It should come as no surprise then that investors have carved out a niche strategy within the market known as "socially responsible investing", in order to align their political and ethical goals with their economic aspirations.

What Is A Socially Responsible Investment?
Socially responsible investments will differ for each investor according to his or her convictions. One investor may feel there is nothing wrong with a particular company's line of work or business practices, while another may consider the company entirely unethical. While there is no universal set of characteristics that define a socially responsible stock, there are certain themes that tend to be commonly associated with socially responsible investing.

First off, socially responsible investors typically prefer to avoid making investments in companies that engage in the production or sale of alcoholic beverages, tobacco products, gambling or sports betting activities, adult entertainment, and tools of warfare or violence (guns, bullets, bombs, etc.).
As well, socially responsible investors typically seek to invest in companies that possess a healthy amount of environmental responsibility and contribute to environmental sustainability, renewable energy and clean technology.

Social Responsibility, IndexedWhile it is of course a subjective decision to label any one company socially responsible or not, the Dow Jones Sustainability United States Index provides investors who are interested in making socially responsible investments an easy way to produce a shortlist of companies that are generally regarded as among the most socially responsible public companies. The index is reviewed quarterly, in order to stay up to date with the changing business environment.

This can be particularly useful for individual investors, since researching all the aspects of a large company's operations and business practices in order to rule out the existence of any socially irresponsible activity can be quite time-consuming. In other words, limiting your investment selections to companies listed on an index such as this will likely not create an investment portfolio that perfectly matches all of your political and ethical concerns, but it will ensure that your investment capital goes into companies that are regarded as socially responsible on average compared to most companies.
