Q. What do you mean by Bond?
Bond: A financial security that represents promise of its issuer (generally a company or a government) to repay a loan over a specified time period, at a specified rate of interest. Bond can then be bought and sold to other investors, over and over again. When rate of interest falls, bond prices rise (and vice versa) - Because when interest rates are lower, bond's promise to repay interest at specified fixed rate becomes more valuable.
