![]() These results allow the systematic comparison of the performance of the various routing schemes. For the fourth, most complex, scheme the paper provides performance bounds for the important special case in which the service requirements of high- and low-value callers are the same. For three of these schemes, this paper provides a direct characterization of system performance. These schemes vary in the complexity of their routing algorithms, as well as the sophistication of the telephone and information technology infrastructure they require of the two operations. between the client company and the outsourcer. This paper considers four schemes for routing low-value calls. Typically, they impose service-level constraints on the time each type of customer waits on hold. In some cases, they classify customers as high or low value, serving the former with their in-house operations and routing the latter to an outsourcer. Our empirical tests show the accuracy of the Rule-Base value-at-risk is greatly improved by our adjustment factor in both in-sample and out-of-sample periods.Ĭompanies may choose to outsource parts, but not all, of their call-center operations. The MSCI country and industry indices are used to construct region and industry risk factors. In the empirical tests, we collect 10-day returns of the most frequently pledged stocks from 19 and group them into 10 regions and 10 industries sectors. The combined adjustment factor is derived in closed form. Furthermore, to adjust for the correlation relationship, we adopt a multi-factor framework where the correlations are driven by the regional and industry sectors. Next, in order to correct for the concentration-diversication effect of the portfolio, we propose a variance adjusted concentration measure which generalizes the Herndahl-Hirschman index by weights reflecting the variance of the individual assets. Our calculation first employs a Rule-Based LTV based on the sum of the individuals VaRs, which in turns is individually calibrated to historical volatility-VaR relationship. 1-LTV) is closely related to value-at-risk (VaR) which is very sensitive to model assumptions and complicated to estimate in the non-Gaussian multi-variate case. Key Duration = P – + P + / 2 x 0.This paper implements a simple and transparent procedure for setting loan-to-value (LTV) ratio based on the market risk of the underlying collateralized portfolio. ![]() The key rate duration formula is as follows: There can be a negative or positive key duration. It is divided by the original security price. FormulaĪ key duration formula derives the difference between the price of a security before and after one percent yield changes. In contrast, a fund could be underweighted. This implies that the funds’ duration is long (duration is higher than the benchmark). Instead, fund managers announce that their portfolio is overweight. Investors who deal with mutual fund investments look for the underweight duration. Thus, investors use key duration to decide when to redeem callable bonds. ![]() In callable bonds, the investor can redeem the bond before maturity, but the investor can decide not to do so. It is especially useful for investors who hold a callable bond. Simultaneously, this method is used for comparing fixed-income investments. The key duration is calculated for each maturity level. Regarding United States treasuries, the metric measures yield for 11 bond maturities. Unfortunately, this technique has a massive drawback the trader encounters hedging costs, and the bond’s yield diminishes. They achieve this by implying future derivatives. ![]() Options traders use a technique called key rate duration hedging. They shorten the duration of bonds and aim for a low duration compared to the actual duration of the portfolio. Investors get an idea of the projected profit expected from a particular bond-at various maturity dates. Therefore, every debt securities trader or investor keeps an eye on this metric. The assessment is expressed in 100 basis points, a 1% change in bond yield. Alternatively, the fluctuation is studied about the bond’s yield. It compares bond price fluctuation-occurring after a specific maturity point. Key rate duration is an important metric it is used to assess the sensitivity of bond value. Also, the bond price decreases when there is a potential threat of high-interest rate risk. If the duration increases, the interest rate also increases. Interest rate and duration are directly proportional to each other.There are 11 US treasury maturity levels, and the duration for each level is measured by employing the formula.It can be applied to different debt securities but is most commonly applied to bonds with 100 basis points (1%) increase or decrease in yield. ![]() This metric determines the possible change in bond value from its yield. Key rate duration explains a bond’s price sensitivity. ![]()
