Alternative Completion Index (IBBACI)
The Ibbotson Alternative Completion Index, published under the symbol "IBBACI," tracks the investment performance of a group of asset classes and investment strategies that are expected to have a low correlation, or different performance characteristics, to traditional stock and bond asset classes. It is rebalanced quarterly on the first business day of the quarter.
Index Methodology and DefinitionThe Ibbotson Alternative Completion Index (IBBACI) seeks to track the investment performance of a group of asset classes and investment strategies that are expected to have a low correlation, or different performance characteristics, to traditional stock and bond asset classes. These “alternative” asset classes and investment strategies are combined into the Index using a five-step construction process. First, asset class and investment strategy performance is examined using a combination of historical data, current market information and additional analysis. Expected returns, standard deviations and correlations are developed for each alternative investment option. Next, the asset class model for the Index is created by determining the optimal weight for each alternative asset class as part of an overall investment portfolio. A variety of techniques are used in this step including resampled optimization and sensitivity analysis to ensure the stability of the asset allocation recommendations under a variety of market scenarios. In the next step, the Index constituents are selected from the available investment options based on a number of qualitative and quantitative investment factors. Next, the Index is constructed using approximately twelve to fifteen alternative ETFs to implement the target asset class model. In the final step, the Index is monitored and reviewed regularly to ensure that it stays in line with its strategic asset allocation target. The Index will be rebalanced quarterly on the 1st business day of the quarter.
