SIXL actively selects approximately 240 equally-weighted all-cap US equities from the S&P large-, mid- and small-cap indices that exhibit the lowest beta. Portfolio construction begins by ranking securities based on profitability, growth and debt service coverage. Stocks scoring poorly in this composite measure are removed from the investable universe. Remaining securities are ranked according to their relative market risk/volatility, beta. Securities with the lowest measured beta forms the final portfolio. The fund may also invest in REITs. On Nov. 16, 2021 ETC took over distribution of the fund.
