DEEP holds deeply undervalued names from the smallest 75% of US stocks, including micro-cap, that are fundamentally strong. The underlying index uses its valuation metric called The Acquirers Multiple. This model evaluates constituents in multiple stages to arrive at a very narrow selection of value stocks. Stocks are first examined and ranked individually based on their assets, earnings, and cash flows. Potential components are further screened for fraud, earnings manipulation, and financial distress, with margin of safety being considered in the examination. Finally, each remaining component is carefully examined for forensic accounting review of their financial statements. The top 100 stocks that pass each stage form the portfolio, with each name receiving an equal weight of 1%. Rebalancing and reconstitution occur quarterly. Before October 26, 2020, DEEP was focused on large-caps only. Following December 23, 2024, DEEP removed Roundhill from its fund name.
