why would an investor prefer to invest partly in shares and partly in debentures of a company ?

An investor prefers to partly invest in shares and partly in debentures in order to have regular income with higher returns and at the same time with minimised risk involved. By investing in shares, an investor gets return in the form of dividends which depends on the earnings of a company. Therefore, higher the earnings, higher will be the dividends to an investor. However, there is always a risk involved in dividends due to inconsistency in the earnings of a company. Thus, to minimise this risk involved an investor prefer to diversify his investment by partly investing in debentures. This provides a guaranteed and regular return that too at a fixed rate.
