Partners Healthcare Case Aanlysis Essay

Partners Healthc be had established several financial resources pools, such as the short-run pool (s.t.p.) and the LTP, so that they so-and-so satisfy assorted postulate of the several infirmarys in the network. In more detail, the s.t.p. was directed with very high-quality, short- precondition fixed-income financial instruments. The average maturity of these instruments is about iodine to two years. STP is always treated as the fortune- drop by the wayside part of the hospitals holdings. On the some other hand, the LTP is thought as the findy part of holdings. It consists of different forms of equity and a smaller fixed-income part.In order to diversify the risks of the LTP, the Partners investment funds committee introduced a bleak type of summations, unfeigned assets, into the original LTP during the past years. Both of the assets slaying turned to be excellent during 2004. As a result, the Investment Committee was considering expanding the real-asset segment of the LTP. Michael Manning, the deputy treasurer of Partners Healthcare System, was asked to recommend the size and the report for the real-asset portfolio contributed to the $2.4 billion long-term pool (LTP) in the Partners. Facts and AnalysisDue to the fact that different Partners Healthcare hospitals might have different acceptable risk levels for their investment portfolio then the most reasonable solution would be to invest both in risk-free STP and risky LTP. By choosing different mixes to each one(prenominal) hospital could achieve their acceptable risk level.Since the STP has a nearly fixed rate of consecrate considered to be risk free for each hospitals own portfolio, the variation from LTP would ultimately moderate the risk and return level of individual portfolio. Using long-term historical data, Manning and his staff measured average annual returns, volatilities, and co cost-effective of correlations for each of the asset classes (exhibit 3). Since real assets belon g to LTP, there is no direct impact on the STP returns from investing in this category. Given the current mix of Domestic Equities (55%), unconnected Equities (30%) and LT Bonds (15%) and our evaluate return for each category (exhibit 3), the expected return of the LTP is calculated from the following formula e.g. E(Rp)= 0.55(0.1294)+0.30(0.1242)+0.15(0.054) = 10.8%In order to recall the optimal portfolio allocation, the free radical needs to find the portfolio structured with lowest risk under a given return. This basin be achieved by applying Mean-Variance Theory and Markowitz model find the effectual frontier, which fruits the most optimal portfolio under given returns. It give the axe be expressed in mathematical terms and solved by quadratic equation programming. Appendix AIn this case, the Partners Treasury Department has computed all the portfolios for minimal level of risk with different types of assets, more specifically, adding Real Estate Investment Trusts (REIT s), Commodities or both, from an undefined approach. Since the results are identical as calculated from Mean-Variance Theory, they should be the optimal portfolios for each target level of return. Therefore a chart with efficient frontier, which represents the optimal portfolios with different assets, is constructed based on Exhibit 5 to 8 for comparison. Appendix B Technically, any portfolio on the efficient frontier is an optimized portfolio and is indifferent from each other in terms of risk/return trade off.From the put on the line VS Return graph, we can see that for any given return, the portfolio with both REITs and commodities would yield the lowest risk. Also, the portfolio with just now commodities would outperform the portfolio with only REITs. For instance, if we invest in both REITs and Commodities, in order to obtain a return of 10%, the new proportion of the LTP will be portfolio 4 with approximately US virtue 14.3%, Foreign Equity 27.5%, Bonds 22.2%, REITs 13.8%, and Commodities 22.3%. It produces the lowest risk of 8.49%, comparing to original portfolio of 9.94%, REITs only portfolio of 9.69% and Commodities only portfolio of 8.49%. This is the basic concept of diversification, which means that the more assets with less correlation are introduced to the portfolio the less risky the portfolio will be for any accomplishable rate of return. 1For the overall portfolio, each hospital can allocate amid the STP and the LTP. In fact, they can always construct the most efficient portfolio for their acceptable risk level with conclave of LTP, which holds the risky assets, and STP, which holds the risk-free asset according to The One-Fund Theorem. 2 For example, if the shareholders want a total return of X, with a 3.2% return of STP and a 10% return of LTP, the proportion of STP and LTP can be obtained through X= w(0.032) + (1-w)(0.10)And it is guaranteed to be the optimal portfolio.Even though Mean-Variance theory can allocate the most optimal po rtfolio, there are several flaws with its assumptions. First of all, it assumes that assets returns are normally distributed. However, often times, its detect that asset returns are more like to be fat-tailed distribution, 3 instead of having melt off tails like normal distribution. Second of all, it assumes there is a eternal correlation between different assets.However, under certain conditions, for example, severe financial crisis like 2008, all assets tend to be positively correlated with diminish rate of return. Depending on the total time period used for historical data, it can place an impact on the long term correlation. deviation from the assumptions, the time period of data can also affect each variable. In this case, the client uses data started from 1970 for the new asset classes, which might non be as representative as using long term historical data from 1926 as they did with the US equities and US long-term bonds. This can have some impacts on the returns, stand ard deviations, and correlations depending on the movement of assets from 1926 to 1970. testimonialBy comparing the data in the table of Exhibit 5a with the numeral results shown in Exhibit 6 and Exhibit 7, as well as the efficient frontier constructed, we can derive the conclusion that with the same expected returns, the most optimal portfolio is to add both REITs and commodities. In other words, we can control the risk of LTP by expanding the portion of real assets. If only one asset is allowed to be added to the real asset category, its more efficient to add the commodities than the REITs based on the position of the efficient frontier. Therefore, with a combination of risk free STP and the improved LTP, each individual hospital is able to construct the most optimized portfolio under any given risk level.
