Alpha Factor in Portfolio Construction When Risk and Factors Are Misaligned

The Star Mine Combined Alpha Model (SCAM) mixes together all existing Star Mine alpha models in a static, optimal, mixed-range configuration.alpha model The weights assigned to the different models vary regionally. The Star Mine CAM takes advantage of the localized strength of some areas, including Japan and the Low Tropic Area, while in the other regions, such as West Africa and Central Asia, the terrain is more spread out and the terrain model is more balanced. In this manner, the SCAM manages to provide a good match between the actual terrain and the expected tactical situation for each area.

The Star Mine CAM and the RCP are both based on historical performance metrics.alpha model alpha model Therefore, it is important to check both the historical performance of the models against the current portfolio. The RCP is primarily used for risk management with fixed probabilities. The CAM is primarily used for outperformance optimization with time-dependent volatility. Both methods can be mixed with the others to provide an accurate measure of the portfolio's outperformance against the index.

Both the alpha models allow one to calculate the portfolio's outperformance against the index using data from the past. However, it is important to note that historical data do not represent future returns because they are for a known span only. For example, if a stock has been increasing in value for three years, one can calculate the value of stocks from the past using the latest period data. Likewise, if a stock has been decreasing over the same period, one needs to make a calculation using the earlier period data. This is the reason why historical data are most useful for assessing long-term trends.

On the other hand, the beta and the Cambodia models allow portfolio managers to make better decisions when it comes to choosing which stocks to buy or sell. These two models have their own advantages and disadvantages. The beta model tries to anticipate the behavior of the market based on statistical data. It attempts to forecast which stocks will gain or lose value based on present market conditions. Meanwhile, the Cambodia model considers recent history in analyzing the behavior of prices. It attempts to evaluate the effect of external economic factors such as interest rates, unemployment rate and consumer spending habits on the prices of a particular security.

One important advantage of the beta Alpha Model is its ability to accommodate information that may be difficult to obtain using the more conventional methods. For example, data on company-specific productivity growth rates and economic growth rates are difficult to obtain. The beta Alpha can capture these relevant data points by taking into account historical factors that are difficult to obtain in the case of non-cyclical companies. Similarly, the beta Alpha can accommodate information on various economic variables that are sensitive to economic cycles such as interest rates. As the book rightly shows, the Cambodia's long term economic growth prospects depend a lot on external factors.

On the other hand, the beta Alpha can only perform well if it has access to accurate economic indicators that are consistent over time. These include the U.S. economy, European economies, Japanese economic growth, Indian economy, commodity markets and many others. A drawback of the beta Alpha model is that it only considers the past behavior of securities. It cannot make any inferences regarding the future stock market behavior.
