ECACX Investment Objective and Strategy
MFS Conservative Allocation Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Mfs Series Trust X.
Investment objective
The funds investment objective is to seek a high level of total return consistent with a conservative level of risk relative to the other MFS Asset Allocation Funds. (The MFS Asset Allocation Funds currently are MFS Conservative Allocation Fund, MFS Moderate Allocation Fund, MFS Growth Allocation Fund, and MFS Aggressive Growth Allocation Fund.)
Principal investment strategy
The fund is designed to provide diversification among different asset classes by investing its assets in other mutual funds advised by MFS (Massachusetts Financial Services Company, the funds investment adviser), referred to as underlying funds. The underlying funds are selected following a two stage asset allocation process. The first stage is a strategic asset allocation to determine the percentage of the funds assets invested in the general asset classes of (1) Bond Funds, (2) International Stock Funds, and (3) U.S. Stock Funds, as well as (4) Specialty Funds (underlying funds that have less traditional investment strategies that MFS believes provide diversification benefits when added to a portfolio consisting of stock and bond funds) based on the risk/return potential of the different asset classes and the risk profile of the fund.
The second stage involves the actual selection of underlying funds to represent the asset classes based on underlying fund classifications, historical risk, performance, and other factors. Within the stock fund allocations, MFS seeks to diversify by geography (by including domestic and international underlying funds), in terms of market capitalization (by including large, mid, and small capitalization underlying funds), and by style (by including both growth and value underlying funds). Within the bond fund allocation, MFS includes underlying funds with varying degrees of interest rate and credit exposure. MFS normally invests the underlying funds assets across different industries, sectors, countries, and regions, but MFS may invest a significant percentage of the underlying funds assets in issuers in a single industry, sector, country, or region.
