PeakShares Sector Rotation ETF (PSTR) is an actively managed exchange-traded fund that seeks to outperform the S&P 500 Index through a proprietary sector rotation strategy based on economic cycle analysis. The fund invests primarily in other ETFs that provide exposure to specific U.S. equity sectors, including technology, healthcare, consumer discretionary, financials, industrials, and others; it dynamically allocates assets among these sector ETFs to capitalize on macroeconomic trends such as expansion, peak, contraction, and trough phases. PSTR employs a rules-based model incorporating leading economic indicators, market breadth signals, and relative sector strength metrics to guide monthly rebalancing decisions. Launched in 2022, the ETF is issued by PeakShares Trust and managed by Exchange Traded Concepts, LLC, with headquarters in Austin, Texas; it primarily targets U.S. institutional and retail investors seeking tactical equity exposure. In 2024, the fund expanded its strategy to incorporate enhanced risk management overlays amid heightened market volatility, including tighter stop-loss parameters and increased emphasis on defensive sectors during contraction signals.
