This ETF is designed to mirror the performance of the Shiller Barclays CAPE US Core Sector Index, taking expenses into account. The index's strategy involves identifying and providing exposure to the four most appealing U.S. equity sectors each month. These sectors are strategically chosen based on two primary criteria: being relatively undervalued and demonstrating strong positive price momentum. To facilitate these selections, the index utilizes the Cyclically Adjusted Price Earnings (CAPE) ratio, performing a monthly valuation assessment across nine distinct sectors within the S&P 500 universe to pinpoint those considered relatively undervalued.
