Diversification 
 • Dividing investment funds among a variety of securities with different risk, reward, and correlation statistics so as to minimize unsystematic risk. 
 • Dividing investment funds among a variety of securities offering independent returns. 
 • In order to reduce risk, it is wise to own the best company in at least 10 industries, depending upon the size of your portfolio. Choose industries that are likely to have better growth than the economy as a whole. Another way to diversify is to buy companies of various sizes in different industries. Size can be measured by the dollar figure for sales, (up to $400M = small company; above $4Billion = large company; middlesized companies are in between.) 
 • It refers to spreading the risks. Diversification occurs when investors buy many different stocks and bonds instead of putting all of their money in a single stock. Similarly, banks can diversify their loans geographically by making loans across the globe instead of a single town. 
 • A strategy that aims to reduce risk, involving the spreading of assets across a mix of companies, investments, industries, geographic areas, maturity dates, and/or other investment categories.
