XLSR is a fund of funds that each focus on equities within the individual sector of the S&P 500 Index. The fund employs their own selection model which incorporates macroeconomic, financial and market data to project sector returns. Using these forecasts, the model then allocates the weightings of each equity sector to construct a portfolio that seeks to maximize expected return. Included sectors are communication services, consumer discretionary, consumer staples, energy, financials, healthcare, industrials, materials, real estate, information technology, and utilities. Although XLSR employs a model, the fund is actively managed.
