As many as you like! We recommend you select at least 5 topics. If you choose fewer impact topics, you may see more "stability positions" in your strategy. Stability positions are companies that do not necessarily match your impact topics, but are added to help diversify and minimize the risk in your portfolio.
Don’t worry about financial performance when you select your impact topics. With every choice you make, the Yova Engine makes sure your portfolio is financially sound and designed to grow with the economy in the long-term.
