy过程的定价模型，最后推导出利率确定情形下外汇期权的定价公式，并且给出了保险精算方法在可转换债券定价中的应用。

4Based on a fact that the price formula of Asian options can be transformed into that of vanilla European option when the time to maturity is less than or equal to the length of average, we skillfully obtain the analytical price formula for the option on the minimum or the maximum of two geometric average prices and generalize it to obtain the price formula of several average prices for the first time. We also apply the method of [121], which approximates the arithmetic average by the geometric average, to the pricing of opitons on the minimum or the maximum of two arithmetic average prices to obtain Its approximated price formula. Numerical results show that the approximated price is relatively accurate when the riskless interest rate is large or the option is in the money and the volatility of two underlying assets are high and its accuracy is a little reduced but still good when the dividends are considered. However, it is hardly affected by the sampling number.

我们基于观察到的一个事实即当离到期时间小于或等于平均期间时亚洲期权的价格可变换成普通的欧式期权的价格，从而巧妙地得到了两个几何平均价格的最小或最大值期权价格的解析公式，通过简单地推广，首次得到了多个几何平均时的价格公式；将[121]用于算术平均亚洲期权的定价方法推广到两个算术平均价格的最小或最大值期权，从而得到它的渐进公式，数值结果表明：渐进价格的准确性在无风险利率较大或期权为实值且两标的资产的波动率较小时较好，抽样的个数对它没有影响，但考虑红利时它稍有下降但仍较好。

The belief that stocks become virtually riskless if you just hold onto them long enough -- popularized a decade ago in books like Jeremy Siegel's 'Stocks for the Long Run' and James Glassman and Kevin Hassett's 'Dow 36,000'-- has been shattered by reality.

那便是，那种以为只要持股时间够长就几乎没风险的信条在事实面前是站不住脚的。这种信条早在10年前就流行于杰里米西格尔的《股市长跑》及詹姆斯格拉斯曼和凯文哈塞特合着的《道指36，000点》(Dow 36，000)等著作中。

Advocating a policy that cannot be guaranteed to work, and that is neither costless nor riskless, is not usually sensible.
