英文名称：Capital Gain 中文名称：资本收益
指资本资产在出售或准备出售时市价高于最初购买价格而产生的收益。资本资产出售后产生的资本收益称作已实现资本收益；未出售时可能产生的资本收益称作未实现资本收益。

1. An increase in the value of a capital asset (investment or real estate) that gives it a higher worth than the purchase price. The gain is not realized until the asset is sold. A capital gain may be short term (one year or less) or long term (more than one year) and must be claimed on income taxes. A capital loss is incurred when there is a decrease in the capital asset value compared to an asset's purchase price.

2. Profit that results when the price of a security held by a mutual fund rises above its purchase price and the security is sold (realized gain). If the security continues to be held, the gain is unrealized. A capital loss would occur when the opposite takes place.

1. Long-term capital gains are usually taxed at a lower rate than regular income. This is done to encourage entrepreneurship and investment in the economy.

2. Tax conscious mutual fund investors should determine a mutual fund's unrealized accumulated capital gains, which are expressed as a percentage of its net assets, before investing in a fund with a significant unrealized capital gain component. This circumstance is referred to as a fund's capital gains exposure. When distributed by a fund, capital gains are a taxable obligation for the fund's investors.
