About our options  



Purchase fee:

A fee charged by some mutual funds when an investor buys shares. This fee is not a sales charge or load because it is paid directly to the fund to offset the costs of trading certain securities.

Redemption fee:

A fee charged by some mutual funds when an investor sells shares. A redemption fee differs from a back-end load because the money is paid back into the fund. Many funds charge redemption fees only when shares are bought and then sold within a specific period of time, generally in an effort to discourage market-timing and short-term trading. Some brokers also charge their clients redemption fees for the sale of securities.

An investment in the fund could lose money over short or even long periods. You should expect the fund’s share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. The fund’s performance could be hurt by:

  • Stock market risk: The chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising stock prices and periods of falling stock prices. The fund’s target index may, at times, become focused in stocks of a particular sector, category, or group of companies. Because the fund seeks to track its target index, the fund may underperform the overall stock market.
  • Investment style risk: The chance that returns from large-capitalization stocks will trail returns from the overall stock market. Large-cap stocks tend to go through cycles of doing better—or worse—than other segments of the stock market or the stock market in general. These periods have, in the past, lasted for as long as several years.
