This experimental study investigates portfolio composition choice for different types of financial assets and different levels of wealth. For a group of financially sophisticated executive MBA students with work experience in capital markets, the findings of this study indicate that the proportion of wealth invested in risky assets increases with wealth for all portfolio compositions examined, and increases with the degree of asset risk. This proportion is found to be as much as three times higher for common stocks than for options: For stock portfolios, it increases from 33% to 44% over the five wealth levels examined, and for options it increases from 11% to 17%. These results may imply a decreasing rel w proportions of their wealth in risky assets possess the following characteristics: they do not invest in options in real life; they sometimes buy lottery tickets; they assign a higher risk level to options than to common stocks; they are female; and they are employed.
