The term capital accumulation can have various connotations in different contexts:
There is always a possibility that the return on an investment will differ from expectations. The amount of risk that investors are willing to take is directly proportional to the potential returns on their investments. This is because investors have to be rewarded for taking additional risk. For example, US Treasury bonds are one of the safest and lowest yielding investments. The capital appreciation on stocks is much higher, since they are much more risky (a corporation is more likely to declare bankruptcy than the US government).
