- Main Sector Rotation ETF (SECT) is an actively managed exchange-traded fund that employs a dynamic sector rotation strategy to outperform the S&P 500 Index in rising markets while seeking to limit losses during periods of market decline; it invests primarily as a fund-of-funds in U.S. sector-based equity exchange-traded funds across sectors such as technology, financials, healthcare, consumer discretionary, industrials, energy, utilities, materials, communication services, real estate, and consumer staples. The fund optimizes sector allocation by analyzing sectors, industries, and sub-industries to identify those that appear undervalued and positioned to benefit from financial market catalysts, selling holdings when target prices are achieved or undervaluation dissipates. Managed by Main Management Fund Advisors, LLC, SECT holds approximately 10 positions at any given time, maintains flexibility across market capitalizations, and may concentrate in one or more sectors based on the adviser's assessment.
Launched on September 5, 2017, and listed on the NYSE Arca exchange, SECT is sponsored and managed by Main Management, LLC, an investment management firm founded in 2002 and headquartered in San Francisco, California. Main Management, a pioneer in ETF portfolios, oversees approximately $3.27 billion in assets across four ETFs, including SECT (with assets exceeding $2.4 billion), Main Thematic Innovation ETF (TMAT), Main International ETF (INTL), and Main BuyWrite ETF (BUYW); the firm targets institutional and high-net-worth clients through customized model partnerships, high-touch service, and strategies emphasizing income generation, volatility management, and thematic innovation. SECT operates within the large blend category, serving investors seeking broad U.S. equity exposure via tactical sector shifts without geographic restrictions beyond its core U.S. sector focus.
In recent developments, Main Management lowered the net expense ratio for its Main BuyWrite ETF (BUYW) to enhance competitiveness, coinciding with BUYW marking its 20-year milestone as a pioneering covered call overlay strategy among the first 15 in Morningstar's Derivative Income category. The firm appointed Rusty Vanneman, a veteran investment executive with over 35 years of experience, as Chairman of its Advisory Board to guide future growth while upholding "Client First, Exceptional Service" principles; Vanneman, a long-time collaborator and conference speaker, aligns with Main's team-based process and personal investments in its strategies. These enhancements reflect Main Management's ongoing commitment to refining offerings and expanding advisory capabilities amid a robust performance environment, with SECT delivering year-to-date returns around 17.55% and one-year gains near 23.8% as of late 2025.
