Actively managed ETF targets companies positioned to benefit as power, grid capacity, manufacturing and infrastructure investment accelerate across the U.S. MILWAUKEE, Sept. 16, 2026 /PRNewswire/ -- River1 Asset Management LLC (River1) today announced the launch of the Rebuild America ETF (Cboe BZX: BUIL), an actively managed exchange-traded fund designed to invest in the companies helping meet the growing physical infrastructure buildout of the United States.

This article initiates my coverage of the Trenchless Fund ETF by River1 Asset Management. RVER is actively managed with a 0.65% ER and typically holds only 12-25 stocks. Growth-at-a-reasonable-price is the main objective. RVER's managers select from a wide universe of stocks and have created a portfolio featuring twice the growth of SPY trading at the same valuation. However, RVER's current selections are extremely volatile, evidenced by the portfolio's 1.36 weighted average five-year beta. Their margins are also relatively weak, suggesting quality is not a key focus.

Wednesday saw the launch of the actively managed Trenchless Fund ETF (NYSE Arca: RVER), which invests in a fairly narrow portfolio of U.S.-listed equity securities. The fund has an expense ratio of 0.65%.
