Ongoing expenses - Fund expenses incurred annually include management fees. Sometimes a mutual fund may include 12b-1 fee for advertising. Higher fees do not necessarily mean better performance, but high fees may be to pay for extra services. The mutual fund will offer as many shares as investors are willing to buy. These funds need not be bought through a broker.
Most mutual funds are open ended unless otherwise noted.
Many aggressive growth mutual funds have portfolios consisting of many cheap stocks, with the belief that cheap stocks have greater growth potential. Performance - How a fund has done over time. Often past performance is used as an aid to determine future performance. Past performance is not a guaranteed indicator of future performance. Companies with very high ratios of greater than 30 are considered to be overpriced.
