The risk scale proposed by us is a simplified way of grading different portfolios according to inherent risk associated with the investments made in the portfolio. The risk scale is graded from Zero to Ten for convenience. We have placed the portfolios of our various schemes at different points on this risk scale to communicate the relative risks, as we perceive it.
Risk essentially means uncertainty of outcome or the possibility of an adverse outcome.
If you are walking on the road, risk means a running bus may hit you. Such a risk does not exist if you are walking down a garden path. But on a garden path there is no destination, therefore no reward other than the pleasurable surroundings. You take to the road because you want to reach a destination, which is your reward. When you invest, the risk is that of loss.
