I work at a small software company that started to work on economy and finance related projects. We are writing different python notebooks to play with ideas of economy and finance that we like to investigate. We are studying some of Ray Dalio books and interviews. In this case we focused on a video where he explained why diversification is important.
The benefits of diversification are generally well known: reduced risk through exposure to different sources of income. The insight Dalio brings to the forefront, is that the construction of a diversified portfolio through a combination of uncorrelated return streams, significantly decreases our overall risk, raising in turn our return / risk ratio.
