From Buffett, With Love.(Impactive Capital founders Lauren Taylor Wolfe and Christian Alejandro Asmar)(Contrarian / Money Investing / CFO Network)

The Oracle of Omaha famously detached his investment strategy from his civic pursuits. Lauren Taylor Wolfe and Christian Alejandro Asmar's Impactive Capital borrows from his buy-and-hold value book-but overlays a large amount of sustainability and activism. Wolfe says her biggest disappointment so far with her fledgling hedge fund is that one of its investment wins came so quickly. Wolfe and Asmar, the founders of Impactive Capital, expect every investment they make to be the beginning of a yearslong, hands-on partnership that includes a long-term environmental, social and governance (ESG) initiative to add to a company's bottom line. In an environment in which simply buying an S&P 500 index fund produces impressive returns, the duo are a rarity: deep value investors, outperforming by owning only eight to 12 unglamorous companies at a time.
