Upgrade

1. An improvement to an existing product. Some companies, especially technology companies, offer upgrades to customers for free or at a discount.

2. An improvement to the quality of securities in a portfolio. For example, one may sell a stock with a given risk and return and buy another stock with a higher return at the same level of risk. Alternatively, a security may upgrade by itself; for example, its issuer may announce higher than expected earnings, and, therefore, a higher dividend.

3. An increase in a bond rating. For example, if a bond goes from a junk rating to an investment-grade rating, the bond is said to be upgraded. This usually occurs when the issuer reduces its exposure to one or more risks.
