No-load fund, not load fee.

In the same company , there is generally no transaction fees between different fund. No commision fees for your sell and buy ( the fund has to pay commission fees when they buy or sell stocks.). However, there is a cost--average 1% annually. This charge is on you no matter whether you trade your fund or not.

Also, watch some funds which charge short selling fees--from 1-3 months. If you don;t hold long enough, they can charge you from 0.75% to 3%.
