"Which of the following financial products is least likely to have a capital gain distribution?
A Exchange traded funds.
B Open-end mutual funds.
C Closed-end mutual funds."

"A is correct. Exchange traded funds do not have capital gain distributions. If an investor sells shares of an ETF (or open-end mutual fund or closed-end mutual fund), the investor may have a capital gain or loss on the shares sold; however, the gain (or loss) from the sale is not a distribution." 这句话什么意思呢
