Many investors have strong opinions that don’t involve their views on interest rates and stock prices. This might include support for a clean environment or concern for the poor and the disadvantaged–just to mention a few well-known causes. Increasingly, these investors want their holdings to reflect their social, ethical or religious values. They wish to avoid companies that profit from activities they oppose, and support companies that behave in ways they consider appropriate or responsible. At the same time, however, most investors still want or need to earn a reasonable return on their portfolios.
