SSXU is a fund-of-funds that seeks to outperform the MSCI ACWI ex USA Index by overweighting and underweighting its exposure to geographic locations relative to the index. The funds advisor uses proprietary models and rankings developed by Ned Davis Research. The models are designed to evaluate fundamental, technical, economic, and behavioral indicators for each region. The indicators include each region's GDP growth, inflation levels, money supply, equity valuations, price-to-earnings multiples, analysts earnings expectations, market trends, and investor sentiment. Based on this information, a risk/reward characteristic for each region is considered. The goal is to select the regions that are perceived to have the highest probability of maximizing total return. Exposure to a particular region will generally range between 0-25%, but not limited. The fund can become concentrated in a particular region. Models are run on a monthly basis, but SSXU is actively managed. Effective April 25, 2025, 'Ned Davis Research' has been removed from the fund's name.
