The Invesco Building & Construction ETF, identified by the symbol PKB, is structured to align its investments with the performance of the Dynamic Building & Construction Intellidex Index. Typically, the Fund allocates a minimum of 90% of its total capital to the securities that constitute this benchmark. To select its constituents, the Index rigorously assesses potential companies based on a range of investment merit factors. These include a company's stock price trajectory, the expansion of its earnings, overall corporate quality, strategic management decisions, and valuation metrics. The Index's portfolio is comprised of shares from 30 American enterprises operating within the building and construction sector. These included firms are predominantly engaged in providing construction and associated engineering services. Their work spans a broad spectrum, from the development and renovation of residential, commercial, and industrial properties to undertaking significant infrastructure endeavors such as highways, tunnels, bridges, dams, power networks, and airfields. To maintain its relevance and focus, both the Fund and the Index undergo rebalancing and reconstitution processes on a quarterly basis, specifically in February, May, August, and November.
