The main advantage of the residual income metric is that it measures excess return earned by a department in absolute terms. A positive residual income means that the department has met the minimum return requirement while a negative residual income means that the department has failed to meet it. Return on investment (ROI) is another metric which measures return in relative terms.
Index funds provide you with a way to invest in the stock market that is completely passive. For example, if you invest money in an index fund that is based on the S&P 500 Index, you will be invested in the general market, without having to concern yourself with choosing investments, rebalancing your portfolio, or knowing when to sell or buy individual companies. All that will be handled by the fund which will base the fund portfolio on the makeup of the underlying index.
Building a website still remains a viable way of earning passive income online despite it being such a competitive venture. Since the internet is saturated with blogs, an entertaining website featuring quizzes or games is a good alternate. Such websites are not too difficult to make and they are easy to promote on social media. They can attract visitors, who will spend a significant amount of time on the site, in droves. Once a site starts recording several thousand visits each day, use the Google AdSense system to start earning revenue through advertising while you relax.
