SEIM actively manages a portfolio of equity and equity-related securities, issued by large-cap companies in the US that display a relatively strong recent performance or momentum. The fund provides an efficient way to focus on momentum investing, a trend-following investment strategy, wherein it acquires stocks or other securities having recent high returns and improvements in their price, earnings or other relevant fundamentals. The selection process involves 1) a quantitative model and rules-based screening process, which evaluates potential constituents based on several factors such as historical share price performance, earnings and profitability trends, unanticipated financial results, and changes to analyst outlooks, and 2) an optimization process to ensure high primary exposure to superior momentum stocks. SEIM launched as a part of SEIs first equity ETF offering, the Factor ETF suite.
