If you're looking to make socially responsible investments, you'll want to avoid investing your funds in companies that produce addictive substances (like tobacco and alcohol) or businesses participating in animal exploitation, gambling, and the distribution of weapons. Instead, you'll want to find companies that align themselves with environmental causes, sustainability, social justice, or similar movements. For example, the ClearBridge Sustainability Fund is one of the top socially responsible investing funds available. Its top holdings are Costco, Apple, Microsoft, and Alphabet.
