Your investment portfolio serves a two-fold purpose. One is to grow your wealth so that you can achieve your financial goals and the second is to preserve your wealth so that it is available to you in case of emergencies and can be used by your future generations. In order to accomplish the above, you need to construct a portfolio that can generate the desired returns within the risk parameters specified by you. An asset allocation strategy can help you optimise the risk adjusted returns of your portfolio and in turn assist you in reaching your goals.
